296 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB. 



ber 4th, 1903, I watched one within ten paces, and could clearly distinguish the 

 yellow lower tail-coverts and dirty white breast and abdomen as well as the 

 chestnut crown. 



283 [672a] Dendroica palmarum hypochrysea Ridgw. 

 Yellow Palm Warbler ; Yellow Red-poll. 



Abundant transient visitor; April 13 to May 6 (May 21); October 14 to 

 October 26; average date of arrival in the spring for eight years, April 19. 



The unusually late date, May 21st, was in 1904, when Mr. Horace W. 

 Wright sav/ one of these birds at Ipswich. The Yellow Palm Warbler is some- 

 what irregular in the autumn migrations, at times abundant, at times hardly 

 showing itself. On October 14th, 1900, in a violent northeast storm with rain, 

 I found the Ipswich dunes swarming with these birds. On April 19th, 1904, I 

 found one at Thatcher's Island that had killed itself during the night by striking 

 one of the lights.

In the dry pastures of Swampscott with their growth of barberry bushes 

 and junipers, the Prairie Warbler is found as a summer resident. I have found 

 it in September among the dunes at Ipswich.
