Right in front of our tent at Savuti, facing a fairly narrow section of the now dry Savuti Channel, animals would troop by in long lines going to the water hole, principally zebra, impala and baboons.  After they went by, the cattle egrets would fly in to get the disturbed insects.

They would light, eat a while and then fly off again to the next buggy place.

This is a fork-tailed drongo.  They are the only all black perching bird and are known for their feistiness--they will attack any bird that comes in their territory, even an eagle, which is very brave for such a small guy - 6 inches/15cm.

I never did get a good view of the forked tail to show you--they are very busy birds, chasing potential enemies, dashing out for bugs--those little whiskers around the bill help catch insects.  I think he sees one now!

I should have put the kori bustard in the large bird letter.  You can see he is big even next to an impala.  They are the heaviest flying bird there is.  Like the marabou stork, they have a breeding pouch on their neck which they can inflate, but because it's covered with feathers, it makes all the feathers stick way out in front of the neck and he struts around showing this off.  I've seen this display once.

This is a red-billed oxpecker and there on the lower part of the giraffe's neck is a wound that the oxpecker has cleaned.  They eat ticks and insects off the animals, but they also like to clean wounds and often keep at it so that it won't heal rapidly.  Some say they prevent infection too though, so it's a toss up.
