Western Kingbird
Tyrannus verticalis
Fairly large yellow-bellied flycatcher; common and widespread in western North America. Rather pale gray head with weakly contrasting whitish throat and breast, and lemon-yellow belly. Also look for black tail with white edges (but this can be difficult to see, especially when worn). Found in open habitats with tall shrubs and trees, often perched up conspicuously on a telephone wire or fence post. Compare especially with Cassin’s Kingbird, which is darker and more contrasting on the head. Winters in large numbers south to Costa Rica, often gathering in large loose groups during migration.
Identification
Adults are a combination of both gray and yellow plumage, along with crimson feathers that are hidden until courtship or against intruders. Characteristic of kingbird species, the western kingbird is very territorial. Although the western is often misidentified as Cassin's kingbird, Couch's kingbird, or the tropical kingbird due to the yellow coloration, it can be distinguished from these other species through its black, squared tail with white edges.

Range and habitat
The breeding habitat is open areas in western North America. The increased presence of trees throughout the Great Plains during the past century due to fire suppression and tree planting facilitated the range expansion of the western kingbird, as well as range expansions of many other species of birds.

Behavior
The name kingbird is derived from their "take-charge" behavior. These birds aggressively defend their territory, even against much larger birds such as hawks. They will attack humans, livestock, and pets when they think their young are in danger. Kingbirds make a sturdy cup nest in a tree or shrub, sometimes on top of a pole or other man-made structure. Three to five white, creamy, or pinkish eggs with heavy blotches of brown, black, or lavender are laid and incubated for 12 to 14 days. Due to the small size of the nest, and the chicks' rapid rate of growth, most of them are pushed out of the nest, due to overcrowding, before they are fully feathered and able to fly. <p>They wait on an open perch and fly out to catch insects such as bees, robber flies, winged ants, grasshoppers, and spiders. They are also known to eat berries, buckthorn/sumac, and poison ivy seeds.<p>These birds migrate in flocks to Florida and the Pacific coast of southern Mexico and Central America.

Pygmy Cupwing
Pnoepyga pusilla
Essentially a tiny brown tennis ball supported by tiny chopsticks. Dark brown above with densely packed black-and-white scaling on the underside. Gives the impression of a tailless rodent as it makes its way furtively through dense shrubbery and leaf litter. Can be quite vocal and is jarringly loud for its size, giving single well-spaced piercing whistles on different high pitches, and occasionally an accelerating, usually rising rapid series of whistles. Also gives a sharp chip.
Sclater's Whistler
Pachycephala soror
A medium-sized bird of mid-montane forest. Yellow belly, olive back and white throat. Male has a black head and border to the throat. Female has a brown head and diffuse olive chest band. The male is similar to several other golden whistlers but lacks the yellow patch behind the head. Female is similar to Regent, Lorentz’s and Vogelkop Whistler’s but has white throat and brown head. Voice, a series of typical whistlerlike “chew!” or “whip!” notes that get louder and end with an explosive quality.
Crimson-crowned Flowerpecker
Dicaeum nehrkorni
A tiny, short-tailed songbird. Unmistakable male is dark with a red cap, breast spot, and rump. Underparts white, with a dark vertical line on the belly and white tufts on sides of breast. Female is gray, with red confined to rump; this color patterning is diagnostic. Juvenile resembles female, but lacks the red rump. Singles or pairs inhabit the upper reaches of hill and montane forest and forest edges. Restricted to Sulawesi. Gives thin, high-pitched “tzeet” and “kwit” call notes. Song starts with “tzeet-tzeet” phrases, then descends into a rapid warble.
