About Crithagra mozambica (P.L.Statius Müller, 1776)
The yellow-fronted canary, scientifically named Crithagra mozambica, is a small passerine bird that belongs to the finch family. In aviculture, it is sometimes called the green singing finch or the green singer. This species is a permanent resident breeder across Africa located south of the Sahara Desert. It inhabits open woodland and agricultural areas. It builds compact cup-shaped nests in trees, where it lays three or four eggs per clutch. The yellow-fronted canary has been introduced to multiple locations outside its native range: Mauritius, Rodrigues, Réunion, Assumption Island, Mafia Island, Puerto Rico, and the Hawaiian Islands. Within the Hawaiian Islands, it occurs on western Hawaii, southeastern Oahu, and Molokai. This is a common, gregarious seedeating bird. It measures 11 to 13 centimeters in total length. Adult males have a green back, brown wings, and a brown tail. Their underparts and rump are yellow, and their heads are yellow with a grey crown and nape, plus a distinct black malar stripe. Females have a similar overall appearance, but their head patterning is weaker and their underparts are duller in color. Juveniles are greyer than females, particularly on the head. The song of the yellow-fronted canary is a warbled zee-zeree-chereeo.
