CHERRIE: ORNITHOLOGY OF THE ORINOCO REGION. 233 



(No. 10,768, 10,769 Coll. G. K. & Stella M. Cherrie) were apparently 

 year-old, abandoned nests of the common yellow Oriole (Icterus 

 xanthornus}. A few small dead leaves of the Salada tree formed 

 a lining, but whether they had been carried in by the birds or had 

 fallen there by chance seemed open to question. The first of these 

 nests contained a single egg, the second contained two eggs. In each 

 case the parent birds were collected, the female taken with nest No. 

 10.768 Cherrie Coll. having an egg in the oviduct. A nest without 

 eggs, together with the owners, taken at Caicara, May 4, 1905, is 

 exactly similar in materials employed and style of structure with an- 

 other nest of Icterus xanthornus, containing eggs, that hung within a 

 few feet of it in the same tree. Also in the same tree were nests con- 

 taining eggs of Pitangus derbianus rufipennis and Myiosetetes super- 

 ciliosns columbianus. 



An egg collected with the nest (one originally built by the yellow 

 Oriole), and female parent bird at Auga Salada de Cuidad Bolivar 

 April 17, 1907, is ovate in form and measures 22 x 15 mm. The ovi- 

 duct of the female contained two imperfect eggs indicating that the 

 full set would have been three. On the 7th of May, at Caicara a nest 

 containing one egg just on the point of hatching and a day old chick, 

 was collected ; the full set in this case was evidently two.
