Mangrove Finch

Camarhynchus heliobates

A critically endangered Galápagos finch and one of the world’s rarest birds. Currently known only from mangroves at a few sites (with restricted access) on Isabela. Formerly found on Fernandina, but there are no recent substantiated records there. Both sexes typically have brown upperparts, whitish underparts with tan streaking, and a faint eyebrow. Some older males may have a faint, dark hood. Bill is relatively long, with a curved upper edge and mostly straight lower edge. Male’s bill is black when breeding and slightly paler at other times. Female’s bill is orange. Similar to Woodpecker Finch, but that species has a longer bill and less prominent streaking.

分布与栖息地

As its name suggests, the mangrove finch lives in the mangroves of the Galápagos Islands. The mangrove finch feeds upon the various insects, larvae, spiders, and vegetable matter found in the mangroves. It closely resembles the far commoner woodpecker finch, but is not known to use tools.

保护状况

The mangrove finch is classified as critically endangered on the IUCN Red List, with only 20–40 mature individuals as of 2021.<p>In January 2014, project researchers reported successfully raising 15 mangrove finch chicks in captivity and releasing them back into the wild. Since then, 36 fledglings have been "head-started" and the project is building on this success.<p>The Mangrove Finch Project is a bi-institutional project carried out by the Charles Darwin Foundation and Galapagos National Park in collaboration with San Diego Zoo Global and Durrell Wildlife Conservation Trust. The project is supported by the Galapagos Conservation Trust, the Mohamed bin Zayed Species Conservation Fund, Durrell Wildlife Conservation Trust, The Leona M. and Harry B. Helmsley Charitable Trust, Galapagos Conservancy, and the British Embassy in Ecuador.

Eyebrowed Wren-Babbler

Eyebrowed Wren-Babbler

Napothera epilepidota

While furtive, this tiny skulker is distinctive if seen well. Short-tailed and large-headed in profile, somewhat like a vole or shrew. Brown with a pale throat, white eyebrow, and white speckling on the upper body. Both undersides and uppersides are streaked with white, though the prominence of this streaking depends on the lighting. Appearance varies slightly across range. Song, composed of a single airy monotone or slightly falling whistle repeated at 3- to 5-second intervals, is hauntingly ventriloquial. Found in tropical and subtropical evergreen forests with dense understoreys, from lowlands up into submontane areas.

Buff-breasted Babbler

Buff-breasted Babbler

Pellorneum tickelli

Rather graceful-looking brown babbler with a long tail and long legs. Averages paler below than above, but generally unmarked. Inhabits foothill forests with dense undergrowth, where it forages close to or on the ground. Almost completely unmarked appearance distinguishes it from most other babblers in range. Listen for its loud, strident song, a repetitive “wit-wee, wit-wee, wit-wee.” Calls include rattling trills, a harsh descending laugh, and sharp single notes.

Spot-breasted Wren

Spot-breasted Wren

Pheugopedius maculipectus

Small, skulking wren of vine tangles and thickets in tropical lowlands. Like most wrens, heard far more often than seen. Rollicking, ‘happy,’ whistled song is a duet between male and female, keeping them in touch with each other. Rising call note sounds like a finger run along a comb. Plumage is rich rusty brown overall, with white eyebrow and dense black spotting on whitish breast.
