White-fronted Swift

An eye-catching waterbird found on lakes and ponds with extensive floating vegetation. Long-tailed breeding adults are striking: the large white wing patch and head contrast sharply with its black body and bright yellow neck patch. Short-tailed wintering adults and juveniles have a brown back, white underparts, and a toned-down version of the breeder's head pattern. Vocalizations include a variety of nasal clucking and purring calls; song, seldom heard, a repeated, ringing “ku-woo.”

Very small owl of desert and western foothills of the Andes; no other pygmy-owl in its range. Overall plumage tones vary from brown to gray-brown, rarely rusty brown. Often active in daytime. Fairly common but easily overlooked, although persistent tooting song and presence of mobbing small birds can draw attention. Found in woodlands, hedges with taller trees, gardens, and locally in more open country. Ranges low to high, from canopy of tallest trees to low in thickets; sometimes perches on roadside wires.

Small black-and-white honeyeater found in drier woodlands of northern tropical Australia. Black above, white below, with neat white cheeks and black breast band. Nonbreeding adult has brownish back. Immature has yellow cheeks and brown upperparts. Juvenile similar but even paler brown and has very indistinct breast band.
