Dark-throated Thrush (other)
Dark-throated thrush can refer to one of two bird species, formerly regarded as conspecific: *Black-throated thrush ''Turdus atrogularis'' *Red-throated thrush The red-throated thrush (''Turdus ruficollis'') is a passerine bird in the thrush family. It is sometimes regarded as one subspecies of a polytypic species, "dark-throated thrush", black-throated thrush then being the other subspecies. More r ...

Conspecific
Biological specificity is the tendency of a characteristic such as a behavior or a biochemical variation to occur in a particular species. Biochemist Linus Pauling stated that "Biological specificity is the set of characteristics of living organisms or constituents of living organisms of being special or doing something special. Each animal or plant species is special. It differs in some way from all other species...biological specificity is the major problem about understanding life." Biological specificity within ''Homo sapiens'' ''Homo sapiens'' has many characteristics that show the biological specificity in the form of behavior and morphological traits. Morphologically, humans have an enlarged cranial capacity and more gracile features in comparison to other hominins. The reduction of dentition is a feature that allows for the advantage of adaptability in diet and survival. As a species, humans are culture dependent and much of human survival relies on the culture and so ...

Black-throated Thrush
The black-throated thrush (''Turdus atrogularis'') is a passerine bird in the thrush family. It is sometimes regarded as one subspecies of a polytypic species, "dark-throated thrush", red-throated thrush then being the other subspecies. More recent treatments regard the two as separate species. The black-throated thrush is a migratory Eastern Palearctic species. Its range overlaps with the more easterly-breeding red-throated thrush. Description This is a large and distinctive thrush. The male has black from the chin to the breast with a greyish black tail. The upperparts are grey and the underparts are whitish with orange-red underwing coverts. Females and immatures are similar but the black on the throat and breast is replaced with dusky streaking. Habitat Black-throated thrushes breed along the edges of clearings in coniferous or mixed deciduous forest, often in the undergrowth of Siberian Pine '' Pinus sibirica'' or mixed spruce fir forest, especially along watercourses o ...
