The Antioquia bushhammer ( Atlapetes blancae ) is a little researched songbird species from the genus of the bushhammer ( Atlapetes ). It is endemic to the Colombian state of Antioquia and was only described in 2007 on the basis of three museum specimens. The type epithet honors the Colombian lepidopterologist Blanca Huertas, the partner of the first descriptor Thomas M. Donegan. On the other hand, blancae refers to the light underside.
features
The largest captured specimen of the Antioquia bushhammer measures 17 cm. The back and the upper tail covers are slate gray. The hand and arm wings are darker soot gray. A black face mask runs from in front of the eyes to behind the ear covers. The forehead, crown and neck are bright red. The underside is light. The streak of beard is dark, indistinct and fine. The middle hand wings show a small white wing field at the base. In the juvenile birds the wing field is missing and the plumage shows brown tones everywhere. The Antioquia bushhammer differs from the yellow-breasted bushhammer ( Atlapetes latinuchus ) by its bright red hood, by the smaller wing field, by the grayer instead of the black back and by the grayer instead of the yellow underside. It differs from the gray-breasted bushhammer ( Atlapetes schistaceus ) by the more intense red colored crown, by the smaller wing field, by the lighter underside and by the lack of a distinctive beard or a strong demarcation between throat and chest.
Discovery and Status
Until 2018, the Antioquia bushhammer was only known from three bellows, which come from three different museum collections and were previously incorrectly labeled as Atlapetes schistaceus . The holotype comes from a collection by Hermano Daniel from La Lana near San Pedro de los Milagros. Neither the sex of the bird nor the date of collection are indicated on the label. The first paratype is an adult male, also collected in La Lana in 1971 by Hermano Marco Antonio Serna . The second paratype is a juvenile specimen for which neither the place of discovery, nor the collector or the date of collection is given. During expeditions in La Lana in 2007 and 2008 Thomas M. Donegan could not rediscover this species. In January 2018, the Colombian ornithologist Rodolfo Correa Peña succeeded in rediscovering it near the municipality of San Pedro de los Milagros . It is believed that fewer than 20 Antioquia bushhammer are likely to exist. The main threat is the conversion of forest areas into pastureland or into cultivation areas for flowers. After the Antioquia bushhammer was recognized as a valid taxon by the South American Classification Committee in 2008, BirdLife International added it to the list of critically endangered bird species in 2009.
