Those of you who follow our Facebook page will have seen recently that Meredith Palmer, one of Snapshot Serengeti’s scientists and PhD candidate with Minnesota University just published a paper in African Journal of Ecology with the catchy title;
Giraffe Bed and Breakfast: Camera traps reveal Tanzanian yellow-billed oxpeckers roosting on their large mammalian hosts.
The paper highlights one of the more unusual behaviour traits documented by our cameras and discovered by our classifiers of yellow-billed oxpeckers (Buphagus africanus) roosting on giraffe at night time.
Those of you that have been with us a while may have had the pleasure of finding one of these night time images of giraffe with oxpeckers tucked up safe and snug between their back legs. In fact I wrote a blog about this back in 2014.
Two species of oxpecker are found in the Serengeti, the red-billed and the yellow-billed oxpeckers. Whilst the red-billed will feed from a wide range of hosts from impala and wart hog to hippos the yellow-billed oxpecker is more discerning and prefers large hosts such as buffalo, eland and giraffe. The problem with this choice is that these animals are far roaming and if the birds were to find trees to roost in at night, and these can be sparse in the Serengeti, the yellow-billed oxpecker could struggle to locate its host the following morning. It seems they have overcome the problem by staying over on the hosts. What’s more is these clever birds have opted for the premium rate rooms where they are not disturbed during the night for, as is well documented, giraffe almost never lay or sit down at night time preferring to stay upright.
So although during the day yellow-billed oxpeckers are found on several large mammal hosts most of the night time images are of giraffe roosts. It seems they also have a preference for the groin area of the giraffe. It is not hard to imagine that this would be the warmest safest spot on the giraffe, the cavity created where the two hind legs meet is spacious enough to accommodate a small flock of birds and of course is also very attractive to ticks so if they fancied a mid-night snack…..
It is these unexpected discoveries that make the project so exciting and worth all our effort in taking part so next time you are racing through the classifications take a little time to have a closer look at the images, you never know what is waiting to be discovered.
If you want to read more about Meredith’s paper you can read the following:
So the new Snapshot Safari base camp for Snapshot Serengeti is a month old and teething problems aside all seems to be going well. I just wanted to take this opportunity to welcome all our new classifiers and to say a big thanks to all our old classifiers who have stuck with us. But most of all a massive thank you to our moderators who have worked so hard to make the transition run so smoothly. They have answered all your questions and queries without my back up due to the unfortunate timing of my own African field trip falling during the launch of Snapshot Safari.
It is not the first time Snapshot Serengeti has seen a big change. Some of you may remember its first outing as Serengetilive back in 2011. In those days things where a lot slower, you started classifying by first choosing an individual camera and working through it. There was an option to skip images, leaving them for someone else. Of course what ended up happening was all the hard to identify images and all the no animal grassy images were left to the end so that some people never got the chance to classify any animals.
We then progressed, in 2012, onto the Zooniverse platform and saw a huge change to the way things worked. Suddenly there was a lot more interaction between the scientists and the community. This was when the famous algorithms where developed by Margaret Kosmala and Ali Swanson and their team to act as a fail proof to anyone incorrectly identifying images.
We are all very grateful for their hard work and dedication that results in us classifiers being confident that our guesses won’t mess everything up.
So I hope that you are enjoying this third incarnation of Snapshot Serengeti and can be proud that it has worked so well over the years that it has spawned so many new projects.
My own field trip to Africa is coming to an end this week and I will be back in the land of internet connection. I will then hopefully be bringing you more regular posts and more updates on the project itself and how it is progressing. In the meantime don’t forget to check out our facebook and twitter pages.
Camera-trapping has vastly opened up the possibilities of studying animals in the field in a relatively unobtrusive manner. Leaving a bunch of camera-traps clicking away 24/7 over a long period is generally cheaper than employing researchers to stay in the field providing them with accommodation, food and vehicles.
However it has its drawbacks. Good field skills are only learned over time spent in the field and although field researchers cannot operate 24/7 like the camera-traps they are less impartial observers noticing all kinds of fine details surrounding that which they study.
It is these observations that stimulate and inform new scientific questions and drives the understanding of the world around us. I am not suggesting that the results of camera-trap studies can’t also do this but since the days of the first naturalists it is being in the field that nurtures the very interest in studying wildlife in the first place.
