Yellow-throated Vireo. — The nest was found on May 31, 1893, by 

 looking in the tree where I had found nests in 1891 and 1892. This nest 

 was not two feet from the 1892 site. It was about twenty feet up in a 

 large sugar maple by the road side, and overhanging a barnyard. Some 

 cedar bean poles in a garden across the way had supplied bark for the 

 body of the nest, and the "ornaments" were, as always, green moss and 

 plenty of white spider's egg cases, picked from tree trunks and the near- 

 est fences. The nest contained at the time three eggs, and the birds 

 objected strongly to my handling them. On June 5, the bird was sitting, 

 and again on the loth and nth. They are very reluctant to leave the nest 

 more and more so, I think, as time passes. I have twice touched a female 

 with my fingers before she would leave a nest of freshly hatched young ; 

 this in the pleasantest of June weather too ! On June 17, the young were 

 out — four or five days old, having pin-feathers on the back 1-16 inch long. 

 Supposing them to have been four days old, this makes the period of in- 

 cubation twelve days. Such " estimates " as this are always unsatisfac- 

 tory, but may serve to emphasize the need of more industrious field work 

 in such matters. Henry R. Buck, IVethersfield, Conn. 



Henslow's Sparrow, Ammodraimis hoislsoivii. — I secured an adult 

 female one mile south of Berwyn on October 23, 1896, under somewhat 

 peculiar circumstances. A large black and white cat was seen along the 

 fence of a pasture field, with something in her rrfouth. Through coaxing 

 I rescued the yet living bird from her jaws, without injury to the feathers. 

 It proved to be an old bird in excellent plumage, with the exception of 

 the primaries and secondaries, which were scarcely three-fourths grown. 

 This, together with its extreme fatness, rendered it an easy victim to 

 tabby. Its stomach was filled with a species of wingless Diptera. This 

 is my first personal record of this bird in the state, although I have found 

 it along the coast of New Jersey, where it is less uncommon.

Late Date For Prairie Warbler, Dendroica discolor. — A single in- 

 dividual of this species was observed feeding in a pasture field, and on 

 the bank above a road-side on October 24th, '96, an unu*5ually late date. 

 I succeeded in approaching within four feet and examining it for fully 

 half a minute before it took alarm and flew to a young tree, where it was 

 joined by another of its kind. Frank L. Burns, Bericy}/ Pa.
