2 J. Richmond. Birds Breeding in District of Columbia. [January 



posed of skeleton leaves, and the lining was of hair moss {Polytric/inm'). 

 On the 14th of June the same year, another nest, containin_£^ five young 

 birds half-Hedged. \va.s found in the same locality. The next year a deserted 

 nest was found, corresponding in size and material with the other two. 

 June 5, 18S7, Mr. M. Thompson found a nest with five half-grown young. 

 The nest was on a hillside facing the west, as were the other three, and 

 was composed of like materials. 



77. Helminthophila pinus. Hlue-wixged Warbi.er. — Extremely 

 rare. Mr. Herman II. Birney found a nest containing four eggs about to 

 hatch, early in June, 1S80. This is probably the only known instance of 

 its occurrence here during the breeding season. 



78. Compsothlypis americana. Parula Warbler. — Rare. Heard a 

 male singing June 10, 1886, and watched it for sometime, hoping it would 

 give me information regarding the whereabouts of its nest, something it 

 firmly declined to do. 



79. Dendroica aestiva. Yellow Warbler. — Common. 



So. Dendroica vigorsii. Pine Warbler.- — Very rare in summer. 



81. Dendroica discolor. Prairie Warbler. — Common. The nest is 

 very difficult to find. 



82. Seiurus aurocapillus. Oven-bird. — Abundant. Begins nesting 

 about the last week in May ; eggs four or five. 



S3. Seiurus motacilla. Louisiana Water-Thrush. — Uncommon. 



84. Geothlypis formosa. Kentucky Warbler. — Rare. Mr. Henshavv 

 has found the nest here, and I have found young birds hardly able to fly. 



85. Geothlypis trichas. Maryland Yellow-throat. — Abundant. 



86. Icteria virens. Yellovv-breastkd Chat. — Common. Begins 

 nesting last week in May. 



87. Setophaga ruticilla. American Redstart. — Rather common. 



88. Mimus polyglottus. Mockingbird.— Rare. 



89. Galeoscoptes carolinensis. Catbird. — Very abundant. Com- 

 mences nesting about the middle of May ; eggs four or five. 



90. Harporhynchus rufus. Brown Thrasher. — Moderately abuntiant. 

 Begins nesting about two weeks earlier than the preceding. The nest is 

 sometimes found on the ground. 



91. Thryothorus ludovicianus. Carolina Wren. — Common. An 

 early breeder. After leaving the nest the 3'oung birds continue with the 

 old for some time. 



92. Troglodytes aedon. House Wren. — Very common. A nest found 

 atDunn-Loring, Va., by Mr. J. D. P'iggins, was built inside of a deserted 

 Barn Swallow's nest, and contained seven eggs. 



93. Cistothorus palustris. Long-billed Marsh Wren. — Very nu- 

 merous. Breeds abundantly in all the marshes around Washington. Dr. 

 Coues, in his "Birds of the Northwest,' speaks as follows on the nidification 

 of the Marsh Wren: "The eggs, as usual, are numerous — ^ six or eight — 

 sometimes so many as to induce the suspicion that the\- were not all laid 

 by the same bird." This can hardly apply to the birds around here, as 

 I have ex imined a great many nests just for the sake of finding a large 

 set, and have never found more than five eggs or young in one nest.
