is a short chirrup. It is constantly occupied in the pursuit of insects, and is frequently 

 seen in company with Hirundo riificoUis. I found the nest in an old tree-trunk, 

 split by the water, and fast buried in the sand : it was placed at the end of the tree 

 between the wood and the bark, and consisted of an exposed mass of dry grass and 

 stalks mixed with feathers, amongst which were some of the red plumes of the Macaw 

 {Ara macao) and the green feathers of a Surukua {Trogon). The depth of the nest is 

 very small, and two white eggs were found in the beginning of October or the end of 

 September." 



Mr. E. Bartlett found the species breeding in the Ucayali River. He writes : — 

 " Builds in holes of dead trees on the banks of rivers overhanging the water. The 

 nest is composed of fibres of bark, dry grass, and feathers of different kinds of birds, such 

 as the White Heron, Roseate Spoonbill, &c. Eour white eggs are laid in July or 

 August." The eggs are said to be of about the same size as those of the Common 

 Martin of Europe. 



The descriptions are taken from birds in the British Museum, and the figures in the 

 Plate, which represent an old and a young bird, the former from a specimen in the 

 Salvin-Godman collection, and the latter from a bird procured by Mr. Wyatt in the 

 Magdalena Valley.
