anywhere near a human habitation; and it is prob- 
ably owing to its recluse habits that its excellent song 
has not been hitherto noticed. Azara perhaps mistook 
the song of this species for that of Turdus rufiventris, 
a very inferior vocalist. 
The nest is made in the centre of a thick bush or 
tree six or eight feet above the ground, and is a deep 
elaborate structure, plastered inside with mud, and 
lined with soft dry grass. The eggs are four in 
number, oblong; the ground-colour light blue, 
abundantly marked with reddish-brown spots. 
This Thrush has, I believe, a partial migration in 
Buenos Ayres. In the autumn and winter I have 
frequently observed it in localities where it is never 
seen in summer.

Turdus rufiventris. 
Above olive-grey, throat to breast white, striped with dark brown ; 
under surface and under wing-coverts rufous red, deepest on the belly ; 
bill dull yellow ; feet brown; length 9 inches. 
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 district, and does not appear 
to be migratory. It is a noisy, strong-winged, quarrel- 
some bird, closely resembling the Dusky Thrush in 
its manners. It inhabits forests, runs on the ground
