Birds of Uruguay. 179 



46. CyANOTis AZARiE. Many-coloui'ed Tyrant. 



This M'onderfully-coloured little bird, known in Argentina, 

 as " Siete colores/^ is only an autumn visitor and rare. I 

 only met with it twice. On the 9tli March I found one 

 flitting about the rushes and water-plants at the edge of the 

 Sta. Ana Saiice, and after a long time succeeded in shooting 

 it, only to lose it in the thick herbage. The other, a male, 

 I shot in a precisely similar locality on the Sta. Elena 

 Sauce ; in both cases the ground on the banks was inclined 

 to be boggy. 



47. Elainea albiceps. White-crested Tyrant. 



I met with this Tyrant only twice, in November and March, 

 at Sta. Elena. I have seen it in the monte hawking at flies 

 from a bush. 



48. Pitangus bolivianus. Bien te veo Tyrant. 

 Common and resident. Breeds early, for a pair the nest and 



young of which had been blown out of an ombu in the outer 

 patio in a pampero were busy building again in a gum by the 

 25 th October. A nest on the 22nd November in the small 

 branches of a cina-cifia was very big, long, and heavy, of an 

 oblong shape, with a hole near the top of one side ; it was 

 built of sticks, roots, and a great deal of wool, lined with 

 feathers of Tinamu, &c., and contained five eggs. From the 

 amount of wool these birds use now, you M^onder what they 

 made their nests of before sheep were brought into the 

 country. The Venteveo generally makes its nest in the small 

 twigs on the outside of a tree or bush, and although, from 

 its position, this bulky afi^air frequently sufiers from high 

 winds, yet when placed in a thorny tree it is generally quite 

 safe from would-be human robbers. It is unnecessary to 

 enter fully upon the habits of this well-known bird, but I 

 may call attention to its good offices in eating the larva of 

 the isoca beetle, so injurious to grassroots ; when searching 

 for them I have seen it hovering over the ground like a 

 Kestrel. 



49. Myiobius NiEvius. Little Brown Tyrant. 



Fairly common in the monte, where it sits on low bushes.
