408 NATURAL HISTORY. 



Not very abundant at any time, and breeds but sparingly. High, 

 open •woods. Pine and spruce forests. 



74. Dendroica 2^€nnsijlvo.nica, (Linn.,) Bd. — Chestnut-sided Wood- 

 warbler. Spring and autumn visitant. None breed. In spring, from 

 May 1 to 25; in fall, from September 1 to 20. High open woods. 

 Abundant. 



75. Dendroica striata, (Forst.,) Bd. — Black-poll Wood- warbler. 

 Spring and autumn visitant. None breed. In spring, from May 7 

 to June 1 ; in fall, September 7 to second week in October. Arrive 

 latest in both spring and fall, and stay latest of all the migratory 

 warblers. Are the most numerous at both seasons, but especially 

 abundant in the fall. High open woods. 



76. Dendroica aestiva, (Gm.,) Bd. — Summer Yellow Wood-warbler. 

 Summer resident. Very abundant. Breeds in numbers throughout 

 the city, placing the nest in the forks of garden and fruit trees. 

 Arrives April 25; leaves early in September. Never found in high 

 open woods with the other Dendroica, but frequents orchards, gar- 

 dens, &c. ; also swampy copses. 



77. Dendroica maculosa, (Gm.,) Bd. — Black and Yellow Wood- 

 warbler. Spring and autumn visitant. None breed. Arrives first 

 week in May; remains till the third. In fall, from September 1 to 

 October 7. High open woods. Abundant. 



78. Dendroica tigrina, (Gm.,) Bd. — Cape May Wood-warbier. 

 Exceedingly rare. A single specimen obtained September 12, 1859. 

 Times of arrival and departure probably identical with those of D. 

 virens, canadensis, &c. 



79. Dendroica superciUosa, (Bodd,) Bd. — YellQw-throated Wood- 

 warbler. Entirely accidental visitor. One specimen obtained in 

 1842, and now in Smithsonian collection. 



80. Dendroica discolor, (VieilL, ) Bd. — Prairie Wood- warbler. Mostly 

 spring and autumn visitant, being quite abundant during those sea- 

 sons. A few, however, breed. Arrives earlier than most of the 

 DendroicEe, about April 20. Frequents almost exclusively cedar 

 patches and pine trees, and has very peculiar manners and notes. 



81. Dendroica palniarum, (Gm.,) Baird. — Yellow B,ed-poll Wood- 

 warbler. Spring and autumn visitant. Rather rare. None breed. 

 Arrives about May 1; in fall, late in September, and does not leave till 

 middle of October, after all the other warblers but Dend. coronata 

 have taken their departure. Frequents old corn and buckwheat 

 fields, associating with various species of sparrows; differing in this 

 respect from all others of its genus, and resembling Oporornis agilis. 



[There are twenty-two species of Dendroica found in North America; 

 of these, fourteen have been observed here. Not one is a permanent 

 resident; three only (D. pinus, aestiva, discolor) breed; one (D. coro- 

 nata) is a winter resident. Nine others are spring and fall visitants; 

 of these, seven (D. virens, canadensis, blackburniae, castanea, penn- 

 sylvanica, striata, maculosa) do not differ materially in numbers, 

 habits, or times of arrival and departure; one (D. palmai'um) differs 

 in times of arrival and departure, and very remarkably in habits; one 

 (D. superciliosa) is an accidental visitor; one (D. tigriua) is exceed-
