2 7 2 Ralph and Bagg Birds of Oneida County, Nezv York. [July 



Dendroica vigorsii. — June II, 1SS9, at Sylvan Beach, we saw at least two 

 pairs building in high pines. We watched them, with a glass and the 

 naked eye, collecting spiders' nests from under the veranda of a cottage 

 and carrying these and other materials into two places in the pines. A 

 day or so afterwards a gang of men moved a neighboring cottage a tew 

 feet, cutting two trees near those in which the birds were building, and the 

 birds disappeared. About two weeks later a single bird was seen at the 

 same place. This species was given in the List on the strength of the 

 single specimen given by Dr. Merriam, in his 'Preliminary List of the 

 Birds of the Adirondack Region,' as taken at Lyon's Falls. It must now 

 be given as a rare summer resident, breeding. 



Dendroica palmarum. — Given in the List on the authority of Dr. Mer- 

 riam. Mr. Shepard has taken three specimens, two near Clinton, May 3 

 and 9, iSSS, and one at Sylvan Beach, Oct. 5, 1SS9. 



Troglodytes aedon. — Perhaps the strangest observation we have to re- 

 cord is the entire disappearance of this species which was ten or fifteen 

 years ago one of our most abundant species, nesting in dozens of bird 

 houses in the city and in every empty shed and wooden bridge in the 

 country. In the List it is given as "a summer resident, not nearly so 

 common as formerly, breeds." Since that was written four years have 

 passed during which, of the four workers whose observations are here re- 

 corded, only one has seen a single specimen of this bird. Since 1SS7 not 

 a single one has been observed. We are unable even to suggest an ex- 

 planation of this mystery. 



Troglodytes hiemalis. — We have taken two more nests of this species, 

 June 2S and 29, 1SS7, at Holland Patent and Trenton Falls. They 

 were placed and constructed almost exactly as the one described in the 

 List, and contained four and six fresh eggs respectively. 



Certhia familiaris americana. — Since the nest described in the List, we 

 have taken three more, all near Holland Patent, and each placed under a 

 loose piece of bark beside the trunk of a dead tree. The first was taken 

 June 15, iSSS, and contained four young birds ready to fly and two addled 

 eggs. The second was taken June 21, 18S8, and contained five nearly 

 fresh eggs. The third, taken June 30, iSSS, contained six fresh eggs. 



Sitta canadensis. — A common migrant; summer resident in the north- 

 ern part of the County. Breeds. A second nest, taken May 30, 1S87, 

 in Wilmurt, Herkimer Co., contained six fresh eggs. 



Parus hudsonicus. — A specimen was killed by Mr. Hughes at Rem- 

 sen, Dec. 25, 1SS6. This species was given in the List on the authority of 

 Dr. Merriam. 



Regulus satrapa. — Given in the List as "a common migrant." To this 

 must be added: — An occasional resident, both winter and summer; 

 breeds. — A specimen was taken by Messrs. Hughes and Shepard at the 

 same time and place as the preceding, and they also report that they 

 have found them other winters. During the latter part of June, iSSS, near 

 Holland Patent we observed a pair of these birds followed by seven or eight 

 young which they were feeding.
