Red-billed Spurfowl

Pternistis adspersus

A medium-sized, brown francolin that is finely barred on the belly, head, and back. It has a diagnostic broad yellow eyering and reddish bill and feet. The juvenile has a reduced eyering and diffuse barring. The harsh, crowing, territorial call given from a low perch (“chak, chak, chak, CHAK, chakitty, chakitty”) is gruffer and lower-pitched than those of other francolins in its range. Natal Francolin differs by having scaled (not barred) underparts and lacking an eyering. Swainson’s Francolin differs by lacking barring and having red facial skin and dark blackish legs.

The red-billed spurfowl was described in 1838 by the English naturalist George Robert Waterhouse from specimens collected by James Edward Alexander on his expedition to Namaqualand and Damaraland. Waterhouse coined the binomial name Francolinus adspersus and noted that the specimens had come near the Fish River in what is now Namibia. The specific epithet adspersus is Latin for "sprinkling". The species is now placed in the genus Pternistis that was introduced by the German naturalist Johann Georg Wagler in 1832. The red-billed spurfowl is considered as monotypic: the proposed subspecies mesicus is not recognised.

Botaurus eurhythmus

Small heron, usually found in reed beds, expansive marshes, and rice fields; can occasionally be found in parks with sheltered areas, particularly lotus ponds and shaded pools. Generally uncommon throughout its range; never in the high densities of Yellow Bittern. Male is smartly attired, with a black cap, brown back, and a white neck and breast with a dark line extending down from the throat. Female is darker, with fine white spotting on the back and pale brown streaks on the throat. Compare with Cinnamon Bittern. Males give a gruff “roof, roof, roof” on the breeding grounds.

Oreotrochilus leucopleurus

Small hummingbird of the Andes from southern Bolivia through Argentina into central Chile; found in rocky and shrubby valleys, villages, and any open or semiopen areas with flowers. Often builds nest under eaves of buildings or bridges: a bulky cup of plant material and wool to insulate against cold nights. Fairly common. Readily identified in most of range by extensively white tail. Male has an emerald green gorget and a broad blue-black stripe on belly. Female is rather drab, but note slightly decurved bill, spotted throat, and tail pattern.

Utupua Whistler

Utupua Whistler

Pachycephala utupuae

Brightly-colored male has a bright golden belly, a black chest band and head, and a clean white throat. He appears to have a black “shawl” with golden wings and a black tail. Female is considerably duller, being olive-brownish above and yellow below, with a pale throat and brown breast. Endemic to Utupua, in the southeastern Solomons, where it is found in most island habitats, though avoids villages. Voice includes a sequence of sparsely spaced, thin, uninspired whistles. Formerly grouped with Vanikoro Whistler and Nendo Whistler under “Temotu Whistler.”
