Todd-Carriker : Birds of Santa Marta Region, Colombia. 525 



on June 8; another in a similar stage is dated July 7, while a third shot 

 June 11 is entering upon the postjuvenal moult. Several of the pre- 

 sumably adult birds show more or less dusky mottling on the breast, 

 and there is also a tendency towards a dusky suffusion on the back. 



One of the species peculiar to this region, having been described 

 by Salvin and Godman from a young bird secured by Simons at San 

 Sebastian. This collector subsequently took an adult at San Jose, and 

 the species continued to be known only from these two specimens up 

 to the time Mr. Brown visited the Sierra Nevada, when a good series 

 was secured, including examples from the type-locality. Mr. Smith's 

 collectors found it also in the San Lorenzo range, and it appears to be 

 a common bird in both districts. It is a Subtropical Zone form, not 

 found below 4,000 feet in the San Lorenzo district, but coming down 

 as low as 2,000 feet on the north slopes of the Sierra Nevada, at Pueblo 

 Viejo. It runs as high up as 8,000 feet in the San Lorenzo, and to 

 about the same altitude in the Sierra Nevada, although above 6,000 

 feet it is not so common there, the temperature being much lower than 

 at corresponding altitudes on the former mountain. It occurs under 

 almost all kinds of conditions throughout its range — in the forest, in 

 scrub-growth, and even in low bushes in the open. It is invariably 

 found in pairs, keeping near the ground, and is not at all shy. The 

 nest is made of grass and rootlets, domed over, and placed in a low 

 bush or shrub. The eggs are two in number, and pure white.

There is considerable variation, apparently of an individual nature, 

 in the brightness of the olive yellow of the back and wing-coverts. 

 No. 38.C90, August 16, is apparently just completing the postjuvenal
