1882.] FROM THE ARGENTINE REPUBLIC. 623 



160. Geranospiza c^rulescens (Vieill.). 



c?. Campo Colorado, Oran, Salta, Arg. Rep., Nov. 4, 1880. 

 Iris yellow. 



1 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. 



161. TiNNUNCULUs sPARVERius (Linn.). 



d". Fuerte de Andalgala, Catamarca, Arg. Rep., Sept. 9, 1880. 



2 . Pilciao, Andalgala, Catamarca, Arg. Rep., Sept. 16, 1880. 

 Iris brown. 



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 T. cinnamominus for those who accept this subspecies. 

 Cf. Gurney, Ibis, 1881, p. 654.— P. L. S.] 



162. Elanus lexjcurus (Vieill.). 



c? ?. 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. Spiziapteryx circumcinctus (Kaup). 



$ . Guazan, Andalgala, Catamarca, Arg. Rep., Sept. 5, 1880. 

 Iris amber. 

 A rare bird in this neighbourhood, as this was the only specimen 



seen. 



164. Milvago chimango (Vieill.). 



(S . Salto, Buenos Aires, Arg. Rep., Oct. 14, 18S1. 



$ . 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.
