twig and occasionally coming down to the tall weed stalks. The usual 

 call is the familiar "chick-a-dee, chick-a-dee-dee-dee," while in the 

 nesting and breeding season there is the clear whistle "tee dee," the 

 first a high note, the second much lower. 



In the vicinity of Princeton and Haddonfield, and probably else- 

 where in south Jersey, the Chickadee occurs in winter along with the 

 resident Carolina Chickadee. 



736 Penthestes carolinensis (Audubon). 

 Carolina Chickadee. 



Adults. Length, 4.25-4.50. Wing, 2.45. Coloration like the preceding 

 species, but the wing and tail edgings narrower and grayer, never pure white. 

 Nest and eggs similar to those of the Black-cap ; size, .53 x .43. 



Common resident throughout southern New Jersey, north to 

 Princeton, but more plentiful in the pine barrens than elsewhere. 



This is the Chickadee of the southern half of the State and a char- 

 acteristic bird of the pine barrens. In habit, as in coloration, it re- 

 sembles the Black-cap : the notes are similar but the "chick-a-dee" is 

 said to be higher pitched, while the whistle is lower.
