lO THE AMERICAN MIDLAND NATURALIST 



There is but a single record for this species, and that on May 

 30, 191 7, which, with a single exception, June 5, 191 7, is the latest 

 for the vicinity of Washington. 



68. Dendroica pensylvanica. Chestnut-sided Warbler. 

 Of this warbler we saw but one, on an unknown date. 



69. Dendroica fusca. Blackburnian Warbler. 



Our single record is October 6, 191 6, which is uncommonly late 

 for the species in the region about Washington, since its latest 

 date is October 7, 1889. 



70. Dendroica virens. Black-throated Green .Warbler. 



For this pretty little warbler we have only a few records, which 

 are as follows: April 30, 1914; September 17, 21, and 26, 1916. 



71. Dendroica coronata coronata. Myrtle Warbler. 



For so common a species we have surprisingly few notes, as 

 follows: May i and 2, 1915; May 25, 1917; and October 4, 1914. 

 That for May 25 is later than any published date for the species 

 about Washington, the previous latest being May 23, 1903, although 

 there is an unpublished record for May 30, 191 7. 



72. Dendroica caerulescens caerulescens. Black- throated Blue 

 Warbler. 



Three instances: May 25 and 27, 1915, and another without 

 specific date. 



73. Dendroica tigrina. Cape May Warbler. 



This is one of the warblers that has recently much increased in 

 numbers in the vicinity of Washington. It was not noted in our 

 yard until September 21, 191 6, and was more or less common 

 until October 9 of that year; as many as five sometimes being seen 

 within a few minutes. We have only two subsequent records, 

 May 24, 191 7, and October 8, 191 7. It frequented both the trees 

 along the street and those in the back yards. 



74. Dendroica magnolia. Magnolia Warbler. 



Identified on only three occasions: September 21, 1916; Septem- 

 ber 21, 191 7; and October 8, 1916. 



75. Dendroica aestiva aestiva. Yellow Warbler. 



For so common a bird it was rather remarkably seldom seen ; 

 but it apparently does not come into the city so numerous as 

 some other warblers. Our only records are: May 16 and 21, 

 1915; May 24, 1914; and June 11, 1916.
