Diimetella carolinensis. Catbird. — This abundant summer 

 resident was one of the species seen daily, both on the dunes 

 and in the woods. At Birchwood Beach it was recorded in 

 July, August, and September, 1917, and after May 3, 1918; 

 at Warren Woods after May 7, 1919; and at Warren Dunes 

 after May i, 1920. The catbird is largely a ground species 

 inhabiting hedge-rows and thickets. At the dunes the writer 

 found them in May, 1920, feeding daily on the seeds of the 

 sumach. 



Toxostoma rufum. Brown Thrasher. — This common sum- 

 mer resident was seen at Birchwood Beach from July to Sep- 

 tember, 1917, and after April 29, 1918. At Warren Woods 

 it was not so common, but there were a few after May 4, 



1919, and at Warren Dunes after April 29, 1920. This also 

 is a ground lover; it frequents brush piles and hedge-rows 

 during the day, but sings from the tree tops at early morning 

 and evening. 



Troglodytes a'edon aedon. House Wren. — A very abundant 

 summer resident, especially about the resorts. A dozen pairs 

 or more nested at Birchwood Beach in the cottages and nest 

 boxes put up by Mr. Sizer, and although this colony was so 

 closely associated, no trouble was noticed as the result. April 

 29, 1918, at Birchwood Beach, is our earliest record. In 1919, 

 at Warren Woods it was not so common, but was noted each 

 day after May 4 in the deep woods as well as about the build- 

 ings. At Warren Dunes many pairs were seen after April 2, 



1920, often in the thick woods. 



Nannus hiemalis hiemalis. Winter Wren — A rather rare 

 migrant. Only two or three were seen at Birchwood Beach 

 from April 29 to May 7, 1918. At Warren Woods only one 

 "was noted May 12, 19 19, about an old wood-pile. At Warren 

 Dunes it was rare, being recorded only on April 29, 1920.
