340 Wright, Nesting of the Blue-Winged Warbler. [oct* 



company with Mr. and Mrs. Edmund E. Bridge. They found the 

 male bird feeding and in song in a pasture perhaps fifty feet from 

 the highway. He seemed to be dividing his time between the apple 

 and the elm trees. Mr. Caduc states that all three had an ex- 

 cellent view of the warbler before he flew away and that the others 

 then continued their walk, while he set himself to the task of 

 locating the nest. His statement is: "I remained to await de- 

 velopments. I found a seat on a stone, well screened by a barberry 

 bush, and waited for a half-hour, when the male bird returned to the 

 same locality as before. For three-quarters of an hour he con- 

 tinued feeding and uttering the same song as when first seen. He 

 then changed to a call-note not unlike that of a Chipping Sparrow. 

 Very soon I detected an answer being made and the female bird was 

 seen for the first time [that day]. She flew to a pool in a swampy 

 section of the same pasture and bathed freely. Then alighting 

 on the same tree with her mate she was completing her toilet, when 

 to my surprise she flew to a black ant hill and took a dust bath 

 much after the manner of the House Sparrow. This done, she 

 again returned to the pool and drank freely, but I could not see 

 that she bathed again. Up to this time I do not think that she had 

 eaten anything, but she now began searching for food, and in a 

 more hurried manner than her mate. Passing from tree to tree 

 both birds soon showed me my real work had now begun. I had 

 no difficulty in following them, however, often being within three 

 or four feet of them, as they moved on feeding from one tree to 

 another. They did not seem to fear me. Neither bird gave voice 

 to any note whatever as over the pasture they led me and then about 

 two hundred feet into a wood. This wood was composed of chest- 

 nuts, oaks, maples, birches, and white pines, mostly of second 

 growth, with considerable underbrush including tangles of horse- 

 briar and wild grape, and with a brook flowing near by. Here the 

 female bird took to the ground and finally was lost to view behind a 

 decayed stump about a foot high and a growth of fern. A wagon- 

 road had been cut through the wood, and this I had been able to 

 follow up to this point. But in order to follow her course through 

 the underbrush I was obliged to assume a crouching attitude, and 

 it became necessary to approach on all-fours, as her point of dis- 

 appearance was about fifteen feet from the road. In this manner
