In a Tree
Carcasses can be found almost everywhere. Over the course of the migration, thousands will be found in the river. Lions and hyenas often enjoy dragging their kills into the darkest recesses of the bush but more often then not, carcasses are lying out in the open plains just waiting for the vultures to find them. On rare occasions, dead animals can get dragged into trees. In my first year, I had the pleasure of watching two White-headed vultures feed on a treed Thompson gazelle carcass before being pushed off by some tourists who seemed more interested in the carcass than the birds.Read more...
The Unexpected Carcasses
It is the wet season (although we haven’t actually had any rain yet) so I wasn’t really expecting to find many carcasses – and I haven’t. But what I have found has been particularly interesting. A zebra carcass with three dogs and a handful of vultures, a hyena carcass with eight Lappet-faced vultures, two lion kills in a day (both of which got eaten by lions, not vultures), and the mutilated mass of a cow that was partially eaten by hyenas, then slaughtered for human consumption, and finally nibbled on by the birds.

What a day!
What a day! Let me start from the beginning. I woke up this morning at 5 AM. It was day two of trapping. Day one had been less than successful and I was beginning to wonder if I had been crazy to think that I could trap vultures during the low season. You see when the wildebeest come to Masai Mara in July so do the vultures. For three months, the park is overflowing with carcasses and scavengers. Trapping is made easy during this time, at least trapping African white-backed and Ruppell’s vultures, which are exceedingly common with upwards of sixty birds at each wildebeest carcass. But trapping Lappet-faced vultures is tricky. Only a few birds come to each carcass, they come late which means they are less likely to get trapped (since you have to put the trap down at the beginning and can’t go back and add it to a carcass without scaring all the birds), and they just tend to be a bit more cautious. So I had the “brilliant” idea that the low season would be the ideal time to trap Lappet-faced vultures with fewer African white-backs and Ruppell’s around. But after spending all of yesterday trying to trap with no success, I was starting to worry if I could trap anything this time of year. Nonetheless I awoke with a feeling of mixed panic and hope and set out to trap.Read more...
Rumble in the Jungle
Large carcasses are scarce this time of year. With the tall grass, the herbivores have plenty to eat and the big cats and hyenas have a hard time catching their prey, who have freedom to roam wherever they please. The cheetahs seem to be the only ones having any great success, perhaps because they rely more on speed than stealth. There also aren’t a lot of animals dying this time of year, precisely because there is so much lush food and water to go around. There are still calves being born, some of whom won’t make it and the occasional diseased or injured animal that might keel over. Needless to say, the vultures have to work hard to find their food and when they do discover something, they work even harder to ensure they get a bit.Read more...
The world is a scavenger’s stage
We sat at a carcass for nearly five hours yesterday. Not because nothing came, but because the vultures refused to leave. Jackals found our carcass early and I’m afraid the birds didn’t get much, but it didn’t stop them from coming. We had 11 African white-backed vultures, 5 Lappet-faced vultures, and a couple of Hooded vultures. The white-headed vultures have been noticeably absent but the Hoodeds seem to be coming back this year.Read more...
Lions, hyenas, and dogs, oh my
The sky is speaking. It grumbles and rumbles and crackles, squealing with rage like a toddler unable to get its way. Then finally it breaks like the thunder that accompanies it, the rain crashed to earth and splatters the floor. Luckily, I am done for the day. For some reason, it has been raining mainly in the afternoons. This is good news for me since the rain virtually shuts down vulture activity. As is I have time for my carcass experiments and transects in the morning and seem to get done just as the sky is threatening to fall. It is a hard rain and I sit outside under canvas surrounded by the droplets. Within seconds pools of mud form and I can only wonder what the roads will be like tomorrow. Oh my God, it is hailing!! I can’t believe it. At first, it looked like little frogs were jumping around magically erupting from the soil (which they are, one just joined me under the tent), but that was actually hail. I just got up and grabbed a piece to confirm and indeed, ice just fell from the sky in Africa. Be amazed! But now it is just raining again.Read more...
