Watching For Whisker Spots
I recently met with Meritho, who has to have one of the best jobs in the world; he is paid to watch lions.
Yes it does sound like the dream job, following lions all day, observing their behaviour and trying to identify them but Meritho’s job is not quite the dream it would seem. For various reasons the long running Serengeti Lion Project was put on hold for three years which meant that all the diligently followed lion prides known intimately by researchers have done a lot of growing up, giving birth and dying. Not surprisingly it’s hard to work out who’s who and who belongs to whom.
Meritho has inherited the arduous task of re-establishing the family connections and splits within the Serengeti’s lion prides. Armed with some old scribbled maps and a stack of cards with drawings of lion whisker spots he has to compare each lion he sees with these cards to help him workout just who is still out there in the Serengeti lion society. Of course the camera trap images help a little but only if they capture the perfect close up, in focus image of the lions muzzle showing the spot pattern. In reality its all down to traipsing around the Serengeti looking out for lions and comparing each and every one with the hundreds of hand drawn cards.
I asked Meritho how he tackles this mammoth task. Making a plan is key, he says, with most of the tracking collars non functional you have to think hard where the lions might be and just drive around looking for them.
Ok you can narrow it down a bit as Meritho does by getting up by 5 am, making sure your vehicle is puncture free and stocked with fuel and water and then heading out to try and catch the big cats as they finish up for the night. At this early hour they are often looking for a good spot to spend the day or joining back up with young cubs that have been left somewhere safe whilst mothers where out hunting. All this movement increases his chances of running into lions.
Most of the time Meritho is far from base so eats lunch in the car only returning home around 5:30 as it starts to get dark. Its long hours and most of the time you are either sitting waiting or driving, briefly interspersed with spells actually watching the lions. In return they themselves are often infuriatingly sleepy and won’t lift their heads for you to get good pictures of their whiskers meaning even when you do find lions you cannot always see who they are.
So far he has managed to identify around 150 individual lions and is monitoring around 18 prides. Monitoring lions gives him a sense of pleasure that he is out there doing a scientific job he never dreamt, as a Tanzanian, he would get the chance to do. He says ‘ when I look at where I come from and where I am going as a researcher it brings a lot of value to my life, knowing what research means is one thing but doing research makes me feel like I am contributing something to the world and my home environment’. He is gaining knowledge and experience daily and hopes to continue doing great things within conservation, an inspiration to aspiring local scientists.
It’s great to know that Meritho is out there following the lions again and that the Snapshot Serengeti cameras are still going to be clicking away for sometime to come.
Could you explain a bit more how the ID-process works? Is there a different number of whisker spots or a different pattern? It seems awfully tricky to me.
Each individual lion has a different pattern of whisker spots that make it identifiable. In general you imagine the spots being in rows but the reality is sometimes the spots will be out of line or hunched up to one end with a gap before continuing. All this subtlety means that with a practiced eye and a good close up view you can id a lion. It isn’t easy as the patterns don’t vary greatly. Sometimes other features like notches in ears or scars can help when you know the lion well but of course lions can always get new notches and scars where as the spot patterns stay from cradle to grave.
Thanks a lot!
