Wafer Bay. While watching some small birds in the treetops, sup- 

 posed to be immature golden warblers, we noticed one with a broader 

 bill and promptly collected it. Later, while we were squeaking to 

 attract birds in low marsh land, a pair of these flycatchers appeared 

 and joined some golden warblers and finches which were earlier ar- 

 rivals. In action, as they passed from twig to branch, they were not 

 different from the golden warbler. These three were the only ones 

 seen, although considerable search was made for others. 



PYROCEPHALUS NANUS NANUS Gould 

 Galapagos vermiliou flycatcher 



PyroccphaJus nanus Gould, Zool. Voy. Beagle, pt. 3, Birds, July, 1839, p. 45, 

 pi. 7. (Several Islands of Galapagos Archipelago.) 



One male and three females were obtained on Indefatigable Island 

 June 18, 20, and 24, and a male and a female on Charles Island 

 June 27 and 28, 1929. The female from Charles Island is an im- 

 mature bird with breast of deep buff lightly streaked, differing so 

 decidedlj'^ from one of similar age from Indefatigable, which is pale 

 3^ellow below, as to indicate that further study of Pyrocephalus 

 carolensis Kidway ^* may show that that supposed form may be dis- 

 tinct, rather than a synonym of P. nanus as now considered. In 

 view of the evident close relationship of the two recognized forms of 

 Pyrocephalus from the Galapagos, it seems proper to consider them 

 as subspecies rather than as distinct species. 



This form of vermilion flycatcher was common on Indefatigable 

 and Charles Islands, and a male was seen on Barrington. The 

 females were very tame and on one occasion tried to alight on a 

 gun that was being carried on the shoulder. The males were shyer 

 and consequently less often seen. Persecution ma}^ account for this, 

 since they are the only bright-colored birds on the island. The 

 breeding season probably was over, for the males were silent, and 

 were not seen to go through the wonderful aerial gyrations that form 

 a regular mating manifestation in the Arizona form.