The researcher who knows their study area well will be at an advantage to one who has planned from afar after using GIS. I know because I have been both. My first camera-trap project was on a reserve where I had lived for three years and that helped me know intuitively where I should place my camera-traps. On the other hand my latest project involved a very fine time window and I had to set up camera-traps on an unknown farm within two days of arriving. By the end of the 8 week period I was just starting to get a better feel for the place and could have kicked myself for not placing my cameras in the optimum places. When I went back to collect the cameras I found myself wading thigh high through a carpet of small yellow daisy-like flowers that left me coated waist down in a yellow stain. Had I have known the farm better realised this plant grew only in a few areas and could have avoided it entirely and saved myself the turmeric skin wash and a lot of miss-triggers.
My latest trip to Africa reminded me of why living in the field is so rewarding. Whilst the camera-traps are diligently collecting your data it gives you the chance to observe without frantically thinking of your research question, you can take time to take inspiration from the broader environment.
Near my tent was an old dead knob thorn tree that had five white-browed sparrow-weaver nests hanging like straw balls from it. Each night at dusk a pair of sparrow weavers would fly into the tree, call loudly as if claiming the spot and the female would dive into her preferred nest. The male would remain up high above waiting. Just as the last light was fading 3 or 4 small dark shapes would arrive and the sparrow weaver would chase after them squawking disapproval. Having seen them off he would come back and settle himself into the nest of his choice retiring for the night. Watching closely revealed, a few minutes later, the return of the invaders; two pairs of black-faced waxbills. They alighted at the top of the tree and cautiously made their way down towards the remaining nests finally one by one slipping quietly into the unused nests one couple per nest.
The thing about this little drama was that it was played out every night for over two months. None of the birds seemed to alter their routine and none where actively breeding at the time, they just had their bed time ritual. This was the kind of observation that the camera-traps will never quite capture as well as a human. In just the same way, although Snapshot Serengeti would not exist without the cameras it would be nothing without the human, citizen scientists behind the scenes sorting out the images. Even with computer recognition programs on the horizon I believe it would be foolish not to still use humans who’s innate sense of life will always pick up on something that is slightly odd, unusual or different about an image.
Most people these days know what a hashtag is and it can be a powerful tool in terms of searching for like content on social media. Here at Snapshot Safari hashtags are useful to find unusual sightings and to search for images of specific animals. Having said that, used wrongly or overly zealously hashtags can become a nightmare. This guide is to help you know when to hashtag and when not to hashtag.
When not to hashtag
If you are not 100% sure of the identification of an animal then don’t hashtag. This is important as moderators spend a lot of time trying to get you to correct your wrong tags and it is counter-productive to the usefulness of hashtags for searching if the searches come back with wrong images. You can still flag the image for discussion where moderators will hashtag it if deemed necessary.
It is not necessary to hashtag every image you flag for discussion. Try and be selective and choose unusual images or those with some scientific relevance. Think what might be useful to the scientists or other citizen scientists.
Don’t give one image more than one hashtag. Labeling #wildebeast #wildebeastfrolicking #wildebeastresting all for one image is not helpful. Stick to using one basic description.
When to hashtag
Use a hashtag when you discover something rare or unusual; for instance a night image of giraffe with oxpeckers roosting on it, or a large pride of lions with young cubs.
Hashtag images you think are particularly impressive in terms of photographic quality. Hashtagging every image of wildebeest migrating is not necessary but if you find one image that has the wildebeest lit with a stunning backlight then go ahead and let us know.
The main message here is to think before you hashtag, why am I tagging this image?, does it really warrant it? Use them sparingly. If in doubt, leave it out.
The original Snapshot Serengeti platform will be deactivated on February 1st, 2018. There are still images left to classify, so please help us by finishing as many as you can before February 1.
With the launch of SnapshotSafari just eight days away, we would like to share a detailed explanation of the new interface and note a few significant changes. The participation of Snapshot Serengeti citizen scientists and moderators over the past seven years has provided researchers, conservationists, and computer scientists with invaluable information regarding wildlife populations, online classification systems, and citizen science platforms. We hope that you will continue to work with us on the new platform, so that we can continue to expand and improve our methodology.
Here is what you can expect to see on February 6, 2018:
Multiple sites: Moving Beyond the Serengeti
Figure 1. SnapshotSafari Parks & Reserves
As mentioned in a previous blog post introducing SnapshotSafari, Snapshot Serengeti will not be going away. Instead, it will become one of several camera trap sites that volunteers can select. The SnapshotSafari landing page will link to individual pages for each protected area and provide news and updates about the network overall and/or individual sites. The charming wood-panel background will be changed from time to time, showcasing interesting classified images or letting users know which sites need the most help.
