the yard of a neighbor. " It appears to have been plentiful in for- 

 mer years, and, according to Bartram and Dr. Barton, even re- 

 mained all the winter near Philadelphia " (Turnbull). 



Catbird. Galeoscoptes Carolinensis. 



Abundant everywhere. I think it is evident that a change is 

 slowly coming over their migratory habits. They certainly arrive 

 earlier and stay later than the dates mentioned by Wilson, Audubon, 

 or Nuttall. Single birds have been seen during the winter. 



Bluebird. Sialia sialis. 



Whatever may have been the habit of this species, it is now, in 

 no sense, migratory. 



Golden-crowned Knight. Regulus satrapa. 



Not uncommon. Seen both in spring and autumn usually ; but 

 also in winter, though less frequently. That they breed in Northern 

 New Jersey is unquestionable. 



Ruby-crowned Wren. Regulus calendula. 



More abundant than the preceding, and is identical in all its 

 habits. The two are frequently associated, especially in mid- winter, 

 when a flock of a dozen or twenty is occasionally met with. 



Blue-gray Gnat-catcher. Polioptila ccerulea. 



I have seldom met with this species, which can scarcely be rec- 

 ognized by a description of its voice, quoted by Jordan as " like 

 a mouse with the toothache." It is said, on the contrary, to be 

 really a fine singer. Dr. Turnbull does not give this species in his 

 list. 



Tufted Tit. Lophophanes 'bicolor. 



Abundant. " Especially abundant in summer " (Turnbull). My 

 observations have led me to conclude it was more common in au- 

 tumn and winter than in summer. 



Black-capped Tit. Parus atricapillus. 



Very abundant. During the summer they are more retiring in 

 their habits and stay more closely in heavily-timbered areas. In 

 winter they at times almost outnumber the snow-birds. 



White-bellied Nut-Hatch. Sitta Carolinensis. 



Common. While to be found, on careful search, at any time of 

 the year, they are certainly more abundant during the winter.
