PACIFIC AUDUBON'S WARBLER 271 



"In the evening, foraging over the ground as they went, the Audubon 

 warblers and bhiebirds would go together to bathe in one of the 

 rivulets that flowed through the pastures. After splashing vigor- 

 ously in the shallow water they would fly up together into the raijon 

 bushes, shake the drops from their feathers, sometimes wipe their wet 

 faces against the branches, and put their plmnage in order again. The 

 last Audubon warbler that I saw in the spring was a lone female, who 

 foraged in company with a pair of the resident bluebirds in the open 

 pasture. She must have appreciated the companionship of the blue- 

 birds more than ever, after all of her own kind had departed for more 

 northerly regions. 



"Guatemalan dates are : Sierra de Tecpan, January 16 to April 23, 

 1933; Sierra Cuchumatanes, September 13, 1934; Chichicastenango 

 (Griscom), November 16."