When a user clicks on a site such as Snapshot Serengeti from the landing page, they will be taken to a page that resembles Figure 2.
Figure 2. SnapshotSafari interface.
For the initial launch, there will be six sites to choose from. These new camera trap grids are sending us images from Tanzania, Mozambique, and South Africa. For the first few months, we will release additional sites every three weeks, so make sure to check in often to see if a new location has been added. To navigate between the sites, simply log on to SnapshotSafari and select the reserve you’d like to visit. To return to the home page and go into a different site, click the SnapshotSafari tab at the top of the page.
Classification – What’s different?
Good news for those of you who have been with Snapshot Serengeti for years and are used to the classification system: as you can see in Figure 1, the interface will remain mostly the same.
Here’s how it works: A picture or series of up to three pictures will appear on the screen next to the species’ name list. When you click on a species name, a brief description and a few pictures will appear. If a volunteer isn’t sure of the name of the animal, there are a few tools they can use to help narrow down their choices. Citizen scientists can look at examples of tail shape, animal build, the color and pattern of skin/hide, and horn shape to identify the wildlife in each photograph. The “Looks-Like,” tab has changed slightly, providing silhouettes of animals (Figure 3) instead of descriptions.
Figure 3. “Looks-Like” Tab
Once a species is selected, users will still have the option to choose the number of individuals and record any behaviors. While the look has changed, the choices remain the same (Figure 4).
Figure 4. Number of Individuals and Behavioral Information
Have you ever wanted to zoom in on a picture to get a closer look at far away animals? Now you can! SnapshotSafari allows users to zoom in and out, click-and-drag the image, and rotate the image. Some of the new sites have new species, so you can expect to see a few new options on the list of potential species, such as nyala and klipspringer.
There will be several field guides available, providing users with clear images and detailed information about different groups of animals (e.g. deer, birds, predators, etc.). These are always available for reference to help volunteers hone their classification skills and provide information on the most challenging species to identify or distinguish between. Some of these field guides utilized information and images collected on the Snapshot Serengeti discussion pages. A special thanks to those of you who helped collect related images and develop tutorials; know that your efforts have been recognized and contributed to the development of these field guides.
Volunteers still have the options to, “Collect,” and “Favorite” images. After identifying the wildlife in the photograph, one can choose between, “Done,” or “Done and Discuss.” Clicking on, “Done and Discuss,” will take them to the, “Talk” section of each site. More details on the discussion section is provided below.
There are still pictures that need to be classified at www.snapshotserengeti.org. We are hoping to finish these classifications before the launch of SnapshotSafari. If we don’t finish with the remaining images, they will be uploaded in batches to the new SnapshotSafari website in Snapshot Serengeti’s unique page.
Collections & Discussions
UPDATE: The Snapshot Serengeti website will no longer function after February 1st. When SnapshotSafari launches, the main www.snapshotserengeti.org site will be redirected to SnapshotSafari. The talk.snapshotserengeti.org site won’t be changing at all in the short term. In the long term its contents will be archived permanently, including your collections and favorites.
Each site will have their own discussion forums under the associated Talk section. We are happy to announce that users will no longer be taken to a separate site or tab to participate in or read through the discussions; it is all available on the Zooniverse site! If you want to ask a question, start a discussion, or share a cool picture, you can do that by clicking the Talk tab. When you are ready to resume classifying, you just click on the Classify heading to return to the site’s photos.
Our moderators and a group of volunteers have gone through the discussion forums of Snapshot Serengeti, and they selected several discussion topics to transfer to SnapshotSafari. The majority of the Serengeti forums will not be transferred, but will remain on the old Serengeti site.
Where/When can I find out more?
This Wednesday we will start a countdown for the official launch of SnapshotSafari, featuring detailed descriptions of the six new sites being featured in the initial launch. You can also post your questions in the Serengeti discussion forums until February 1st and follow us on social media for updates.

You are probably aware that the 225 camera traps of Snapshot Serengeti are set out in a grid pattern, spaced every 1km over a part of the Serengeti National Park. It sounds relatively simple but actually there is a lot of painstaking scientific pondering as to how exactly to set out your camera traps.
Over the last couple of decades there has been much debate as to the best way to design a camera trap study. The main choice, in terms of placement pattern, is whether to place your camera traps randomly or selectively and what kind of spacing/density to use.
