Birdfinding.info ⇒  The western form of Yellow-crowned Bishop is uncommon and localized in West African wetlands.  Areas where it is locally numerous include the Senegal and Gambia River bottomlands and Mole National Park in Ghana.  The introduced Iberian population is expanding and can be seen at many locations, most readily at the Estuário do Tejo Nature Reserve and Vila Franca de Xira near Lisbon.  In Puerto Rico, consistent sites include the Caño Tiburones Natural Reserve, the Barceloneta rice fields, and the ponds along Coco Beach Boulevard in Río Grande.  The tiny Jamaican population persists mainly at the Portmore Sewage Ponds near Hellshire.

“Yellow-chested Bishop”

Euplectes afer afer

Family: Ploceidae

Western and central Africa.

Patchily distributed in marshes and humid grasslands of the Sahel and tropical western Africa from Senegal and southern Mauritania east to southwestern Sudan and locally south into central Africa to northwestern Angola and western and northern portions of the Democratic Republic of the Congo.

An introduced population is well-established on the Iberian Peninsula in Portugal and southwestern Spain, and appears to be expanding north and east, especially along the coasts, into France.

Another apparently well-established population exists on Puerto Rico, in wetlands along the northern coast from Caño Tiburones to Río Grande.

Smaller introduced populations are more tenuously established in Jamaica (localized on the west side of Kingston), the United Arab Emirates (Dubai to Fujairah), and possibly also in Kuwait.

Identification

Males in breeding plumage are unique and unmistakable: bright-yellow on the upperparts, chest, and undertail, with a black face, wings, and belly.

When displaying, the male puffs out its plumage, at times appearing almost spherical.  When raised, the long yellow feathers on its back take on the appearance of big yellow backpack.

Females and males in basic plumage are sparrow-like, with heavily streaked brown upperparts and lightly-streaked pale underparts.

The facial markings are strong: a bold buffy or yellowish eyebrow contrast with a thinner, but pronounced, dark eyeline, both extending far behind the eye.  The crown is blackish with fine pale streaks.

Voice.  The calls of the “Yellow-chested Bishop” are structurally similar to the calls of “Yellow-crowned”, but are gentler, more musical, less harsh and percussive.  In breeding display, males alternate between rapid twittering and brief chirps: Another song is an evenly paced series of soft buzz notes, followed by a twitter:Typical contact calls are squeaky chirps:

Notes

Monotypic form, one of two distinct forms of Yellow-crowned Bishop (afer).
