34 THE WILSON BULLETIN— March, 1921 



Ordinarily it appears here in numbers by February 15 to 22, the 

 earliest record I have being February 8. In the spring of 1920 

 the grackles were plentiful by February 26, when the coldest 

 weather of the season came, lasting until March 8. I am strongly 

 inclined to believe that they remigrated, for in that time only two 

 or three were seen, and they did not again become common until 

 March 12. 



I have never noticed this .condition about the birds which come 

 in late March or the early days of April. Regardless of Easter 

 storms, late snow flurries, or long-continued cloudy, cold weather, 

 the Chimney Swift and Purple Martin stay, even though I fear 

 they often approach starvation.

Freakish Nesting Habits. — ^Of the 45 or 50 birds which are 

 regular summer residents here four or five have odd habits choos- 

 ing sites for nesting. While the migration is on I have found a 

 few Prairie Warblers in several localities in the territory I have 

 studied, a circle about eight or nine miles in diameter, with 

 Bowling Green as its center. In nesting time, however, I have 

 never been able to see the Prairie Warbler outside of a little 

 side valley opening into the valley of the Big Barren River and 

 about three miles from town. Many other places around here 

 have the same general characteristics: shrubby fields, brier and 

 honeysuckle tangles, with wooded hills in the background, but 

 no other place seems to please the Prairie Warbler. 



The Bachman Sparrow is a little less choice about its nesting 

 grounds, but I have been unable to find it in the nesting season 

 except in three places, two of them fairly near each other, but 

 more than three miles from the other one. 



The range of hills overlooking the valley where the Prairie 

 Warbler nests is the only breeding ground I know of the Kentucky 

 Warbler, though there are dozens of hills near here very similar 

 to this range. 



Another bird which belongs to this group is the Oven-bird, 

 which is confined to the range of hills mentioned above, and an- 

 other, three or four miles from the first and across the river 

 from it. 



This season I intend to investigate this as one of my prob- 

 lems and hope to arrive at some conclusions concerning this unique 

 habit among these species.

Notes from Lake County. — I am pleased to record an occur- 

 rence of the Double-crested Cormorant on October 9, 1920. As I
