NOTES' ON GUA)TEM..\L.AN BIRDS — WETMOIRE 571 



23, and two were shot at 10,200 feet at Desconsiielo on November 24. 

 The birds ranged in deciduous growth and in the pines, often in 

 company with migrant warblers from the north. In the dense 

 growth they moved quickly so that it was difficult to keep them in 

 sight, particularly as they were prone to move behind cover, though 

 they were less active than many other warblers. Seen against the 

 light, they appear entirely dark, so that their lovely colors come as 

 a vivid surprise when one appears against the dark green foliage of 

 the trees. They were silent so far as my observation extended. 



This species is so distinct in head markings from Ergaticu^^ ruber 

 that I can see no basis for Hellmayr's action ^° in uniting these two 

 as geographic races. 



WILSONIA PUSILLA PILEOLATA (Pallas) : Northern Pileolated Warbler

 (Kodiak Island, Alaska). 



Through the highland portion of Guatemala this was one of the 

 most common and widely distributed of the migrant warblers during 

 my observations. One was seen on November 8, at 3.200 feet eleva- 

 tion below Alotenango, and from here they were encountered to 

 10,000 feet wherever there was suitable place for them. They ranged 

 from thickets near the ground to the tops of tall trees, moving actively 

 with constantly twitching tails and soft call notes. It is probably 

 these call notes that have brought the name of chip (to be pronounced 

 as in Spanish) to all of the small, yellow-breasted warblers found in 

 Guatemala. The five specimens taken, all pileolata^ were secured as 

 follows: 6,500 feet elevation Volcan de Acatenango, above Duehas, 

 October 29; 3,800 feet at the eastern base of Volcan de Fuego near 

 Alotenango, November 2; Panajachel, November 15; and Sierra 

 Santa Elena, November 20.

 I shot a male near the ground in rather dense growth. It moved
