the flycatchers, from about May 8 to 25, and again from August 20 to 

 September 10. 



203 (686). Canadian Warbler. Wilsonia canadensis 

 {Linn.^. 



A common migrant, especially in the low wet woods along the Mill- 

 stone and Stony Brook, from May 6 to 30, and later from August 15 to 

 September 25. 



204 (687). American Redstart. Setophaga ruticilla 



A very common migrant and not infrequent summer resident. I 

 have never found the nest of this species, but on two occasions I have 

 seen pairs carrying the materials for building. Prof. Phillips, however, 

 has been more successful having found two nests June 6, 1901, one of 

 which contained three eggs. The birds may be found from April 28 

 until October 10. 



Family Motacillidse. Wagtails and Pipits. 



205 (697). American Pipit; Titlark. Anthus pen- 

 silvanicus {Lath.'). 



Flocks of these birds appear on open fields and pastures at inter- 

 vals during the three spring months and again during October and 

 November. 



Family Troglodytidae. Thrashers, Wrens, etc. 



206 (703). Mockingbird. Mimus polyglottos {Linn.). 



A very rare summer resident. Prof. Phillips has taken a single 

 individual. It was a young bird, probably reared in the neighbor- 

 hood. 



207 (704.) Catbird. Galeoscoptes carolinensis {Linn.). 



A very abundant summer resident, arriving with great regularity 

 the third week in April, and remaining until October 22. A large 

 majority of the nests found have contained fresh eggs the third week in 

 May.
