12 FIELD COLUMBIAN MUSEUM ORNITHOLOGY, VOL. i. 



15. Geothlypis trichas (Linn.] None were noted during 

 January, and the first specimen secured was on February 2. There 

 was a steady increase in numbers until the middle of March when 

 the species might have been said to be common. There was no 

 appreciable diminution in numbers up to the time of my sailing, 

 May 8. 



16. Microligia palustris Cory. Rare and apparently not 

 found in the interior or on the higher altitudes of the coast district. 

 Frequents the dense thickets, preferably about the swamps, and feeds, 

 I believe, exclusively on insects, in its search for which the actions 

 much resemble those of a Vireo. If the bird has a song I did not 

 hear it, and the only voice is a short contented "cheep," as the 

 little hunter goes in and out among the leaves. It is not at all shy, 

 very readily approached. A breeding female was taken at San 

 Domingo City, April 30. Altogether eight specimens were secured, 

 five from San Domingo City and three from Honduras. 



17. Setophaga ruticilla (Linn.} Tolerably common, and seen 

 at all points visited. 



18. Coereba bananivora (Gmel.} Common, but rather shy 

 and not readily approached. Found on the coast and high up in the 

 mountains, deep in the forest and on the edges of clearings. Has a 

 short little song consisting of some half dozen notes, repeated over 

 and over in the same order. 



I found this species nesting at San Domingo City, February 15. 

 Both male and female worked at carrying nesting material. 



In the series of forty-four specimens before me all the variations 

 in color due to age are well shown. From young birds that are above 

 nearly uniform dusky gray-brown, with yellowish superciliary stripe, 

 and soiled olive yellowish below with a bit of bright yellow in center 

 of breast, we have every intergradation to the fully adult plumage, of 

 dull black above, white superciliary, dark slate-gray throat, bright 

 yellow center of breast and abdomen and grayish olive sides. 



19. Petrochelidon fulva (Vieill). Quite abundant along 

 the coast but not noted in the interior. At San Domingo City 

 breeding birds were taken as early as April 24, and during the same 

 week nesting seemed to be at its height. The nests were all being 

 lined with the soft cottony-like material (called in Spanish America 

 "Balsamo"), that grows in catkins and surrounds the minute seeds 

 of one of the native trees of the country. The birds were going and
