Tris yellow. 
I shot this pretty Falcon whilst perched motionless on alow branch 
of a tree in the dense forest. 
It was the only one of the species I had hitherto seen; but sub- 
sequently I met with one on the Upper Uruguay.

I have met with this Sparrow-hawk in many parts of the Republic. 
Its flight is limited from clump to clump of trees, perching usually 
on bare or dead branches. 
[Probably 7. cinnamominus for those who accept this subspecies. 
Cf. Gurney, Ibis, 1881, p. 554.—P. L. S.] 
162. ELanus Leucurus (Vieill.). 
3 2. Monte Grande, Buenos Aires, Arg. Rep., Dec. 31, 1880. 
Iris yellow. 
This White Hawk was shot as it was flying about close to the 
Estancia house of Monte Grande; but I have not noticed it 
in any other parts of this province, although subsequently two or 
three other pairs have been observed about the same locality, It 
was nesting in some lofty trees. 
The eggs are very similar to those of Milvago chimango. 
163. SpiziapreRYx CIRCUMCINCTUs (Kaup). 
2. Guazan, Andalgala, Catamarea, Arg. Rep., Sept. 5, 1880. 
Iris amber. 
A rare bird in this neighbourhood, as this was the only specimen 
seen. 
164. Mitvaco cu1manco (Vieill.). 
3. Salto, Buenos Aires, Arg. Rep., Oct. 14, 1881. 
. Punta Lara, Buenos Aires, Arg. Rep., Feb. 19, 1881, 
Iris brown. 
In the forks of trees, frequently of the Eucalyptus, this bird builds 
its open nest of twigs, lined with grass ; but the structure is by no 
means large for the size of the bird. The Chimango is very de- 
structive to house-pigeons on an Estancia. The breeding-season 
commences early in October. The eggs, of which there are three 
in a clutch, are rounded and of a rufous-brown ground sprinkled 
with flakes and spots of the same, but much darker, tint. 
Meas. : axis 42 mill., diam. 34 mill. 
Legs and feet of a dirty yellow, and base of beak the same.
