XIPHOLENA. — lODOPLEURA. 303 



The female described was collected at Bartica in 1911. 



The young male is similar to the adult female in its first 

 plumage. The first appearance of the male dress I notice in one 

 example is the approach of purple on the scapulars and middle of 

 the abdomen, while in another specimen which has nearly attained 

 the full plumage of the adult male it still retains, for the most 

 part, the blackish-brown flight-quills of the female. 



The young bird referred to was collected at the Great Falls 

 Demerara River in August 1913.

Habits. According to Schomburgk (Reis. Guian. ii. p. 90) this 

 bird is not found in the woods during the months from March to 

 October, but is common in November, December, and to about the 

 middle of January. He did not know the time of its nidification. 



Schomburgk also writes (op. r«^. iii.p. 693): — This gorgeous bird 

 is also of sporadic occurrence in British Guiana. Near Demerara 

 it is found during the months of December, January, and Feb- 

 ruary, and near the Upper Takutu River in April. Its favourite 

 food is the red fruits of the small Ficus, also the Brosimum species. 

 I have never seen quite young birds, but only those in the transit 

 plumage of an approximate age of two to three years. The 

 " Arawaaks " call it Wallaha.