Truly random is to grid your study site and then let a computer randomly choose which grid squares to place the cameras. Alternately you can choose a line or grid and place your camera trap at regular intervals regardless of where that may fall, still a random point. With selective placement each site is carefully chosen for a specific feature.
In reality most projects use a mixture of the above methods and the best method is really determined by what your scientific question is. For instance, if you where trying to acess the number of leopards in a given area it is better to place your camera traps strategically in places you know or guess leopards are most likely to pass rather than using a randomised method. However if you are carrying out a census of an area and wish to know what species are present then a randomised grid is ideal.
As I said a mix of methods is often used. Imagine setting out a grid in the comfort of your office on your computer. It looks good, covers a large area and promises good results. Once out in the field you navigate to your carefully worked out GPS reference point only to discover it is slap bang in the middle of a marsh or in a thick overgrown patch of thorn trees. This is where the scientists allow themselves a little leeway. Often they will take the GPS point as home base but choose an ideal spot within a certain radius of this point where perhaps there is a game trail or some other sign of animals passing, thus allowing them to select a good site within the vicinity.
I have recently had experience of this type of placement and I can say the work done in selecting your study site and then laying out your grid onto a map is laborious but not nearly as much as stomping through the bush keeping your fingers crossed that your next randomly selected site will be perfect. Turning up to emplacement three to find a thick tangle of vegetation is a little soul destroying, mostly you wonder if any animal is likely to bother to pass that way. The reality is that you normally find a spot that is better within 10 meters and with some slight pruning of the vegetation the sites can often turn out remarkably productive.
So that is the placement sorted but there is a long list of other agonising variables to consider, what settings to use on the camera trap itself, how many to use and how long to keep them up. Believe me every scientist designing studies deliberates the pros and cons of these factors and worries incessantly about if they have made the right choice. You don’t want to set up all you camera traps and leave them for a few months only to find your set up was not great, something which happened to me recently when I chose to set the camera trap on high sensitivity to make sure I had every chance of capturing the small, fast critters. The problem was it was so hot, 40°c plus, that the ambient waves of heat set the camera trap off almost permanently between 12pm and 5pm leaving me with 2000 images of nothing. I have had to compromise and reduce the sensitivity to avoid all the miss triggers; hopefully it won’t miss too many small things.
Snapshots camera traps have now been up for over 7 years so most of these teething problems have been ironed out. But as with the best laid plan you cannot control everything, the odd camera still malfunctions as I am sure that our regular classifiers can attest to!
When living in the bush in Africa your life becomes attuned to the rhythms of nature. Up with the sunrise, the spurfowl, guinea fowl and francolins won’t have it any other way, their raucous calls start well before the sun is actually visible. Physical work can be done until about mid day and then if possible its best to seek shelter till around 4pm when the sun is at least not high enough to cook you yet still pretty hot. By 8pm its dark so there is nothing else to do but sit back around a fire and let the night envelope you.
I am living so basically at the moment, my clothes are starting to look shabby after two weeks of hand washing in minimal water. I am however improving my skills daily at cooking on an open fire. It is amazing what you can do with a skillet, a pot and bits of old rebar and wire. I may have invented a new dish last night, Christmas Eve, when I conjured up a gemsbok stir fry.
The wood here gives new meaning to the term hard wood. Luckily for me there is a ready supply of wood due to the need for bush clearing on this cattle farm. Just a few pieces are enough to get really good coals glowing to cook over. They use a deep three legged cast iron pot in Africa for cooking stews, known as a potjie here in Southern Africa. I might even try my hand at bread next.
So last night after a good feed, Trev and I sat contemplating the embers whilst watching nightjars and bats hawking what looked like flying termites. It has rained recently triggering the eruption, earlier we watched guinea-fowl, hornbills, starlings, drongos and a whole host of other small birds running back and forth slurping them up straight from the holes before they could even get airborne. There is a constant suzzz of insect noise interrupted by the screech of barn owls and the odd jackal.
Then there is a deathly screech to rival that of the barn owl, what is it you ask? well it’s me. Something has just ran up my leg across my back up on to my head and then dropped down again to the ground between my feet. I am not usually given to screaming like a girl and creepy crawlies don’t usually bother me, but there is nothing quite like the dark to bring out the pathetic in us. So a quick scrabble for flash lights ensues and the culprit is spotted.
