60 Mr. H. Durnford on the Birds of 



11. Alectrurus guira-yetapa (Vieill.) ; Nomencl. p. 43. 

 The only occasion on which 1 have seen this bird was on 



the 11th February 1877, when I met with two near Lujan 

 bridge. I found them in a dry open space, where the " paja " 

 grass had been recently burnt during the dry weather. They 

 clung to the tall stems o£ the grass which was still standing, 

 or flitted rapidly from one to the other, catching insects on 

 the wing. They were both immature birds. Iris dark wood- 

 brown; legs and feet black; beak yellowish horn-colour, 

 under mandible lightest. Their stomachs contained remains 

 of small Coleoptera. 



12. LicHENOPS PERSPiciLLATUs (Gm.) ; Ibis, 1877, p. 176. 

 This bird nests in October. Its nest is made of small 



pieces of rushes or grass, lined with hair, and placed in a tuft 

 of grass about two feet from the ground, and in the imme- 

 diate neighbourhood of water. Their first moult takes place 

 in February, and then the males put on their decided colours, 

 whilst the females remain almost the same as before : pre- 

 vious to the moult both sexes are alike. 



13. Hapalocercus flavtventris (Lafr. et D'Orb.) ; Ibis^ 

 1877, p. 177. 



This bird nests about eighteen inches from the ground, in 

 a clump of grass or low bush, and makes a very neat struc- 

 ture of fine grass, warmly lined with feathers and wool. I 

 have not found the eggs. 



14. Elainea albiceps (Lafr. et D'Orb.) ; Nomencl. p. 48. 

 This is a spring and summer visitor, and at these seasons 



pretty common, especially in the riverain wood. The nest- is 

 a small and very neat structure of lichen or moss, lined with 

 hair and feathers, not unlike our English Chaffinch's nest, 

 and is usually placed about ten feet from the ground in the 

 fork of a tree. 



15. Myiodynastes solitarius (Vieill.) ; Ibis, 1877, p. 178. 

 Iris wood-brown ; beak, legs, and feet black, soles of latter 



flesh-colour.
