last point we arrived early in April, returning thence directly to 
Azul and Buenos Aires. 
During this trip about 800 miles of the pampas were hastily 
crossed and the largest part of the time passed among the desolate 
sierras and the hardly more fertile plains at their feet. Collec- 
tions were made at all favorable points, but, the season being late 
summer and autumn, the birds taken were largely migrants and 
nearly all well-known species. Whatever of interest with regard 
to them was collected has been incorporated in the notes which 
follow. 
1. Turdus leucomelas Vieill. Zorzal (Thrush) of the 
Entre-Rianos. — This bird abounds at Concepcion the year round, 
and was taken also at Buenos Aires. It was not observed either 
at Azul or any of the points further south. It is found in the 
gardens of the town as well as in the depths of the swampy 
woods, but never seen far from leafy cover of some kind, and 
does not appear at home on the ground. It is very unsuspicious 
and is frequently caged and becomes reconciled to its imprison- 
ment, yet is not very musical. The nest is usually well hidden 
among the tops of bushes or masses of twining plants, never 
more than ten feet from the ground, and resembles in general the 
nest of our own Robin, but is smaller and contains no mud in 
its composition, so far as my observation goes. The eggs, 
commonly four, are splashed and dotted with several shades of 
brown on a dirty green ground. Sets were taken through Octo- 
ber and November, and frequently the eggs of the Cowbird were 
found with them. 
2. Turdus rufiventris Vieill . Zorzal vientre Colorado 
(Red-bellted Thrush). — Less abundant and more retiring 
than the preceding ; seldom seen except in the woods. Resident 
through the year at Concepcion. In breeding habits precisely 
similar to the preceding, and the nest and eggs of the two species 
are generally indistinguishable, though the eggs of the present 
species would probably average a little larger. 
3. Mimus calandria ( Lafr . & d’Orb.). Calandria. — 
Very abundant and well known, and resident at Concepcion 
through the year. Undoubtedly a fine singer, but its song, so far 
as my observation goes, is far inferior to that of our own Brown 
Thrush ( Harforhynchus rufus ), and cannot approach at all that 
of our Mocking Bird. 1 have never heard it sing for more than
