SCIENTIFIC NAME:Antilophia bokermanni POPULATION: About 800 adults IUCN STATUS: Critically Endangered TREND: Decreasing HABITAT: Lower and middle levels of tall, humid forest, with an abundance of vines.
The Araripe Manakin’s Critically Endangered status, which has led to its listing as anAlliance for Zero Extinction(AZE) species, has also focused attention on the importance of conserving its unique habitat. This habitat determines not only this bird’s continued survival but also the quality of life for thousands of people living in this largely impoverished region of northeastern Brazil.
Both bird and habitat are threatened by the clearing of forests for farming, cattle, and home-building.

BIRD OF THE WEEK
Like so many island species, the ‘I’iwi is beautifully adapted to the plants that share its evolutionary history. Its long, downward-curving bill is specialized for sipping nectar from tubular flowers.
ABC’s Hawai’i Programis working with the Hawai’i Division of Forestry and Wildlife and other partners on forest restoration projects — including the species’ preferred ‘ohi’a, koa, and mamane trees — on the Big Island and Maui. These projects improve habitat conditions for ‘I’iwi and other threatened forest birds, such asPalilaandMaui Parrotbill.
POPULATION: Estimates vary widely, from 190 to 260 million
HABITAT: Breeds in high-elevation conifer and mixed woods. Winters in fields, parks, and yard.
All Dark-eyed Juncos have some features in common: white outer tail feathers that are especially conspicuous when the bird takes flight; darker upperparts contrasting a lighter belly; and a pale bill. But this bird can vary drastically in appearance depending on where one sees it. Some juncos have more reddish-brown on the back and sides, some sport a contrasting dark hood over the head and neck, and others show a gray-tinged belly or white bars on the wings.
Although initially lumped with the rest of the Dark-eyed group, the endemic Guadalupe Junco was again split into a distinct species in 2016. Another closely related species, the Yellow-eyed Junco, is resident in pine-oak highlands from southeastern Arizona and southwestern New Mexico south through Mexican highlands to Guatemala.

BIRD OF THE WEEK
SCIENTIFIC NAME:Passerina cyanea
POPULATION: 78 million
HABITAT: Shrubby areas such as old fields, hedgerows, and forest edges.
A male Indigo Bunting in breeding plumage is a glorious symphony of shimmering blues, turquoises, and purples. But these beautiful colors are illusory.
Bunting owes its glorious appearance to an optical trick — the diffraction of light through its feathers. In poor lighting, the bunting’s glorious colors disappear and it becomes a plain, dark-colored finch.
But Indigo Buntings are more than a treat for the eyes — this species also helped reveal some important secrets about how birds migrate.
