This week I posted a great image of an elusive leopard on the Snapshot Serengeti facebook page. I have a real soft spot for these large cats that stems from my first foray into the world of camera-trap studies. Back then I lived on a small nature reserve in South Africa where leopards were the top predator. Without lion present and an abundance of prey the leopards thrived there and our study looked at the population density on the reserve. The interesting thing with the study was that we almost never physically saw a leopard on the reserve yet we were able to get heaps of camera-trap photos. It was although these leopards had learned that yes this was a great place to live, just keep your head down when one of those humans comes by.
I have been thinking about what draws me to leopards more than the other big cats of Africa and decided it’s the catty-ness of them. Now don’t get me wrong, lion and cheetah are definitely cat like too but somehow they are out done by the leopard.
Let’s take the lion. King of beasts they may be but really, hanging out in prides, what’s that all about. That’s what dogs do right? And cheetah, well with those only semi retractable claws and that speed over the plains, well, it could almost be a greyhound.
Now back to the catty-ness of leopards. Well they slink about, pounce on anything they can get away with, shoot up trees at the drop of a hat and generally act aloof just like you average house moggy. One more thing they share with their diminutive house cousins, they love to sit in boxes. Ok maybe not boxes but I have seen leopard tucked up all cosy in various natural alternatives. The picture below I took in the Kgalagadi where this leopard was sound asleep on top of a giant sociable weaver nest.
The beautiful cryptic pattern of the leopard is one of its best adaptations that allow it to thrive in all kinds of habitats across Africa and Asia. Their coat pattern helps to break down their overall shape and they use broken terrain and vegetation to conceal their presence as they stalk close to prey and then ambush. More than capable of taking large prey leopards will happily snack on rodents, insects and small mammals if the opportunity presents itself. This camera-trap image shows a leopard with a zebra kill. The actual event was witnessed by a colleague who confirms that the leopard came out of nowhere and caught the zebra totally by surprise.
Despite this seemingly remarkable ability to blend into the background leopard do not go unnoticed by man and recent studies have highlighted that leopard numbers too have plummeted as they are targeted for their skins, as trophies and just killed as pests. They seem to be declining in the same way they thrived, quietly and out of sight.
Well it is that time of year again when the winners of the prestigious wildlife photographer of the year awards are announced.
Having a browse through this year’s winners I notice with a touch of sadness but a good dose of hope just how many of the photos touch on the demise of wildlife and have a conservation message. Brent Stirton’s moving image of a poached black rhino although tragic is a strong weapon in itself in the fight to change the hearts and minds of those people that covet rhino horn.
One of my favourite images is in the bird behaviour category. The much maligned marabou stork is the subject and the shot was taken in the one spot on this planet that Snapshot Serengeti fans know so well, yes the Serengeti.
But the story doesn’t end there. The photographer who was awarded finalist in the bird behaviour category is well known to us. Daniel Rosengren worked for the Serengeti Lion project for 5 years in the field with the most enviable job going. He spent every day following the study lions getting to know them intimately and generally building up the rich source of study data that this 30 year+ project has gained.
Of course when Dr Ali Swanson came up with her wonderful idea of seeding the area with 200 odd camera traps and the Snapshot Serengeti project was born it was Daniel who looked after our precious cameras for several years. So we have a lot to thank him for.
Daniel moved on from the project in 2015 to pursue a career as a professional wildlife photographer and we congratulate him on his achievement this year in the wildlife photographer of the year award. Well done!

This week we have had a lot of great images that our community of classifiers have flagged up for discussion. Numbers seems to have been the theme, with unusual sightings of two aardvark stepping out together, elephant herds and lion prides.
My favourite is the unusual grouping of three dikdik, almost certainly a family unit, all looking behind as a bushbuck saunters past.
So here is a taste of the action:
What will you find this coming week? Don’t forget to share the best or the unusual with the rest of the community. Head over to https://www.snapshotserengeti.org/
Although mammals are the target for the Snapshot Serengeti camera-trap project we do on occasion capture other things, humans, vehicles, reptiles and birds. The most common of the birds is probably the larger ground patrolling species like kori bustard, secretary bird, guinea-fowl or the birds that are attracted to mammals like oxpeckers, egrets. It is actually surprising just how many species we have picked up over the years.
One of my favourites though has to be the owls. Always such fascinating creatures they are often loved but often feared too. Their nocturnal, silent flight lends to the mystery but anyone who has been around owls much will know that they can be noisy birds when it comes to calls.
So who might we encounter in the snapshot Serengeti camera-trap images. Well there are 9 species that call the Serengeti home:
- Barn owl – Tyto alba
- African marsh owl – Asio capensis
- Spotted eagle owl – Bubo africanus
- Verreaux’s eagle owl –Bubo lacteus
- African wood owl – Strix woodfordii
- Pear-spotted owlet – Glaucidium perlatum
- Southern white-faced scops owl – Ptilopsis granti
- African barred owlet – Glaucidium capensis
- African scops owl – Otus senegalensis
The barn owl found on every continent except Antarctica is probably familiar to us all. The spotted eagle owl, a medium sized owl is just that, heavily spotted and barred overall greyish. The similar sized wood owl sticks to more densely wooded areas and is a darker chocolate brown. This is a rare bird for the snapshot habitat.
The largest owl we will encounter is the Verreaux’s eagle owl, pale grey the most obvious distinguishing feature is bizarrely its eye lids, they are bright pink. Unmistakeable if you get a good view.
As for the small owls two are actually reasonably active during the day, pearl-spotted and barred owlets. Quite hard to tell apart the pearl-spotted has white spotting on its back where as the barred has, you guessed it, a barred back. However if you are ever lucky enough to hear a pearl-spot in the wild they are unmistakable. It has a slow single note, rising pitch call that builds up to deflating drawn out descending notes. Hard to describe but its other name is the orgasm bird!
We would be lucky to pick up a scops owl, the smallest of all these owls. It remains hidden in trees all day and hunts insects at night.
The African marsh owl is unusual in that it roosts on the ground, tunnelling into long grass. Superficially it resembles a barn owl but the pale facial disc is rounder than the heart shape of a barn owl. They mostly eat rodents.
The white-faced scops owl has a very striking white face framed by black bands. The rest of its body is pale grey. Size wise it is slightly bigger than the two owlets.
