Leaf-love

A medium-sized bird of lowland forest canopy on Biak Island, in northwestern New Guinea. Male is black above and white below, with extensive white in the wing. Female is similar, but dark gray-brown above. Song is a steadily rising up-and-down series of hiccuping whistles: “wi’di-DEE, wi’di-DEE!”

A large, bulky, gray-brown ibis with an iridescent green-purple gloss on the wings. It has a bicolored black-and-red bill and a white streak across the cheek under the eye. Pairs and small flocks occur in a variety of habitats including open country, wetland margins, and forest edge; they forages on the ground, digging, probing soft soil, and picking up invertebrates with their long bills. The frequently-heard call is one of the most characteristic sounds of Africa: a loud, raucous, trumpeting “ha-da-da” which gives the bird its name.

One of a confusingly similar complex of species, this medium-sized warbler has a bright yellow eye-ring, a pale and indistinct wingbar, and a grayish crown bordered by two long black stripes. The weakness and greenish cast of the gray crown separates this species from various other “golden-spectacled”-type warblers, such as Gray-crowned. Golden-spectacled Warbler is very similar; in Whistler’s, look out for an unbroken eye-ring, a shorter bill, a longer tail, and slightly duller green upperparts. Whistler’s breeds in high-altitude temperate broadleaf forest from around 2000 meters up to the treeline; averages higher in altitudinal breeding preferences than Golden-spectacled Warbler. Like other “golden-spectacled”-type warblers, Whistler’s typically forages at lower and middle levels of forest, often mixing with other species and making flycatching sallies. Song consists of a 2- or 3-noted whistled phrase repeated 2-3 times without pause, lacking the trills of Golden-spectacled Warbler.
