No. I I Birds of Frinceton.

213 (725). Long-billed Marsh Wren. Cistothorus 

 palustris ( Wt/s.). 



A rather uncommon and very local summer resident and migrant. 

 I have never found this species breeding in the immediate neighbor- 

 hood of Princeton, but Prof. Phillips tells me that a few nest at the 

 Duck Pond every year. In the marshes of the Delaware near Trenton 

 I have found this wren to be a common summer resident. Four nests 

 which I have seen contained fresh eggs the second week in June. The 

 birds arrive about May 7 and remain until October 15. 



Family Certhiidae. Creepers. 



214 (726). Brown Creeper. Certhia familiaris ameri- 

 canus {Bonap.^. 



A much more common migrant and winter resident than is gener- 

 ally supposed. During the season of 1899-1900 I noticed this species 

 more than thirty times. It may be found from September 28 until 

 April 20, and is especially abundant during the migrations. 



Family Paridae. Nuthatches and Titmice. 



215 (727). White-breasted Nuthatch. Sitta caro- 

 linensis Lath. 



A not uncommon resident, but much more frequently seen during 

 the colder months when they rove around in small bands. About April 

 I these nuthatches seem to disappear, and during the breeding season 

 are quite rare, only a few nests having been found. Mr. Benjamin 

 Gray found one early in May 1900. I am inclined to think that many 

 of the fall and winter birds are visitors from the north. 



216 (728). Red-bellied Nuthatch. Sitta canadensis 

 Lznn. 



A winter visitor very erratic in occurrence. At intervals of some 

 years this species appears in considerable numbers from the north, and 

 at other seasons is either very rare or entirely absent. During the 

 winter of 1899- 1900, which was especially mild, these nuthatches were 

 abundant, travelling through the town in bands of twenty or thirty and 

 remaining in some instances as late as May 13. On that date two pairs
