DENDROICA DOMINICA. Yellow-throated Warbler. 



The Yellow-throated Warbler is properly a bird of the south 

 Atlantic States not known to breed north of Virginia, but it occa- 

 sionally wanders to the Middle States and New England. Several 

 specimens are recorded for Connecticut (cf. Merriam, Rev. Birds 

 Conn., 1877, p. 17), and one was taken on the banks of Charles 

 River in Dedham, Massachusetts, about the year 1868 (Purdie, 

 Bull. N. O. C., Vol. Ill, 1878, p. 146). 



DENDROICA PALMARUM. Palm Warbler. 



Although Mr. Minot gave both the above names in the original 

 edition, his description and biography relate wholly to the Yellow 

 Palm Warbler (D. p. hypochrysea), a strongly characterized sub- 

 species first described by Mr. Ridgway (Bull. N. O. C., Vol. I, Nov., 

 1876, p. 85). The two forms differ as follows : 



D. palmarum. Smaller, the upper parts duller and grayer, the 

 yellow of the lower parts bright and continuous only on the throat, 

 chest, and under tail-coverts of mature birds. Young in autumn 

 and winter have the superciliary stripe dull whitish, the lower parts 

 (except the under tail-coverts, which are always yellow) brownish 

 white (sometimes with a tinge of yellow), the chest and sides 

 streaked with grayish brown. 



D. p. hypochrysea. Larger and more richly colored, the ground 

 color of the entire under parts bright yellow at all ages and seasons, 

 save in the nestling or first plumage. 



The Yellow Palm Warbler, as already stated (see foot-note on page 

 124 of this edition), breeds sparingly in eastern Maine, rather numer- 

 ously in New Brunswick and Nova Scotia and northward to Hudson 

 Bay. It occurs commonly throughout most of New England dur- 

 ing its northward as well as southward migrations. D. palmarum 

 is supposed to breed only in the interior of North America (as far 

 north at least as Great Slave Lake). I am not aware that it has ever 

 been taken in New England in spring, but in autumn it visits us 

 quite regularly, appearing the last week of September, and hence a 

 little in advance of its near relation D. p. hypochrysea^ with which it 

 sometimes associates in early October, although usually, according to 

 my experience, it is found apart from the latter and either singly or 

 in little family parties of from two to four birds each. Although 

 perhaps never present in sufficient numbers to be called common it 

 is, on the other hand, by no means rare, for a good collector may 

 easily take several specimens in a single season provided he looks
