Bannerman's Shearwater

Puffinus bannermani

A small black-and-white shearwater with relatively broad wings and a long rounded tail. Underwing very white, contrasting with darker smudgy marks along the leading edge of the wing. Two dark smudge marks are often visible at the collar, extending down from the hood. Somewhat similar to Bryan’s Shearwater, but much larger, and white does not extend above the eye, creating a darker-faced appearance. Also lacks the distinctive rapidly fluttering flight of Bryan’s.

Slate-throated Redstart

Slate-throated Redstart

Myioborus miniatus

Active and attractive warbler of highlands and foothills. Sexes look alike: head and upperparts slaty gray with blacker face and small rusty cap. Belly is red in Mexico, orange-red in northern Central America, and yellow from Costa Rica to South America. White-tipped tail is usually fanned and flapped side-to-side. Favors evergreen and pine-oak forest and edge, and cloud forest in the Andes. Usually in pairs, foraging mainly at low to middle levels, at times even on the ground. Frequently joins mixed-species feeding flocks.

Barred Fruiteater

Barred Fruiteater

Pipreola arcuata

Chunky, short-tailed, flat-headed bird patterned in green and black. Male has black head and breast, pale yellow belly with bold dark barring, and mossy green upperparts with bold pale spotting on the wing. Female is similar but has a green head with barring all the way up the throat. On both sexes, note red bill and legs and pale eye varying from orange to gray to whitish. Fairly common in stunted forested habitats in the upper subtropical and temperate zone in the Andes. Sluggish; perches quietly in the middle levels of the forest, sometimes following a mixed-species flock. May be seen singly or in pairs, but several can gather around a fruiting tree. Listen for super high-pitched calls.

Gilded Flicker

Gilded Flicker

Colaptes chrysoides

Large woodpecker, very similar to Northern Flicker. Overall pale sandy brown with gray face and brown crown. Spotted below with black oval on chest. Underwing and shafts of flight feathers bright yellow. Males have red mustache stripe; sexes otherwise alike. Combination of face pattern and yellow in wings helps distinguish from both "Red-shafted" and "Yellow-shafted" Northern Flickers. Shows a strong affinity for saguaro cactus but also found in nearby woodland. Gives a piercing "kleer" call similar to Northern Flicker.
