THE BIRDS OF HAITI AND THE DOMINICAN REPUBLIC 387 



ary 25, Pont Sonde, February 27, and Cerca-la-Source, March 24 and 

 27, 1929. On Gonave Island specimens were shot at En Cafe, March 

 4, 6 and 7, Massacrin, March 9, and Plaine Mapou, March 11, 1929. 

 Birds from Gonave are in partial molt on the throat. 



The prairie warbler is among the smallest species of its genus and 

 though brightly colored is sometimes identified with difficulty by the 

 novice. Above it is bright yellowish green with a slight mixture of 

 chestnut, often nearly concealed, in the center of the back that marks 

 it from its relatives. There is a light bar more or less evident in the 

 wing, and the outer tail feathers are prominently white. Below it is 

 bright yellow, this color covering the sides of the head and forming 

 a line above the eye. There is a heavy black mark on the side of the 

 head well below the eye, and prominent black streakings on the sides. 

 The female is somewhat duller than the male. 



[DENDROICA PENSYLVANICA (Linnaeus) 

 CHESTNUT-SIDED WARBLER 



Motacilla pensylvanica Linnaeus, Syst. Nat., ed. 12, vol. 1, 1766, p. 333 

 (near Philadelphia, Pa). 



Dendroica pensylvanica, Baetsch, Proc. Biol. Soc. Washington, vol. 30, July 

 27, 1917, p. 132 (listed from Haiti). 



Paul Bartsch recorded this species as seen at Port-au-Prince and 

 St. Marc April 21 and 22, 1917, but as no specimens were taken and 

 the species is not recorded from the West Indies, (except casually 

 from the Bahamas), its southward migrations carrying it to the 

 southwest through eastern Mexico, it is here included in the hypo- 

 thetical list. 



It is of usual warbler size as found in this genus, and is marked 

 in breeding plumage by bright yellow crown and a chestnut streak 

 on the sides, being otherwise pure white below. Immature birds are 

 clear white below, and above are yellowish green indistinctly streaked 

 with blackish.]

Winter migrant from North America; apparently rare. 



The black-poll warbler so far as known was first obtained in His- 

 paniola by Kaempfer, who secured three specimens in the Yuna 

 swamps on October 8, 18, and 22, 1922. We are indebted to Ernst
