The chopì, which is about the size of a swallow, and has dusky feathers,
but if shone upon by the sun, of a blue colour, goes in flocks like
European sparrows, flies up and down houses, and wheat fields, and
delights the ear with its pleasing song. Some very small birds, the
names of which I am unacquainted with, sing sweetly in gardens, but when
taken they cannot long bear the confinement of a cage.
