El tucanet gorjanegre (Aulacorhynchus atrogularis) és un ocell de la família dels ramfàstids (Ramphastidae) que habita els boscos dels Andes del nord i est de Perú, nord de Bolívia i sud-est d'Equador.
Aquest tucà es considerava conespecífica amb Aulacorhynchus prasinus fins que es va separar com una espècie de ple dret arran moderns estudis.[1] Ha estat dividit en tres subespècies:
L'última és considerada una espècie diferent per alguns autors [2] com tucanet becnegre (Aulacorhynchus cyanolaemus).

The black-throated toucanet (Aulacorhynchus atrogularis) is a near-passerine bird in the toucan family Ramphastidae. It is found in Bolivia, Brazil, Ecuador, and Peru.[2]
The black-throated toucanet was originally described in the genus Pteroglossus. What is now the black-throated toucanet was three of many subspecies of the then emerald toucanet (Aulacorhynchus prasinus sensu lato). In 2008 the International Ornithological Committee (IOC) split 10 of those subspecies to create seven new species, one of which is the black-throated toucanet, and retained four of them as subspecies of their current emerald toucanet sensu stricto. BirdLife International's Handbook of the Birds of the World (HBW) concurred. However, the North and South American Classification Committees of the American Ornithological Society and the Clements taxonomy declined to follow them. In 2017 they did split the emerald toucanet into two species, the northern (A. prasinus) and southern (A. albivitta) emerald-toucanets, each with seven subspecies. They treat the IOC's "black-throated" as three subspecies of the southern emerald-toucanet.[3][4][2][5][6][7][8]
Three subspecies of black-throated toucanet are recognized by the IOC and HBW:[2][5]
Like other toucans, the black-throated toucanet is brightly marked and has a large bill. Adults are 33 to 38 cm (13 to 15 in) long and weigh about 120 to 210 g (4.2 to 7.4 oz). The sexes are alike in appearance although the female generally is smaller and shorter-billed. The bills of A. a. dimidiatus and A. a. atrogularis are black a wide yellow stripe along the culmen; that of A. a. cyanolaemus is black with the only yellow on the tip of the maxilla. The bills of all three have a white vertical strip at the base. All three subspecies have plumage that is mainly green like that of other members of genus Aulacorhynchus, and is somewhat lighter below than above. Subpecies A. a. dimidiatus and A. a. atrogularis have black throats and A. a. cyanolaemus a blue throat. All subspecies have olive green legs and feet with dusky yellow soles.[9]
The three subspecies of white-throated toucanet are found thus:[2][9]
The black-throated toucanet primarily inhabits the interior of humid montane forest but is also found in more open landscapes like the forest's edge, secondary forest, plantations, and clearings with scattered trees. In Amazonia it is also found in lowland evergreen forest.[9]
The black-throated toucanet is non-migratory.[9]
The black-throated toucanet is gregarious and frequently gathers in small groups.[9]
The black-throated toucanet forages by gleaning in the middle to upper levels of the forest, usually while perched. Its diet is eclectic and includes a wide variety of fruits, terrestrial invertebrates, and small vertebrate prey.[9]
Little is known about the black-throated toucanet's breeding biology. Its nesting season in Peru is from May to September. It nests in a tree cavity like others of its family.[9]
The black-throated toucanet's vocalization in Peru is described as "a long series of grinding grunts grra grra grra...or barking yaps yak yak yak yak yak." In flight its wings make a whirring sound.[9]
The IUCN has assessed the black-throated toucanet as being of Least Concern. It has a large range, but its population size is not known and is believed to be decreasing. No immediate threats have been identified.[1] It is "vulnerable to habitat destruction".[9]
The black-throated toucanet (Aulacorhynchus atrogularis) is a near-passerine bird in the toucan family Ramphastidae. It is found in Bolivia, Brazil, Ecuador, and Peru.

Aulacorhynchus atrogularis
Le Toucanet à gorge noire (Aulacorhynchus atrogularis) est une espèce d'oiseaux de la famille des Ramphastidae.
Cet oiseau vit dans l'ouest de l'Amazonie.
Il a longtemps été considéré comme une sous-espèce du Toucanet émeraude (Aulacorhynchus prasinus) et pour cela, n'apparaît pas dans les listes de l'UICN.

O Tucaninho de nariz amarelo (nome científico: Aulacorhynchus atrogularis) é uma espécie de ave amazônica da família Ramphastidae.
Como outros tucanos, o tucaninho-de-nariz-amarelo é notavelmente brilhante e tem um bico grande. O adulto mede 30 a 35 cm de comprimento e o peso pode variar de 118 a 230 gramas.[1] Os sexos são parecidos na aparência, embora a fêmea seja geralmente menor e ligeiramente mais baixa. É, como outros membros do gênero Aulacorhynchus, principalmente verde. Narina e ponta da cauda são avermelhados. O bico é preto e a mandíbula superior é amarela; com uma faixa branca na base do bico. A garganta é azul ou preta e o anel ocular é muito escuro, quase parecendo preto à distância. As pernas são acinzentadas e a íris é escura.
São reconhecidas duas subespécies:[2]

Svartstrupig tukanett[2] (Aulacorhynchus atrogularis) är en fågel i familjen tukaner inom ordningen hackspettartade fåglar.[3]
Svartstrupig tukanett delas upp i tre underarter:[3]
Artgränserna inom arten och till dess närmaste släktingar är omdiskuterade. Underarten cyanolaemus urskiljs av Birdlife International som en egen art, "svartnäbbad tukanett". Andra inkluderar svartstrupig tukanett (inklusive cyanolaemus) i vitstrupig tukanett (Aulacorhynchus albivitta)[4] alternativt smaragdtukanett (A. prasinus) när den förra inkluderas i den senare.[5]
IUCN kategoriserar arten som livskraftig.[1]
