Least Concern

Black-throated Toucanet (Aulacorhynchus atrogularis)


French: Toucanet à gorge noire German: Schwarzkinnarassari Spanish: Tucanete gorjinegro

Pteroglossus atrogularis

J. H. C. F. Sturm and J. W. Sturm#R

, 1841,

Chanchamayo, Andes of Peru


Until recently, considered conspecific with A. prasinus along with A. wagleri, A. caeruleogularis, A. albivitta and A. cyanolaemus, but differs from all taxa in the complex by virtue of its sharply demarcated black throat and subocular area (3); yellow upper and white lower “jaw-band” (line between face and bill), the yellow being distinctively different (noted on two specimen labels, and still visible on all skins) (2); yellow or white continuation of this jaw-band over the top of the bill, forming a distinctive pattern of yellow-black-yellow at the base of the culmen (2). Sometimes thought to include A. cyanolaemus as a race#R, but differs in characters enumerated under that species. Two subspecies currently recognized.

    Status and conservation

    Not globally threatened (Least Concern). Generally rare to uncommon in SE Peru, where c. 2 pairs/100 ha of transitional forest but fewer in more mature forest, and usually... read more
