This species arrives early in May and remains until September i. 

 It is a common summer resident of the Lower Hudson Valley, at 

 least as far north as Highland Falls (Mearns). In Connecticut it 

 is common at Saybrook and New Haven, but is rare as far north 

 as Portland where but one or two pairs breed each season (Sage). 

 On Long Island it is known to breed only along the north shore, 

 where it is probably not uncommon in favorable localities. (See 

 Group, Gallery, between Cases M and N.) 



Brewster's Warbler (Helminthophila leucobronchialis) with us is 

 a rare but regular summer resident in northern New Jersey, the 

 Lower Hudson Valley and southern Connecticut, but has been 

 taken only once on Long Island (Howell). Specimens have been 

 recorded from Morristown (Thurber}, Maplewood (Riker), and 

 Englewood, N. J., where it has been found nesting (Chapman, 

 Auk, IV, 1887, p. 348; IX, 1892, p. 302). Farther north in the 

 Hudson Valley it has been found at Nyack (Bicknell\ and at Sing 

 Sing five specimens have been secured (Fisher, Bull. N. O. C , IV, 

 1879, p. 234; VI, 1881, p. 245; Auk, II, 1885, p.. 378). In the 

 Lower Connecticut Valley this bird seems to be more frequent 

 than in any other part of its range. It has been found at Saybrook, 

 Seymour, New Haven, Portland, and other localities, the principal 

 records being as follows: Eames, Auk, V, 1888, p. 427 ; VI, 1889, 

 p. 305 ; Bishop, ibid., VI, 1889, p. 192 ; Sage, ibid., X, 1893, p. 208. 

 Probably not more than one-third of all the specimens recorded 

 are typical leucobronchialis, the remaining two-thirds presenting 

 every stage of intergradation between this bird and typical H.pinus. 



Lawrence's Warbler (Helminthophila lawrencet) is a much rarer 

 bird than the preceding. There are records for only three typical 

 specimens from the immediate vicinity of New York City, viz., 

 Chatham, N. J. (HerricK), Hoboken, N. J. (Lawrence), and Rye, 

 N. Y. (Vorhees, Auk, V, 1888, p. 427). 



Five specimens have been recorded from Connecticut, the 

 details of their capture being given under the references cited for 

 H. leucobronchialis. 



The status of both Brewster's and Lawrence's Warbler 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, i88i,p. 218; Ridgway, Auk, II, 1885, 

 p. 359; Manual N. A. Birds, 1887, p. 486.
