NATURAL HISTORY. 
Not very abundant at any time, and breeds but sparingly. High 
open woods. Pine and spruce forests. 
74. Dendroica pennsylvanica , (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, (Gin.,) 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 Dendroicae, but frequents orchards, gar- 
dens, Ac. ; 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-warbler. 
Exceedingly rare. A single specimen obtained September 12, 1859. 
Times of arrival and departure probably identical with those of D. 
virens, canadensis, Ac. 
— 79. Dendroica superciliosa , (Bodd,) Bd. — Yellow- throated Wood- 
warbler. Entirely accidental visitor. One specimen obtained in 
1842, and now in Smithsonian collection. 
80. Dendroica discolor , (Vieill., ) Bd. — Prairie W ood- warbler. Mostly 
spring and autumn visitant, being quite abundant during those sea- 
sons. A few, however, breed. Arrives earlier than most of the 
Dendroicse, about April 20. Frequents almost exclusively cedar 
patches and pine trees, and has very peculiar manners and notes. 
81. Dendroica palmarum , (Gm.,) Baird. — Yellow Red-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 Bend, 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. palmarum) differs 
in times of arrival and departure, and very remarkably in habits; one 
(D. superciliosa) is an accidental visitor; one*(D. tigrina) is exceed-
