River Tern
Sterna aurantia
Widespread inland tern of South and mainland Southeast Asia. Breeding adults have full black cap and pale gray wings; white belly, larger size, and heavier structure distinguishes this species from the less common Black-bellied Tern where their breeding ranges overlap. Non-breeding adult has patchy black on the head instead of a full cap, and juvenile has mottled brownish-gray back with a partial black “mask”. Favors freshwater sites, breeding on sandy islands. Gives a grating “kYYEER” note.

Philippine Drongo-Cuckoo
Surniculus velutinus
A slender, medium-sized bird of lowland and foothill forest. Entirely black with glossiness in the wing and in the slightly flared tail. Forages for insects in the forest canopy. Resembles Balicassiao and Hair-crested Drongos, but smaller, with a thinner bill and no fork in the tail. Song is a steadily rising series of whistled notes.
Rufous-collared Sparrow
Zonotrichia capensis
Handsomely patterned sparrow from highlands of Chiapas south to temperate South America. Occurs in open and semiopen habitats such as villages, towns, and farmland with hedges and brushy thickets. Feeds on the ground and in bushes, at times in flocks. Note the peaked crown, bold black-and-gray head pattern (though black much reduced in southern populations), bright rusty collar, and black chest patch. Juvenile has ghosting of adult pattern and breast is streaked dusky.
Red Shoveler
Spatula platalea
Distinctive dabbling duck: combination of very large, slightly shovel-shaped black bill and and pale blue forewing patches (brighter on male) identify all plumages. Male has a pale gray head with pale yellow eyes and a “red” body with black spots. Female is mottled brown overall, but note white sides to pointed tail, big black bill. Fairly common in wetlands and at lakes, river mouths, and sewage lagoons. Unlike many dabbling ducks, often rather quiet.