It’s a solifuge, otherwise known as a sun spider. Not actually a spider, though belonging to the same class, arachnida, they form an order by themselves, solifugae. They differ from spiders in not having silk glands and therefore do not spin webs. They appear to possess 10 legs but in fact the front most pair are actually pedipalps that act as sensors and aid in feeding. They are voracious predators and will eat anything they can overpower such as spiders, scorpions, insects and invertebrates.
Totally harmless to humans they do however install a lot of fear. This is partly due to two behavioural traits. If disturbed in the day the solifuge will head for the nearest dark place, often the very shadow cast by the human that caused the disturbance in the first place, giving the false impression that the solifuge is running at you in attack mode. Similarly at night they will follow a light source, again, often that of a human with a flash light.
The second trait is that they move like greased lightning. They are constantly zipping from here to there in a frantic search for prey to keep their high metabolism ticking over. They have also been known to take human hair to make their nests.
You are not likely to pick one of these up on Snapshot Serengeti’s camera-traps but if you ever get the chance to observe one of these arachnids going about its daily business it is really very fascinating, if of course you can get over your human fear.
*This weeks blog was written by Jamee Snyder, project coordinator and administrative assistant with the Lion Lab, University of Minnesota. She tells us all about a wider a project that Snapshot Serengeti has evolved into and what we can look forward to in the near future.*
Seven years ago, the University of Minnesota Lion Center set out 225 cameras in Tanzania’s Serengeti National Park. These cameras have recorded over 50 species including some of the most threatened species on Earth. With help from over 140,000 citizen scientists from around the world, millions of photographs were reviewed and classified over the past seven years, which provided park managers, conservationists, and researchers with the necessary information to analyze African wildlife population dynamics. This collective effort is a major contribution to ecological research, allowing for the evaluation of long term trends in wildlife populations as well as best practices in conservation management of charismatic african mammals.
Snapshot Serengeti was one of the first camera trap surveys to document wildlife populations in a national park and is now one of the longest running camera trap surveys in the world. We have learned a lot over the years, from how to keep our cameras safe from hyena jowls to retrieving data from memory cards that have gone through a wildfire. We are continuously looking for ways to improve this project.
Thanks to years of experience, your participation, and help from several organizations in the U.S. and Africa, we are excited to announce that Snapshot Serengeti is expanding into an international conservation initiative called, “SnapshotSafari.”
Don’t worry! Snapshot Serengeti isn’t going anywhere. In fact, it will remain essentially the same as we transition into our new platform. The discussion forums and personal image collections will still be available to current and future users. Now, participants will be able to see numerous other parks in addition to the Serengeti. SnapshotSafari will showcase camera trap images from multiple camera trap grids inside dozens of parks and reserves located in six African countries. Intrepid citizen scientists will be able to choose from various exotic habitats, including but not limited to: the Sand Forests of KwaZulu-Natal, the Lowveld of Limpopo, the Fynbos of South Africa’s Cape, and the Karoo desert, in addition to such remarkable ecosystems as Mozambique’s Niassa Reserve, Tanzania’s Ruaha National Park, Swaziland’s Mbuluzi Game Reserve, and Botswana’s Makgadikgadi Pans National Park.
By incorporating multiple sites, we can ask more complex questions regarding African wildlife populations and the factors that contribute to ecosystem stability. For example, researchers can compare population dynamics of reserves that are fenced versus those that are unfenced, or theycan evaluate the environments that successfully host multiple predator species without depleting prey populations. Researchers at the Lion Center will use this dynamic platform to investigate the cascading effects of large mammal reintroductions and ways to limit direct human interventions while still maintaining stable ecosystems within fenced reserves. SnapshotSafari provides an opportunity for participating reserves to collaborate and subsequently develop the most effective conservation strategies for protecting biodiversity.
We are working hard to get SnapshotSafari ready to launch in January. We just completed beta-testing, and the feedback has been very positive. To all of the citizen scientists who participated and to those who continue to be involved with Snapshot Serengeti, we are extremely grateful!
Now, we need your help to finish classifying the final series of images on our original platform, Season 10, at http://www.snapshotserengeti.org before we initiate SnapshotSafari, which will host Season 11. We are very close to finishing classification of these images, so don’t hesitate to invite your friends and family to take a trip to the Serengeti through the lens of one of our camera traps and classify wildlife. Let’s push this meter to the end!
Stay tuned for an official count down, so you can be one of the first to participate in SnapshotSafari and contribute to our collective knowledge and ability to successfully conserve African wildlife.
