Blackbird thrush bird is a strong-legged, sprightly, ground-feeding long-tailed bird. The Blackbird thrush bird (male) is all black, with an orange-yellow bill and eyering, the Blackbird thrush bird (female) is uniform dark brown with slightly paler central throat and faint mottling on the malar stripe and breast. Immature birds are brown like the females, with males in their first year showing a black tail and sooty plumage; fledged juveniles have rufous-tipped feathers.
Blackbird thrush bird is found in all types of forest and woodland with undergrowth, in farmland, scrub, copses, hedges, gardens and parks, as well as moorland and wetlands provided that cover and undergrowth are available; it also reuires open and bare ground for feeding. Common and resident in Britian, with populations supplemented in winter by northern and eastern birds migrating to western Europe from further east.
Blackbird thrush bird is very vocal, with a rich repertoire of calls. One of the loudest - and therefore most familiar - is the alarm call, a loud, often hysterical, tinking and clucking such as "chink chink chink chink..." or "plih! plih! plih!", when the neighbourhood birds start 'kicking off' at dusk prior to roosting, often accelerating the calls into a manic crescendo when taking flight. This is also used in mobbing situations. Variations include a less intense, low "chuck chuck chuck". Other calls are the 'ground predator alert' call, commonly used for cats, a soft "pock" or "puhc", and frequently heard when parents have fledged young and are keeping watch for danger. Blackbird thrush bird also has a thin, drawn-out and descending "sseeh", given in alarm, and a more rolling "srrri", typically used on migration. The song is rich, confidently languid and pleasing, with a series of fairly low-pitched fluty notes uttered in phrases lasting 2-4 seconds, usually tailing off into low chuckling notes and often with an equal length pause between. Each male has wide variety of song phrases, sung from a prominent perch such as a roof or treetop.
