Abstract

Observations on nesting Beautiful Long-tailed Sunbirds Cinnyris pulchellus in The Gambia revealed that some females have dark or partially dark bibs, contrary to most accounts in the literature. Furthermore, all fledglings seen in The Gambia also had dark bibs and some males in eclipse plumage or lacking tail-streamers engaged in breeding activity. The conclusion that some adult female C. pulchellus have dark bibs and that some, probably all, juveniles have dark bibs was confirmed from museum specimens. It is further demonstrated, based on specimens, that some adult females and juveniles of Gorgeous Sunbird C. melanogastrus also have dark bibs.
