Birds of Princeton. I 



is not uncommon, frequenting the low swampy lands near ponds and 

 marshes. 



198 (679). Mourning Warbler. Geothlypis Phila- 

 delphia {Wils.). 



A very rare migrant. The only record for its occurrence in this 

 locality is for September 22, 1880, when Mr. Scott secured a female 

 which is at present in the University Collection, No. 6942. 



199 (681). Maryland Yellowthroat. Geothlypis 

 trichas {Linn?). 



This is one of the most abundant warblers, breeding in damp 

 thickets and along the edges of every bog or marsh in the neighbor- 

 hood. As many as sixteen nests have come under my observation and, 

 although the majority were in tussocks of grass in the immediate prox- 

 imity of water, yet quite a number have been found in dry thickets and 

 briar patches suspended several inches above the ground. The eggs 

 are generally laid early in June, but I have frequently found nests in 

 May, and on one occasion a set of eggs was taken May 19. The birds 

 may be found here from April 24 to October 21. 



200 (683). Yellow-breasted Chat. Icteria virens 



{Linn.y 



The Chat is here a common summer resident, breeding in many of 

 the briar patches on Mount Lucas and in the swamps of the Millstone. 

 In this locality the eggs are laid generally the fourth week in May. 

 The birds arrive about May i, and remain until September i. 



201 (684). Hooded Warbler. Wilsonia mitrata 

 {Gmel.^. 



A species of casual occurrence. Several years ago Prof. Phillips 

 saw a small flock during May. On May 5, 1900, Mr. C. R. Babson 

 saw one which he was unable to secure. Mr. Scott secured a specimen 

 May 2, 1881, No. 2209, University Collection. 



202 (685). Wilson's Warbler. Wilsonia pusilla 

 {IVi/s.). 



A regular and not uncommon migrant, frequenting the lower wood- 

 land growths, where it catches its insect food much after the manner of
