_Description._--Entire upper parts olive-grey; throat white, striped

with dark brown, the striped portion extending to the chest; rest of

under surface, also under wing-coverts, rufous-red, deepest on the

belly; bill brownish yellow; feet brown: total length 9·0 inches,

_Hab._ S.E. Brazil, Paraguay, Uruguay, and La Plata.

The Red-bellied Thrush, distinguished from the species just described

by its larger size and the bright rufous colour of its under plumage,

is common everywhere in the Plata region, and does not appear to be

migratory. It is a noisy, strong-winged, quarrelsome bird, closely

resembling the Dusky Thrush in its manners. It inhabits forests, runs

on the ground in search of food, and when approached darts away with

loud chuckling notes, flying close to the ground. These birds are also

often seen pursuing each other through the trees with loud harsh

screams.

The song has a faint resemblance to that of the English Song-Thrush,

being composed of a variety of notes uttered in the same disconnected

manner, with frequent pauses; but it is, both in sweetness and strength,

inferior to that of the English bird. As a rule this Thrush sings

concealed in a thick bush or tree.

The nest is deep, well made, plastered inside with mud, and concealed in

the centre of a large bush or low tree. The eggs are four, pale blue in

colour, and thickly spotted with brown.
