This area contains one of the highest concentrations of range-restricted species in the world. No fewer than 60 endemic species depend on the region’s wet forests. Among the birds recorded at the Tanagers Reserve are globally threatened species such as the Choco Vireo and Gold-ringed Tanager, both Endangered; and the Cloud-forest Pygmy-owl, Black-and-gold Tanager, and Giant Antpitta, all of which are Vulnerable.
Golden-winged Warblers are specialists, requiring “young,” or early-successional, forests for breeding. Once their young leave the nest, the birds need mature forests for foraging nearby.
Golden-winged Warblers also suffer from competition and hybridization with Blue-winged Warblers; parasitism by cowbirds, which lay their eggs in the warbler’s nests; and loss of wintering habitat in Latin America.
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.
PLANET EARTH BIRD WORLD has over 1,500 members and over 99,000 photos and videos.
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.
