AND OOLOGIST. 



lar part of the world entirely and gone to 

 some place where egg collectors are as 

 scarce as Red-tailed Hawks are in others. 

 By April 3d, their work on the nest was 

 done and after a very laborious climb 

 April 7th, I was rewarded with a fine set 

 of three eggs, pure white. I then visited 

 a Cooper s Hawk's nest and returned half 

 an hour later and found the female sitting 

 on the empty nest. They visited the nest 

 daily for several weeks and sometimes the 

 female would sit for several hours upon it, 

 but I am certain they did not lay again ; 

 for I climbed to it April 28th and found 

 it empty. They have not built a second 

 nest, but have remained very close to the 

 old one up to this time (June 4th). At 

 any hour of the day you can find both 

 birds very close to the tree containing 

 the nest. Will they use this nest again 

 next spring ? Time will tell. Another 

 question : Why do they stay so close 

 to their nest all this time without lay- 

 ing when the other pair were so per- 

 sistent as to construct three different 

 nests '? On April 12th, I found two more 

 nests, both of which were occupied by 

 birds, and also another on April 19th, all 

 of which were in places not to be reached 

 without endangering life or limb. My 

 time was very limited at this season of the 

 year for collecting, or I doubtless could 

 have taken more. May 26th, a friend who 

 has been trying to raise them by hatching 

 the eggs under a hen, sawed off a horizon- 

 tal limb of an oak, forty-five feet from the 

 ground, on which was placed a nest con- 

 taining three young, about half grown. 

 The young were all killed by the fall. 

 Nests containing two young or two eggs 

 are very rare in this locality. Three is the 

 usual number, and in one instance I found 

 four. A few years ago there was a poultry 

 show here, and among other things on ex- 

 hibition was a beautiful pah* of these 

 birds. A gentleman had brought them in 

 from the country. On questioning him as 

 to the mode of capture, he informed me 



that he had taken them both in steel 

 traps, by placing the trap on the ground 

 in a meadow and partially covering it with 

 grass and placing a piece of rabbit fur on 

 top. He said on seeing it they would make 

 a swoop and get caught. They appear very 

 contented while in captivity and, if young, 

 will soon take food from the hand. A gen- 

 tleman near here has one in the same cage 

 with a Bald Eagle and they are very con- 

 tented. I am going to capture one this 

 fall and put it in the cage with my Great- 

 horned Owl to see how they will get along 

 together. October and November are the 

 best months to collect cabinet specimens, 

 as the birds are then in then- best plum- 

 age. — Horace A. Kline, Polo, III. 



Black-throated Green Warbler. 



June 14th, I found a nest of this species 

 containing three young, less than a week 

 old. The nest was ten feet from the 

 ground, saddled upon a maple limb and 

 held in place by several twigs, the leaves of 

 which made a complete covering over it. 

 Fine strips of. birch bark, cobwebs, dry 

 hemlock twigs, hairs, and fibrous barks, 

 closely interwoven, formed the exterior, 

 fine dry grass and fibrous barks, with an 

 abundant lining of hah', the interior ; the 

 whole forming a neat and compact piece of 

 bird architecture. Measurements, outside 

 diameter, 3. X 2.75 inches ; height 2 inches ; 

 inside diameter 1.75x1.50 inches; depth 

 1.55 inches. 



When first disturbed the female bird, 

 fluttered from the nest, alighting on the 

 ground almost at my feet, and remained so 

 for several minutes, showing no signs of 

 fear, but giving me an excellent oppor- 

 tunity of observing her. 



Upon a subsequent visit, however, she 

 was very shy and wary, retiring to the 

 thick foliage, where she frequently uttered 

 a "chip" not unlike that of the chipping 

 sparrow. This Warbler occurs here com- 

 monly as a migrant, and rarely during the 

 breeding season. — O. 0. T., Taftsville, Vt.
