Micronesian Myzomela
Myzomela rubratra
A tiny bright red myzomela with dark blackish wings and tail, a blackish patch in front of the eye, and a decurved bill. Found widely in most habitats, mostly along forest edge and in scrub. The only myzomela in Micronesia. Voice is a mix of wheezing upslurred whistles and complex chattering and squeaking.
识别特征
The Micronesian myzomela (Myzomela rubratra), also known as the Micronesian honeyeater, is a small honeyeater. It is found on the Caroline and Mariana islands, except on Guam, where it has been extinct since 1986. It occurs in and around the edges of forests, as well as coconut plantations, coastal strand, savanna brush, villages, towns, and gardens. Both genders have a predominantly black or brown body with scarlet-red patches—the location and coloration, however, varies widely by subspecies. When mature, the female, unlike the male, usually has olive fringing on her tail and wing feathers; additionally, the male does not have any brown on his body. Juveniles are much browner compared to adults and have little or no red coloring. The Micronesian myzomela has a unique song in the dawn—a continuous stream of trilled whistles and phrases, lasting for about 25 minutes on Kosrae, Yap, or Pohnpei, or a wheezy whistle on the Mariana Islands. Later in the day, the Kosrae bird produces a short, variable song and a wide array of "rather uninteresting" scolding or buzzy calls. On the Mariana Islands, the daytime song is a simple and tuneful "per-mit-you". The Palau bird's call is unique, resembling that of the great crested flycatcher or Micronesian starling. The Micronesian myzomela breeds year-round. Courtship behaviors are varied—grounded displays where pairs walk together along branches on Aguiguan; erratic aerial chases where the male chases the female, often touching wingtips on Guam. The nest is built low to the ground, in shrubs or small trees with thick foliage, often along woodland edges, open areas, or near residential buildings. It is cup-shaped, and may be composed of grasses and other plant fibers, often with a distinct inner lining. The nest measures between 50 to 85 mm in width and 20 to 70 mm in depth. It usually lays 1 to 2 eggs per clutch, which are glossy white to off-white with brown speckles, with dimensions of about 18.5 by 13.6 mm. Incubation is probably done solely by the female and takes 15 to 16 days. Hatchlings are altricial, fledging after two weeks.

Green-breasted Bushshrike
Malaconotus gladiator
A large, robust bushshrike with a massive head, a chunky hook-tipped black bill, and a pale eye; plumage is dull uniform olive, paler underneath, and head is gray. An uncommon resident endemic to the Cameroon-Nigeria highlands, found singly and in pairs in the canopy and at middle levels of primary hill and montane forest between 930 and 2300 meters of elevation, preferring steep slopes. Gives a low-pitched extended sorrowful “whhooooooo-lwe” song up to 10–15 times in succession, along with harsh clicks and rasps. Other similar large bushshrikes are yellow or orange underneath.
Anna's Hummingbird
Calypte anna
Relatively large-headed and chunky. Gray and green overall, lacking buffy or orangey tones. Males have shocking magenta head, which appears dark when not catching the light. Females have dingy grayish underparts and often show a dark patch in the center of the throat. Note relatively short, straight bill compared with Black-chinned or Costa’s Hummingbird. Common year-round in the Pacific states of the U.S., mainly in relatively open or scrubby habitats including desert scrub and chaparral. Frequently seen in suburban yards and gardens, often visiting sugar water feeders. Expanding its range northward into British Columbia, even regular in southeast Alaska. Winters to southern Baja and locally elsewhere in Mexico. Listen for male’s scratchy, metallic song, given when perched.
Olive Bee-eater
Merops superciliosus
Large green bee-eater with a rufous throat patch. Found in almost any open habitat, including savannah, cultivation, scrub, and grassland. Often perches up conspicuously, singly or in small groups. Feeds on insects on the wing, and often seen in flight, sometimes in loose flocks. Incessantly gives a soft rolling “krrrio” call, especially in flight. Similar in shape and size to European and Blue-cheeked Bee-eaters. Has a very different color scheme from European Bee-eater, and a subtly different one from Blue-cheeked: green underparts, bright white stripes on the cheek, and a brownish crown.
