179. WHOOPER SWAN. _Olor cygnus._

This European variety frequently is found in Greenland and formerly,
regularly bred there. It nests in secluded swampy places in northern
Europe.

180. WHISTLING SWAN. _Olor columbianus._.

Range.--North America, breeding in the Arctic Circle, and wintering
south to the Gulf of Mexico.

These birds, which are nearly five feet in length, are snow white with
the exception of the black bill and feet. The Whistling Swan is
distinguished from the next species by the presence of a small yellow
spot on either side of the bill near its base. Their nests are made of a
large mass of rubbish, weeds, grass, moss, feathers and occasionally a
few sticks. It is generally placed in a somewhat marshy place in the
neighborhood of some isolated pond. The eggs are of a greenish or
brownish buff color, and number from three to six. Size 4.00 x 2.75.
Data.--Mackenzie River. Nest a mass of weeds, sods and grass, lined with
feathers; on an island near the mouth of the river. Collector, I. O.
Stringer.

181. TRUMPETER SWAN. _Olor buccinator._

Range.--Interior of North America from the Gulf of Mexico northward,
breeding from northern United States northward.

This is a magnificent bird, about five and one-half feet in length. Its
plumage is exactly like that of the preceding except that the bill is
entirely black, and the nostril is located nearer the eye. Their nesting
habits and eggs are the same as those of the Whistling Swan. While a few
pairs may breed within the United States by far the greater number are
found in the extreme north, from Hudson Bay to Alaska. The eggs may
average a trifle larger than those of the preceding species.
