abundant during the summer in some portions of the mainland 
interior. The young have been taken on Vancouver Island. 
Brooks says that a swan, (apparently this species) winters in suit- 
able localities in the Okanagan district, B.C. 
BREEDING Notes.—This species builds on the ground and the 
nest usually contains five eggs; several were also found on the 
coast and islands of Liverpool and Franklin bays in the Arctic 
Ocean. (Macfarlane.) The birds arrive on the coast singly or in 
small parties, and directly after scatter to their summer haunts. 
At Nulato, Dall found them laving their eggs by May 2!st, but 
on the sea-coast, May 30th 1s the earliest date I have of their eggs 
being taken. Dall states that they lay two eggs, but this must 
refer to a single nest, for the ordinary number is from three to 
six. The nest is usually upona small island in some secluded 
lakelet, or on a rounded bank close to the border of a pond. 
The eggs are deposited in a depression made in a heap of rubbish 
gathered by the birds from the immediate vicinity of the nest, 
and is composed of grass, moss, and dead leaves, forming a 
bulky affair in many cases. On June 14th, 1880, a swan was seen 
flying from the side of a small pond on the marsh near St. Michael, 
and a close search finally revealed the nest. The eggs were com- 
pletely hidden in loose moss, which covered the ground about 
the spot, and in which the bird had made a depression by pluck- 
ing the moss and arranging it for that purpose. The site was so 
artfully chosen and prepared that I passed the spot in my search, 
and one of my native hunters coming close behind, called me 
back, and thrusting his stick into the moss exposed the eggs.

Olor buccinator (R1cH.) WAGLER. 1832. 
Stragglers are occasionally seen on the north side of Lake Erie 
and doubtless on Lake Ontario, but by many observers this species 
is referred to the more common Whistling Swan. 
Occasionally seen passing over Manitoba, flying high in the 
spring. More plentiful inthe autumn. Only a few specimens 
noted by Spreadborough at Indian Head, Assa., in the middle of
