A large flock of Pelicans were seen in the early morning 

 on the tops of some high trees by the Tsavo. The river was 

 enclosed by bush at this point, and they could not have been 

 feeding anywhere near. I presume they were on migration 

 and had rested there for the night.

I noticed several White-faced Tree-Ducks among a large

This specimen was shot by the late R. B. Woosnam, who 

 was with me at the time.