You know you are in Africa when you wake up at the airport lodge on the edge of a capital city and stepping out from your room you come face to face with a bird that towers above you. Ostrich aside the dry heat of the Kalahari leaves you in no doubt you are in Africa.
I am in Namibia where I will be for the next two months. I am working on a cattle farm in the Waterberg plateau that is part of a greater nature conservancy. I have already got my camera-traps out, hopefully snapping away as I write. The idea is to look at how camera-trap spacing affects the chances of recording smaller mammals. There are plenty of those here, bat-eared fox, jackal, caracal, mongoose, pangolin, hare and aardwolf to name but a few.
The great thing about using camera-traps is that now they are up I have some weeks to wait before moving them so I have plenty of time to immerse myself in the African bush. I have already clocked up over 100 bird species in less than a week, its taking a while to get my ear back in gear, I keep hearing tantalisingly familiar calls but can’t quite remember who they belong to. It is the start of the rainy season and subsequently the breeding season so there is an awful lot of activity. The binoculars are back living on my shoulder and in use every few minutes.
The bush here consists of a lot of small bushes and trees interspersed with small open grass patches. Plenty of sickle bush, raisin bush and buffalo thorn. I forgot how hard it is to walk through, constantly getting hooked up on vicious thorns that grab at you as you pass.
The best bit of the trip is living in a tent, ok afternoon naps are impossible in the heat but you get to wake up early to the birds calling. The francolins and spurfowl are calling before the sun even rises. There are white browed sparrow weavers building nests in a tree near the tent that have the loveliest melodies. Then there is the night shift. It is pretty hard to fall asleep sometimes when the noises just make you want to get up and investigate. So far I have come face to face with a honey badger sniffing around our fire and several genets. The jackal’s shrill call is omnipresent but the one I listen out for is the rasping call of the leopard. I haven’t been disappointed, every other night that sound rumbles through me.
My internet connection is not so great but I should still be making regular posts for Snapshot Serengeti and there are still plenty of images to classify. We would like to run season 11 in the New Year if we can get season 10 completed. I may even have the odd camera-trap image from my Namibia project to share. Watch this space.
One of the groups of animals that seem to prove quite tricky to tell apart on Snapshot Serengeti are the small carnivores that belong to the canid and hyenid family. That is to say the jackals, black-backed and side-striped, the bat-eared fox and the aardwolf.
There are good reasons for this. Firstly they are predominantly nocturnal, though the jackals can often be seen in day light hours. Secondly they are small and constantly on the watch for larger predators. Studies have even shown that similar species such as coyotes are rather camera-trap shy so it could be possible these African cousins are avoiding the cameras. I noticed when looking for bat-eared fox images particularly that there are very few close up images, the foxes always seem to be in the distance. Something to maybe study?
So back to classifying, what’s the best way to tell these species apart?
Let’s start with the jackals, the most dog–like of the Serengeti’s small carnivores.
The first thing to note is there are actually three possible jackals to be found in the Serengeti but I will stick here to the side-striped and black-backed as the most common, the golden jackal doesn’t come up so often on our cameras but looks broadly the same as the other two with slightly more uniform colouring.
Jackals have dog like proportions with the shoulders and hind end approximately the same height. They have very pointed muzzles and large pointed ears. The black-backed can be distinguished by its black saddle running from the back of the neck through the shoulders up to a point at the top of the tail. It is flecked with white hairs giving a grizzled appearance. The rest of the body is a sandy colour. The side-striped is more uniform grey brown with a flash down its side both light and dark but lacking the saddle. The tip of the tail is often white. Their ears are smaller than black-backed jackal.
The bat-eared fox meanwhile is a strange looking creature. All three of these carnivores have large ears to help them locate prey but the bat-eared fox wins the prize. Its ears dwarf its little face which is very small. They need these huge ears to locate their insect prey. Over all bat-eared foxes are the smallest of the three and have a rather plain silver/grey coat with dark legs, ears and upper parts of its thick bushy tail. If you are not sure look at the over all posture. The jackals hold their head high on a strong neck but the little bat-eared fox often has his head down and appears to have no neck.
Aardwolf, although not canids, are included here because in size and shape they are very similar to the other two. Fortunately these guys have distinctive striped coats which help separate them from all but the much larger and very rare (in Snapshot Serengeti) striped hyena. The aardwolf seems to have a rather thick long neck and a much more hyena shaped heavy muzzle.
So the tip here is to look closely at body form as well as colour, hopefully seeing these images of the three together will be helpful next time you get stuck classifying.
