these were, I conjecture, young birds, as they were brown, not black; but
they had the _white_ on the rump, which is characteristic of the species.
A few days afterwards I observed several _Martin's_ nests in a blind
window on Islington-Green. And, Sept. 20, of the same year, I saw from
the window of my present residence, in Dalby Terrace, City Road, many
similar birds actively on the wing.

The _Redbreast_ has been, I am told, occasionally seen in the
neighbourhood of Fleet-market and Ludgate-hill. I saw it myself before
the window of my present residence, Dalby Terrace, in November, 1825, and
in Nov. 1826, the _Wren_ was seen on the shrubs in the garden before the
house at Dalby Terrace; it was very lively and active, and uttered its
peculiar _chit, chit_.

The _Starling_ builds on the tower at Canonbury, in Islington; and the
_Baltimore Oriole_ is, according to Wilson, found very often on the trees
in some of the American cities; but the _Mocking-bird_, that used to be
very common in the American suburban regions, is, it is said, now
becoming more rare, particularly in the neighbourhood of Philadelphia.

The _Thrush_ was also often heard in the gardens behind York-place,
during the spring of 1826. I heard it myself in delightful song early in
March, 1826, among the trees near the canal, on the north side of the
Regent's Park.

Some of the migratory birds approach much nearer to London than is
generally imagined. The _Cuckoo_ and _Wood-pigeon_ are heard occasionally
in Kensington-gardens. The _Nightingale_ approaches also much nearer to
London than has been commonly supposed. I heard it in melodious song at
seven o'clock in the morning, in the wood near Hornsey-wood House, May
