DescriptionHere are some facts about the Black Throated Thrush Turdus atrogularis.jpg |
English: The Black-throated Thrush, classified as a passerine bird within the thrush family, is often considered a subspecies of the polytypic species known as the "dark-throated thrush," alongside the red-throated thrush as the other subspecies. However, recent treatments increasingly recognize them as distinct species. This dark and somberly-colored thrush primarily inhabits middle to high-altitude forests and typically winters at higher elevations, occasionally venturing into foothill and lowland areas.
The male Black-throated Thrush is easily identifiable by its gray back, white belly, and a striking pitch-black throat and chest. In contrast, females exhibit streaky brown plumage below and may be confused with the Red-throated Thrush. Notably, Black-throated females lack the orange coloring on the throat and sides of the tail present in their counterparts. The only warm colors on either gender are the orangish underwings. In regions where the two species overlap, caution is advised, as hybrids may display features of both. The Black-throated Thrush's distinctive song comprises various repeated phrases, while its call includes a low "chekchekchek" and a high, thin "tseee." Key characteristics of this species, Turdus atrogularis, include its rarity as a visitor from eastern Asia and its slightly larger size compared to the Song Thrush. Males are characterized by a gray back, white belly, and a prominent pitch-black throat patch. Conversely, females, with streaky brown plumage below, may be mistaken for the Red-throated Thrush. Females and immature birds share similar features, but the black throat and breast are replaced with dusky streaking. Noteworthy features include an off-white lower breast, breast side, belly, and flanks with broad, indistinct streaking, as well as a dark bill with a yellowish lower mandible. The legs of the Black-throated Thrush are reddish-brown. Recorded sightings in Scotland predominantly occur in autumn, while in England, observations are evenly distributed between autumn and winter. |
