104 THE NATURALIST’S GUIDE. 
bler. Very abundant spring and autumn migrant. I have 
taken it in spring from May 15th until June 9th; in au- 
tumn, from September 19th until the latter part of Oc- 
tober, — during this season it is very numerous. I think 
the Sylvia autumnalis, Wils., 1s really the young of this 
species. I have shot hundreds of this species in autumn, 
but have never taken one of the other (D. castanea). 
42. Dendroeca cestiva, Bairp.— Summer Yellow- 
Bird. The most common of the Derdreca in summer ; 
breeds abundantly. Arrives from April 30th to May 8th ; 
departs early in September. 
43. Dendrceca maculosa, Bairp.— Black and Yellow 
Warbler. Rather rare wizrant, although: common during 
the spring of 1857. Arrives the third week in May; have 
taken it from the 23 to the 27th; have never met with it 
in autumn. Frequents the woods everywhere.

bler, “Palm Warbler.’ Abnudant during the migrations.

arrives from the north about the middle of September, and 
occupies about two weeks in passing. The most terres- 
trial of all the Dendiw.a. Found everywhere. '

Rather common summer resident. Arrives from May 13th 
to 19th. Frequents the high sandy fields grown up to 
bushes, or rocky hillside covered with barberry bushes, 
where it. breeds. Has a most peculiar song, which is al- 
most indescribable. 
I have never met with the Blue Warbler (Dendreca 
cerulea, Baird) although it perhaps rarely occurs. 
46. Perissoglossa tigrina, Bairp. — Cape May War- 
bler. Exceedingly rare spring and autumn migrant. I 
have never met with it. Mr. W. Brewster has taken it 
in an apple-tree on May 17, 1867. The late Dr. Henry 
Bryant once showed me quite a number of skins, which he
