A twittering courser of evening skies who makes his home in our
chimneys. Here the bracket-like nest of dead twigs is attached to the
bricks by the bird's saliva, to be loosened, at times, after heavy rains
and fall to the fire-place below. In the fall great flocks roost in
chimneys, generally large ones, returning night after night.

The 4-6 white eggs are laid in May.

Any Hummingbird seen east of the Mississippi may, with confidence, be
called a Ruby-throat; exceptions will probably prove to be sphinx moths,
which, it must be confessed, look singularly hummingbird-like as they
hover before flowers. When the eggs are laid the male deserts the
female, leaving to her the task of incubation and care of the young.

The nest, most exquisite of bird homes, is saddled to a limb usually 15
or more feet up. The two bean-like white eggs are laid in May.
