within a few feet of it, at the foot of the
tree, on which it is gathering its food.
Early in October these birds are seen
roving restlessly through the woods, pre-
paratory to their departure for the south.
They have a simple, plaintive, and some-
what drawling song, resembling the syl-
lables “ te de teritsca,” pronounced pretty
loud and slow. They often build their
nests in the juniper tree, using strips of
juniper bark for that purpose. The eggs
are usually four in number, white, spotted
with purple and brown.
