Thrombosis
in pathology, local formation of clot, called a thrombus, 1 THRUSH has several European species, but to only three of these is the name thrush applied. The song thrush, throstle, or mavis (Turdus musicus), the missel thrush (T. viscivorus), and white thrush (T. vawhite thrush (T. vαrius). The song thrush, common, is not quite nine inches long; back and upper surface brown of slightly different shades, chin white, abdomen and tail coverts grayish-white; throat, breast, and flanks, together with the sides of the neck, yellow, thickly spotted with dark-brown. It is one of the bestknown European song birds, and in captivity is easily taught simple airs. It is found all over Europe, but leaves some of the N. parts in winter, being thus practically a bird of passage.
It feeds on insects, worms, slugs, snails, and in the summer greedily devours cherries and smaller fruit. It usually builds a cup-shaped nest in a thick bush or shrub, and lines the interior with mud, clay, or dung. The eggs are four to six in number, bright bluish-green, with brownish spots. They usually produce two broods in the season.
