In the past at the peak of the migration, this fields would have been covered with large numbers of wildebeest and zebras moving in unison towards the Mara River. The herds would congregate at the edge of the river, hesitate, and all of the sudden jump into the river where crocodiles were waiting for their meals. I was not able to photograph what I call the "Greatest Nature's Show on Earth" this year.
But the predators were there as always waiting for the arrival of the herds. Lions are at the top of the food chain in the Masai Mara/Serengeti ecosystem in East Africa ( Kenya and Tanzania).
I have observed these cats sitting in rocks and hills scanning the horizon for the arrival of the herds.
In May of 2007 I was in the Western Serengeti near the Retima River (Tanzania) awaiting for the arrival of the herds. It was amazing to watch the lions sitting on top of the Kopjes scanning the horizon. As soon as they saw the arriving animals, they would climb down off the rocks and head for the herds to get their meals. A whole pride including cubs would move together.
As is well known, these cats work in teams and the females are usually the ones who lead the hunting parties. For what I have observed in the past, there seems to be female leader who starts the hunt and will instigate the others into following her to the hunt. These are elaborate and include the setting of traps. Some of the cats will hide in strategic locations and the others will drive the prey in their direction. I have also witnessed what I call relays where one cat will start a chase and direct the prey into others that have previously positioned themselves.
Not all chases are successful and when this happens, the cubs left behind, usually with an adult nanny for protection , will reunite with the hunting party and are greeted by their moms with licking and rubbing of faces.
Lions spent most of the time sleeping and looking after the cubs who frequently interrupt the adults sleep. Most prides have an adult male that service and protect the females and his cubs from other males that would try to take over the family. He usually is not active in the hunts but is the first to the banquet. Other adult male lions live solitary lives or with brothers. But when it comes to taking over a pride or mating, all brotherhood sharing is forgotten.
The leopard is the major trophy of any safari due to their shyness an difficulty in photographing. This is the only one I got to photograph but able to get great images; he stayed in the tree all the time. He had killed an impala early in the morning and the carcass was hanging from a nearby tree. In 2007 while in the Serengeti I got to see 11 leopards--very unusual--but I was not able to approach them due to park rules that does not allow for of-the-road-traffic.
