I've been sent this picture and asked to submit it to the forum as it's causing some debate here. Seen inland in Gambia. Comments?
The sinclair and Ryan book clearly shows female Diderick with a buffy throat like this bird and says often shows this. Also you can see white spots on the wings which really does eliminate the two others.
Would you be interested in this photo, which is of the rufous juvenile form of Dideric Cuckoo, which also doesn't seem to be in the Opus or Gallery? I only saw this juvenile and not either of the adult forms.
This bird's name rarely seems to be spelt the same way twice. Opus has gone for Dideric. Wikipedia gives this and Didric. Zimmerman et al. Birds of Kenya and Stevenson and Fanshawe Birds of East Africa both go for Diederik. Some posters here have gone for Diderick. When I tried to search on Opus, only Dideric would work. Why is there no agreed spelling?
Incidentally, Zimmerman et al. Birds of Kenya and Stevenson and Fanshawe Birds of East Africa also have dramatically different pictures for the female: the former a green bird like the male with a rufous tint, the latter a rufous bird with a very slight green tint!
I uploaded my photo to the gallery as Niels suggested.
The gallery space readings don't seem to be right. The 'disk space used reading' seems to be the byte count with a kb suffix (and then repeated in brackets correctly with bytes).
