the Louisiana Water-Thrusli are also limited by the Carolinian 

 Fauna, and are not so common or generally distributed as the species 

 of the first list, though they are plentiful in certain localities. The 

 Prairie, Pine and Parula Warblers summer in considerable numbers, 

 but are almost entirely restricted to the Pine Barren region of New 

 Jersey during the breeding season. The Redstart and Black and 

 White Warbler also breed in small numbers in the southern counties, 

 but become much more abundant northward and towards the 

 mountains. 



Of the transients, the Black-throated Blue, Myrtle, Magnolia, 

 Chestnut-sided, Black-poll, Black-throated Green, Yellow Palm and 

 Canadian Warblers and the Water-Thrush are the most abundant 

 species, and together with the Redstart, Parula and Black and Wliite 

 Warbler (which are partially summer residents) form the bulk of the 

 " Warbler waves " of the migrations. The Nashville, Bay-breasted, 

 Blackburnian, Connecticut and Wilson's Warblers occur regularly, 

 but are not so common, while the Golden-winged, Tennessee, Cape 

 May, Cerulean and Mourning Warblers are decidedly rare. The 

 remaining species can only be regarded as stragglers, i. e., Prothono- 

 tary, Orange-crowned, Townsend's, Audubon's, and Yellow-throated 

 Warblers and Grinnell's Water-Thrush. 



283. Mniotilta van' a (Linn.). Black and White 



Warbler. 



Breeding Range — Eastern N. A., Potomac Valley to Hudson Baj', and 



southward along the Alleghanies. 

 AYiNTEU Distribution — Gulf States to West Indies and northern S. A. 



Abundant migrant in the vicinity of Philadelphia, but rather rare 

 as a summer resident. A few pairs, however, breed regularly in 

 certain localities, and nests have been taken at Haddonfield, N. J. 

 (Ultoads), and in Chester county. Pa. (Jackson). In the New 

 Jersey Pine Barrens it seems to be a more common summer resident, 

 and towards the Alleghanies it steadily becomes a more abundant 

 breeder. 



Occurs at Philadelphia, April 25-May 15 and August 10-Octo-
