I took this photo about 10 days ago in the Bafut-Nguemba forest reserve above Lake Awing, near Bamenda, southwest Cameroon, at an altitude of about 2000 meters. The best I can come up with is an immature Wahlberg's Honeybird (Prodotiscus regulus), but this was my first African trip so I have precious little experience. Any help would be very useful!
