INSECTIVOROUS BIRDS. 
This very rare Warbler has only been seen near the 
swamps of Cape May, in New Jersey, and near Philadel- 
phia, about the middle of May, probably as a straggler 
on its way to some northern breeding-place. Its notes 
and further history are yet unknown. 
The length of this bird is 5J inches ; the alar extent 8J. Line 
from the nostril over the eye, chin, and sides of the neck, rich yel- 
low ; the feathers round the ear orange. Wings dusky, edged with 
dark olive yellow. Below bright yellow ; breast and sides under 
the wings, spotted with black; belly and vent yellowish white. Tail 
dusky black and forked, edged with yellow olive. The yellow on 
the throat and sides reaches nearly round it. 
CANADA WARBLER. 
(Sylvia pardalina, Bonap. Muscicapa canadensis , L. Wilson, iii. 
p. 100. pi. 26. fig. 2. [male.] Phil. Museum, No. 6969.) 
Sp. Charact. — Cinereous-brown; crown ash, spotted with black; 
beneath and line over the eyes yellow ; breast with a crescent of 
black spots; tail immaculate. 
This is a very rare summer species in the Atlantic 
States, appearing singly, and for a few days only, on 
their passage north or south in the spring and autumn. 
They probably breed in Canada or Labrador, and are 
more abundant in the mountainous interior, the route by 
which they principally migrate. They winter probably 
in the tropical regions ; are then silent, and, like the 
rest of their tribe, very active in darting through the 
branches after insects. 
This species is only 4J inches long, and 8 in alar extent. Front 
black ; line from the nostril to and around the eye yellow ; below the 
eye a stripe of black, descending along the sides of the throat, which 
with the breast and belly is bright yellow. A broad rounding band
