Description

The Black-throated Thrush in size and proportion is mostly similar on the Fieldfare; slightly less. The adult male has the large black patch on the throat and breast; brownish-grey back; dark-brownish tail; light-grey underparts; and the washed dark streaks on flanks. Spring male is unmistakable identified; though the black throat patch is very variable on size and color (from dark-brownish to velvet-black; sometimes with the whitish mottles, especially under the beak). The female has on the craw the concentration of the dark streaks formed more or less compact dark bib. The Black-throated Thrush is distinguished on Fieldfare by the almost plain color of upper parts and the absence of rufous tones on under parts. Autumn males are similar on females by the color of head and breast, but notably darker. Juveniles on first plumage are also similar on females but have the light streaks on back, the rufous tips of wing coverts, and the dark streaks on breast and flanks. Underwings are rufous in all plumages. Weight 70-110 grams, length 24-27, wing 12,5-14,2, wingspan 40-45 cm.
