Principe Sunbird Anabathmis hartlaubii

A medium-sized dark sunbird with a graduated, white-tipped tail. Male has a blue-purple iridescent throat and upper tail; female and juvenile are dull yellow underneath. A common endemic resident in almost all habitats across Príncipe, where pairs and small groups frequently join mixed-species flocks. Its distinctive rapid song and upslurred “tsoooeeet” call are characteristic sounds of the island. Dull Olive Sunbird has a longer and more recurved bill than Principe Sunbird.
