The young bird of the year is notably smaller, and has
still less of the red-chestnut tint than the adult female;
the hack, wings, and neck, are of two shades of brown, the
edges of the feathers being of the lighter colour ; breast and
belly dull brownish-grey.
In a nestling lent to the Editor by Mr. E. Bidwell, the
dark brown of the crown of the head, hind-neck and upper
parts, is very sharply defined against the clear yellowish-
buff of the cheeks, front of the neck, and breast; flanks
dark brown. As a rule, nestlings of the Diving Ducks may
be distinguished from those of the Anatince by the absence
of light spots on the hack; but the young of the Ferruginous
Duck shows a distinct bar of lighter colour on the pinion
and the adjacent portion of the body.
The trachea of the male is about six inches in length ;
the tube is small at both ends, hut enlarged in the middle;
the portion represented below is of the natural size.

THE SCAUP DUCK.
Fuligula marila.
T h e S caup D uck is a winter visitor to this country, and
rather a late one, seldom making its appearance till the
end of October, or the beginning of November. About that
time, particularly if the weather he rough and cold, small
flocks arrive on various parts of the coast and at the mouths
of rivers, hut do not often visit the waters of inland counties.
They appear to prefer low, flat, muddy, or oozy shores, and
are often numerous throughout the winter months on such
portions of our coasts, where, in company with Tufted
Ducks, Golden-eyes, and other species, they are sometimes
pursued by wild-fowl shooters in their gunning-punts, and
also occasionally caught by fishermen in upright nets fixed
in curving lines on perpendicular stakes in shallow hays.
