I'm curious as to the Little Grey Greenbul though. Having listened to many hours of audio from Kakamega, as well as a good deal of field obs too, I firmly believe this species does not occur in Kakamega, if it ever did.
It seems the field characteristics for separation from Ansorge's are thin at best, and the rattle call attributed to the species on the EA App actually belongs to Ansorge's. Several times I've watched an Ansorge's sing, only to then give that same rattle call. This was also the finding of Caroline McBride in recordings on the Macaulay Library, and her ear is almost second to none. The birds fast jerky song with ascending terminal note is absent from the Kakamega soundscape. Incidentally, the rattle call also does not sound like the bird in West Africa. That Dale Zimmerman was unable to find any clear ecological segregation between the presumed two forms is another nail in the coffin for me.
Can anyone provide definitive evidence that Little Grey occurs in Kakmega? Where are the purported old specimens?
Best Wishes, James
