Southern Silvery-Kingfisher
Ceyx argentatus
A small, dashing kingfisher of forested lowland and foothill streams and ponds on Mindanao and neighboring islands. Overall dark blue in color, slightly paler below, with a white throat and belly, a white patch behind the cheek, and a white spot behind the nostril. Note the pale silvery-blue stripe down the back to the tail, the whitish flecks on the head and wing, and the bright red legs. Unmistakable. Voice is a simple, high-pitched “tseep,” often given in flight.

分布与栖息地
It appears to be reliant upon forested streams below 1,000 m and will tolerate secondary and selectively logged forest and even streamside vegetation within coconut plantations, close to forest edge.<p>IUCN has assessed this bird as near threatened with the population being estimated at 1,500 to 7,000 mature individuals. This species' main threat is habitat loss with wholesale clearance of forest habitats as a result of logging, agricultural conversion and mining activities occurring within the range.<p>Extensive lowland deforestation throughout its range is the chief threat. Most remaining lowland forest is leased to logging concessions or mining applications. Watercourses with high siltation loads, resulting from deforestation, appear not to hold the species, and riverine pollution is likely to have a similar impact. Forest at Bislig (Mindanao) is being cleared under concession and re-planted with exotic trees for paper production. Conversion of terminalia forest into rice fields and oil palm plantation is driving habitat loss elsewhere.

Black-capped Gnatcatcher
Polioptila nigriceps
Long-tailed little bird of dry forest and scrub in northwest Mexico. Found as singles, pairs, or family groups, usually foraging at low to middle levels. Breeding plumage male (March–August) has black cap, but other plumages very similar to Blue-gray Gnatcatcher, a common migrant throughout the range of Black-capped. These species best separated by call note: Black-capped has lower and rougher call than mew of Blue-gray. Also note Blue-gray often has a pinkish base to its smaller bill (gray on Black-capped), a more distinct white eyering (face a little more "open" on Black-capped), and a shorter, less strongly graduated tail.
Steel-blue Whydah
Vidua hypocherina
A nest parasite that lays its eggs in the nests of Black-cheeked and Black-faced Waxbills. As with other whydahs, breeding males are distinctive, whereas non-breeding males and females are drab and inconspicuous. Breeding males are glossy blue-black with elongated central tail feathers. Non-breeding males and females have a brownish back, a heavily striped face, and a whitish bill and legs. Generally uncommon in rather dry savanna and woodland. Non-breeding male and female can be cautiously separated from other whydahs and indigobirds by their pale bill and legs. Not very vocal, but does imitate the waxbills that it parasitizes.
Black Swan
Cygnus atratus
Unmistakable large black swan with a red bill. When swimming this species is almost entirely black. Wings show extensive white flight feathers when flying. Juveniles are similar but dark-gray. In Australia, compare with Magpie Goose, which has white belly, and white underwing with black tips. Typically found along inland waterways, rivers, sewage ponds, and coastal lagoons and inlets. Sometimes flocks together in enormous numbers on large wetlands.
