Gray-breasted Woodpecker

Melanerpes hypopolius

Fairly common endemic woodpecker in desert interior habitats of southwest Mexico, especially in areas with tall columnar cacti, including towns and villages. Often in pairs or small groups. Rather drab and grayish overall with a whitish forehead patch and a densely barred black-and-white back. Male has red crown patch and female has plain gray head. No similar species in its limited range.

识别特征

Like Gila woodpecker (male has round red crown patch), but pale red on cheek; short black line over eye; much darker and grayer below and on head. It is also similar to the zebra-backed birds of the same genus.

分布与栖息地

Areas of domain in Mexico include Guerrero, Morelos, and Puebla. Knowledge of the behavior of this bird was widely unknown before a 1990 study out of the Cooper Ornithological Society which observed six of the birds. The study confirmed the communal roosting habits of the birds, specifically on cacti. Its natural habitats are subtropical or tropical moist lowland forests and subtropical or tropical high-altitude shrubland.

Sooty Owl

Sooty Owl

Tyto tenebricosa

Medium-sized dark-gray owl with prominent facial disc and white speckles through the plumage. This handsome species inhabits rainforest, wet eucalypt forest, and surrounding habitats. Its pale feet seem too large for its body. The northern subspecies is smaller and paler. Main calls include a high-pitched "falling-bomb" whistle and insect-like squeaks and trills.

Bates's Sunbird

Bates's Sunbird

Cinnyris batesi

A very small nondescript sunbird with a short orange-based bill that curves uniformly along its length; easily mistaken for females of other sunbirds. The only features on the olive upperparts are indistinct paler eyebrows and lines running under the eyes, and yellow edging to the wings. Although often hidden, the male has yellow or whitish (not red) tufts at the shoulders. Singles are local and inconspicuous at the edges of lowland and riverine forest, sometimes entering secondary growth; it joins mixed-flocks and is frequently attracted to epiphytes in mossy clumps. Calls a high-pitched “tseeep” and trills. Little Green and Fraser’s sunbirds are similar to Bates’s but brighter, with straighter bills and more distinct yellowish eye-rings; Ursula’s Sunbird has a long decurved bill and grayish face and underparts.

Barau's Petrel

Barau's Petrel

Pterodroma baraui

A pale, mid-sized petrel with white underparts, dark cap, white forehead, and black margins to the white underwing. In flight, also note the distinctive, dark “M” on the gray upperparts. Easy, buoyant flight in calm weather, often gaining height and gliding down towards the ocean surface. Wheels high and steeply in strong weather.
