BIRDS OF NEW YORK 429 



with the male who had been singing over and over his whirlwind trill in 

 a distant part of the wood. However, he refused to take any part in 

 protesting with the female against my presence, but persisted in his rolling, 

 whistling trills in the near-by trees while the female came toward me 

 slowly moving about among the branches uttering a mild ' peet, peel.' 

 The nest contained 4 fresh eggs. It was firmly attached to the limb and 

 almost hidden from below by clusters of cones. It is composed of strands 

 of grapevine bark, fine rootlets and horse hairs, decorated with bits of brown 

 and white spider cells and lined with a compact mass of animal hair and 

 fluffy feathers with a thick ring of woolly material around the rim. The 

 other nest found on June 6th contained 3 eggs and I of the Cowbird; as 

 usual, i egg,of the warbler was punctured. This nest was placed about 

 50 feet from the ground in a Norway pine and 4 feet out on a crooked, 

 cone-laden limb, over a cleared place along the edge of the wood. This 

 nest is made outside of hemlock twigs, strands of grayish weed bark, grape- 

 vine bark and fine reddish rootlets, lined with animal hair and crow feathers. 

 Both of these nesting sites were somewhat isolated from other coniferous 

 trees in portions of the wood surrounded by deciduous trees. The Pine 

 warbler does not seem at all shy. I watched the female feed the young 

 ones only 5 feet away while I sat on a limb 40 feet above the ground. 

 Another time I hastily dismounted from my bicycle to observe a bird 

 gathering horse hairs from the roadside only 8 feet away and apparently 

 unconcerned about my presence. Another time while I was sitting quietly 

 at the base of a pine, a female warbler hopped about on the ground so 

 close that I could have touched her with my hand."
