Lawrence's Warbler {Helminthophila lazvrencci) is a much rarer bird 

 than the preceding. There are records for only six specimens from the imme- 

 diate vicinity of New York City, viz. Chatham, N. J. (Herrick), Hoboken, N. 

 J. (Lawrence), Rye, N. Y. (Vorhees, Auk, V, 1888, p. 427), Greenwich, Conn. 

 (Vorhees, Auk, XI, 1894, P- 259), Cold Spring Harbor, L. L (Braislin, Auk, XX, 



1903, p. 53), and New York Zoological Park, where a male was found breeding 

 with a female piims (Bildersee, Bird Lore, VI, 1904, p. 131 ; Beebe, Auk, XXI, 



1904. p. 387). 



The status of both Brewster's and Lawrence's Warblers is still unsettled. 

 They are generally considered to be hybrids between H. pinus and H. chrysoptera, 

 and it has also been suggested that dichromatism may play a part in producing 

 their coloration. Their relationship will be found discussed under the following 

 references: Brewster, Bull. N. O. C, VI, 1881, p. 218; Ridgway, Auk, II, 1885, 

 p. 359; Manual N. A. Birds, 1887, p. 486; Birds of North and Middle America, 

 II, 1902, pp. 452, 453: Thayer, Auk, XIX, 1902, p. 401 ; Bishop, Auk, XXII, 1905, 

 p. 21). 



*Golden-winged Warbler {Helminthophila chrysoptera). In the immediate 

 vicinity of New York City, this bird occurs as a rather rare spring migrant, but 

 in the early southward migration, in August, it is sometimes not uncommon. It 

 has been found nesting at Nyack, N. Y. (Brownell) and probably breeds regu- 

 larly from that point northward. 



♦Nashville Warbler (Heliiiintliophila rubricapilla). This species is here a 

 rather common migrant and a rare summer resident as far south as Highland 

 Falls. It arrives about May 10 and returns on its southward journey during late 

 August, the last migrants being seen about September 25. A breeding female 

 was taken by Chapman at Englewood, N. J., June 16, 1887, (Auk, VI, 1889, p. 

 304). 



Orange-crowned Warbler (Helminthophila celata). This Warbler occurs 

 here as an exceedingly rare migrant. There are records of only six specimens, 

 all but one of which occurred in the fall. (Howell, Auk, X, 1893, p. 91). 



♦Tennessee V/arhlcT (Helminthophila peregrina). With us this bird is a 

 rather rare spring migrant but is sometimes not uncommon in the fall. It passes 

 northward early in May and returns on its southward journey in September. 



♦Northern Parula Warbler (Compsothlypis americana usnece). The Parula 

 Warbler is here a more or less abundant migrant and local summer resident. 

 It arrives from the south about May 7 and the last individuals are observed in 

 early October. 



*Cape May Warbler (Dcndroica tigrina). This is one of our rarest spring 

 migrants, passing northward about May 15. In the fall migration immature 

 birds are sometimes not uncommon. 



*Yellow Warbler (Drn(/ro(Va <r.yfn'o). A common summer resident. It 

 ai rives from the south about May 5 and remains until September. (See group, 

 third floor).
