49. Setophaga ruticilla (Linnseus). Redstart. — Fairly common as 

 a winter visitant; more abundant during migration. Mr. Bowdish (1902- 



3, p. 19) noted redstarts on November 30, 1899, and I found them here 

 until the time of my departure (April 4). On March 27 they were abun- 

 dant. 



50. Seiiirus motacilla (Vieillot). Louisl\na Water-Thrush. — A 

 winter visitant. One or two were seen occasionally up to March 27. Mr. 

 Bowdish (1902-3, p. 19) secured specimens on December 27, 1899, and 

 January 22, 1900. Mr. A. B. Baker of the " Fishhawk " secured a female 

 on February 7, 1899. 



51. Seiurus aurocapillus (Linnseus). Ovenbird. — A tolerably 

 common winter visitant more common apparently during migration. 

 Ovenbirds frequented the ground in sheltered areas in the dry thickets 

 and when flushed went up into the bushes but in a few minutes dropped 

 down and began feeding, again. On March 19 and again on IXlarch 27 

 they were especially common. They were not observed after the latter 

 date. One specimen secured was verj^ pale in color. Birds were taken on 

 March 19 and 20. 



52. Dendroica discolor (Vieillot). Prairie Warbler. — A common 

 winter visitant. Dry lirushy areas seemed especially suited to these 

 warblers. They were found feeding on the ground in the thickets or work- 

 ing quickly through the smaller branches. On March 19 and 27 they were 

 especially common and were then in migration. Small flocks or single 

 birds were observed during these days always working steadily to the west- 

 ward. They were present in numbers to the time of mj^ departure on April 



4. Specimens were secured on March 19 and 25. 



53. Dendroica adelaidae Baird. Adelaide's Warbler. — A fairly 

 common resident on Vieques Island. As noted previously (Wetmore, 

 1916, p. 103) this species was not known until 1912 outside of Porto Rico. 

 The birds were locally common in the brush gi'own vallej's on the northern 

 side of the island and in the hot dry region of the south coast. The}^ 

 worked actively through the dense tangles of vines, the males giving their 

 loud triUing songs frequently, but were difficult to locate. In the bushes 

 they fed near the ground occasionally dropping down to the earth after an 

 insect that had eluded capture in the limbs above. The fu'st pair taken on 

 March 20 were in worn breeding plumage but others taken later were in 

 better condition, though all were breeding or about to do so. Others were 

 taken on March 21 and 25. Specimens from Vieques Island differ in no 

 way from the larger series secured on Porto Rico. 



54. Dendroica coronata (Linnseus). Myrtle Warbler. — A toler- 

 ably common winter visitant. Mr. Bowdish (1902-3, p. 18) secured 

 specimens on January 22 and 30, 1900, and I saw one in the town of Isabel 

 II on April 1, 1912. 



55. Dendroica caerulescens cserulescens (Gmelin). Black- 

 throated Blue Warbler. — A male was observed but not taken on 

 March 27, 1912. There is no other record for this bird. It probably 

 occurs with more or less regularity during migration.
