ture birds. It is also fairly common, though local, during 

 the summer. A pair were seen mating on May 15 ('92), and 

 young birds out of the nest are noted from June 3 to July 18 

 ('93, Gray). On June 20, '93, Mr. W. H. Fisher and I found 

 them very numerous at Mount Washington. In a walk of about 

 three-fourths of a mile we noted 9 pairs feeding young, and no 

 doubt there were others we did not see. Sets are 3 of 3. At 

 Washington it is "a common migrant, first noted on April 19, 

 '91. A few breed. Hasbrouck found a nest with 4 eggs nearly 

 hatched on May 21, '88" (Richmond). On Dan's Mountain, 

 June 5 to 14, '95, they were very numerous; their numbers 

 about equalled that of all other birds seen there. On the 9th 

 young birds left a nest before I could count them.

 to May 4 ('89); more numerous in October, November and 

 March and April than in midwinter. They were common until 

 November 30, 90 " (Richmond). 



On November 12, '93, I found a large flock in Dulaney's 

 Valley ; some were running and presumably feeding on pas- 

 ture, others on a part that had been newly turned up, while the 

 greater number were either bathing in a shallow puddle or 

 dressing their feathers in an adjoining tree, being perched on 

 the branches from the ground up to the top, fully 50 feet from 

 the ground ; they, however, were more at home on the fence
