Woodpecker Finch
Camarhynchus pallidus
A drab Galápagos finch with a stretched-out-looking bill. It has tan upperparts and pale whitish or yellowish underparts that may have a small amount of streaking. A small number of birds on San Cristóbal have dark hoods. Stout and elongated bill is pure black on breeding male, partly black on non-breeding male, and pale orange on female. Best identified by bill shape and behavior. It creeps along branches peering around for and probing into cavities, and it sometimes taps like a woodpecker. One of very few tool-using animals, it uses twigs and thorns to extract prey from holes in branches. Found on most islands but absent from Española, Genovesa, Marchena, Pinta, Darwin, and Wolf.

分布与栖息地
Woodpecker finches are native to the Galapagos Islands. They are commonly found on the islands of Isabela, Santa Cruz, San Cristobal, Fernandina, Santiago, and Penzón. They occupy all areas of the islands, from the most arid zones to more humid zones. However, the density of woodpecker finches is greater in the more humid zones than in the drier ones. Woodpecker finches are also found at a variety of altitudes, from sea level to higher inland elevations. They are a not a migratory species and when they do fly, they only fly short distances.

Fawn-breasted Tanager
Pipraeidea melanonota
Small sleek tanager with distinctive color pattern: pale sandy underparts with peachy blush on breast, black mask, powdery-blue crown, and darker blue back and wings. Sexes alike. Uncommon in second growth, edges, and gardens, where it is most often seen singly or in pairs. Occasionally follows mixed-species flocks. Found from foothills to upper subtropical zone in Andes, sometimes straying even higher. Populations in southeastern South America occur at lower elevations.

White-eared Ground-Sparrow
Melozone leucotis
Strikingly patterned large sparrow, found locally in foothills and highlands of Chiapas and Central America. Favors tropical and subtropical forests, shade-coffee plantations, and brushy edges. Typically on or near the ground in shady understory, where quite timid; often in pairs. Striking head pattern is unlike other species in the region, with big white face spots and yellow neck patch. Populations from Nicaragua south have more black on face and breast.

Cinnamon Bittern
Botaurus cinnamomeus
Small heron of wet and open grassy areas such as flooded meadows and paddy fields. Uniformly bright rufous upperparts of adult male unmistakable. Female and juvenile have pale streaked belly, dark streaks and spots scattered on the wings and back, and are dark brown with some rufous tones above. Females often have light spotting on the wings, potentially causing confusion with female Schrenck's Bittern, which has brighter and more solid white spots and a prominent dark crown lacking in Cinnamon. Gives dry croaking clicks.
