[QUOTE="Brian J Small, post: 1745314, member: 51278"] Toy A very good photo. I got out my museum notes for my illustrations in the East African guide to double check the features for these quite similar species. Female/immature Emerald Cuckoo has broad (bronze-) greenish bars on the underparts, distributed densely down to the vent; immature Klaas's has narrower bars, sometimes on a buff or off-white background. The post-ocular spot on Klaas's can be well hidden by barring, but on Emerald there should be no white at all behind the eye. Based on my museum notes and photos - illustrations in the EA guide - and on the fact that Emerald is really quite rare in the Gambia (I have not seen one in ten visits), I would go for Klaas's Cuckoo for both images.
