very similar in their habits to swallows?

_Mrs. B._ They belong to the same order, called _hirundines_. There are
four kinds of British _hirundines_:--the house-martin, the swallow, the
swift, and the bank-martin, which have each habits peculiar to
themselves. The swallow is the first that makes its appearance in
spring; generally about the middle of April. It frequently builds in
chimneys, five or six feet from the top, and prefers those stacks where
there is a constant fire; no doubt, for the sake of the warmth. It does
not select the immediate shaft where there is a fire, but prefers one
adjoining the kitchen, and disregards the smoke by which it is almost
continually enveloped. The nest of the swallow, like that of the house-
martin, consists of a shell, composed of dirt or mud, mixed with short
pieces of straw to strengthen it. The shape is, however, somewhat
different: it is lined with fine grass and feathers, which are collected
by the little architects as they float in the air. Having constructed
their dwelling, the hen lays from four to six white eggs, dotted with
red specks, and brings out her first brood about the last week in June.
I have been frequently amused in watching the progressive method by
which the young ones are introduced into life: they first emerge from
their place of concealment with difficulty, and frequently I have found
a young one in the parlour, which had fallen down the chimney in its
first attempt to leave the next. For a day or two, the old ones feed
them on the chimney-top, after which, they conduct them to the dead
bough of some tree near at hand, where they continue attending them with
the greatest assiduity. In a few days after this, the young brood is
enabled to fly, but it is some time longer before the little creatures
can take their own food; until which time, they are fed by the parent
birds, with the most affectionate solicitude. As soon as they are
disengaged from their necessary attendance on their first brood, they
