34 PROCEEDINGS OF THE 



township, Bucks Co., Pa., early part of June, '97, '98, '99, 1 

 met with quite a number of nests, mostly built in dogwood, 

 viburnum and chestnut, in the second growth of thickets, 

 placed about eight feet above the ground. From two to four 

 eggs are laid. The male is as often found on the nest as the 

 female during incubation, and I have located a number of nests 

 through this fact by the male singing while covering the eggs. 

 The male sings quite a good deal about the nesting grounds, 

 and can be heard from some distance on approaching them. 

 They are hard to flush from the nest, especially when the eggs 

 are heavily incubated. The nest is remarkably well built for a 

 bird with so heavy a bill, and the walls are so thin that the 

 eggs can be readily counted through it from below. They 

 select a thicket verj' densely grown up, and the nest is often 

 woven about the branches of several bushes interlacing one an- 

 other, and requires great care in separating the bushes to get at 

 it. One of these nests I donated to the Wagner Institute, 

 17th and Montgomery Ave., Phila., one to Mr. Voelker and one 

 to Mr. Moon. The latter was with me on one of these trips, as 

 well as Dr. W. E. Hughes." =i= * *
