strictly migratory Warblers. They are also the most numerous of all, 

 particularly in the fall. High, open woodland, everywhere. In the 

 spring when the Black-polls appear in force we may know that the col- 

 lecting season for Warblers is about over. [122] 



41. (72.) Dendrceca castanea (Wils.) Bd. Bay-breasted Warbler. 



Spring and autumn migrant; none breed here. In spring, May 1 to 

 20; in fall, during the whole month of September, and more numerous 

 than at the other season, for in spring they are not to be entirely de- 

 pended upon. They are usually to be found in high, open woodland, 

 but sometimes in mixed young timber, laurel brakes, &c. [123] 



42. (74.) Dendrceca pennsylvanica (Linn.) Bd. Chestnut-sided Warbler. 

 An abundant spring and autumn migrant; does not breed here. In 



pring, from May 1 to the 25th; in fall, September 1 to the 20th.

Found in high, open woods. In 1882 the little creatures showed their 

 snowy bosoms and pretty chestnut lacings on the streets. [124]

 nolia Warbler. 



An abundant spring and autumn migrant ; does not br,eed here. Ar-

first of September, and does not depart till the second week in Octo- 

 ber. This is another of the beautiful birds which graced the fancy ball 

 we had in '82. [125] 



44. (78.) Dendrceca tigrina {Gm.) Bd. Cape May Warbler. 



Extremely rare; a migrant only, with times of arrival and departure 

 doubtless not peculiar. We obtained a single specimen September 12, 

 1859,- in what was then " Hawes' woods," now opposite the Schiitzenfest 

 Park on Seventh street. This remained a unique occurrence till 1882, 

 when Cape May came to Washington. We saw none actually in the
