Olive-crowned Yellowthroat

Little bright yellow bird found in southern Borneo and northern Java. Entirely yellow coloration (no dark lores or gray belly) distinguishes this species from other white-eyes within its range. A coastal forest specialist, found in coastal scrub forest, mangroves, and forest edge, as well as adjacent gardens and plantations, where it often visits planted langsat (or duku) trees. Often found on small offshore islands. Forages actively in the canopy, giving quiet tweeting and cheeping calls; unlike other white-eyes, not a strong songster. Declining across much of range due to habitat destruction and fragmentation.

Fairly large, chunky, and often conspicuous wren of drier foothills and mountains; endemic. Mainly in areas with pine-oak and oak woodland and scrub; often around villages and ranches, clambering on stone walls and even entering houses. Usually in small social groups, which can be confiding. No similar-looking species occur in its range. Note the black whisker, band of black spots across the breast, and complex patterning on the back, wings, and tail.

Fairly large hummingbird of brushy woodland, edge and semiopen areas with flowering trees, mainly in drier habitats in southwestern Mexico and neighboring Guatemala. Feeds mainly at middle to upper levels in trees. Combination of bright white underparts (throat sometimes stained yellow by pollen) and bright red bill with black tip are distinctive. Male and female similar, but male has a more coppery, less greenish tail. The crown is deep green, unlike similar Violet-crowned Hummingbird, which occurs to the north of Green-fronted.
