360 THROUGH T H E MACKENZIE BASIN
There are no eggs, but four fine specimen skins, of the
golden eagle in the Dominion Museum at Ottawa!
352. B A L D EAGLE— H a l i a e t u s leucocephalus ( Linn.).
Major Bendire has made no reference to the few specimens
of eggs collected in the Mackenzie River District many
years ago, nor to the several nests secured by us on the
Lockhart and Anderson rivers. They were built on high
trees close to the river banks, and were composed of dry
sticks, twigs and branches, lined with deer hair, mosses, hay,
and other soft materials. There were two or three eggs in
each nest. In one instance only did the parents make any
hostile demonstration when their nest was being robbed—
they generally flew away and kept at a safe distance. They
are not very numerous in the Arctic regions, while it is
doubtful if any breed to the northward of Fort Anderson.
An example bird was shot near Fort Resolution, Great Slave
Lake, in the spring of 1885, and it was afterwards forwarded
to Dr. Bell.
Major Bendire states that " incubation lasts ' about a
month, and both sexes take part in this duty. But a single
brood is raised in a season. One of the laid eggs is always
somewhat larger than the other, and occasionally this difference
in size is quite marked. The eggs are pure white in
colour, but frequently nest- stained; in very rare instances
slight traces of markings are observable, of a pale buffy-brown,
and in the handsome series of eggs of the bald eagle
in Dr. Ralph's collection aTe two such specimens. The shell
is strong, granulated, and without any lustre. The shape
varies from a rounded ovate to an ovate, the former predominating.
Eggs from the more northern breeding grounds
are considerably larger than those from Florida and the
Gulf Coast."
In his " Catalogue of Canadian Birds," Professor J.
Macoun has entered the northern bald eagle under H. leucocephalus
