260 GEOLOGICAL SURVEY OF CANADA. 
(J. H. Fleming.) This bird seems to prefer holes in trees, the 
old nests of the flicker are probably the ones used. The eggs, 
five in number, are of a buff or pale yellowish brown, with 
splashes of dark brown all over, but most numerous at the 
greater end. About the first week in May, the nest maybe looked 
for in the neighbourhood of Ottawa. (G. R. White.) Breeds 
always in cavities in trees—eggs 4-6. (W. £. Saunders.) 
This species was first seen in 1892 at Indian Head, Assa., on 
16th April, and was common by the 24th. It breeds in the woods 
and in trees in the stream valleys. A nest was found in an old 
flicker’s nest in a poplar, June 5th; it contained five eggs. In April, 
1894, it began to breed on the 17th in holes in poplars. On the 
27th May, 1895, a nest was discovered in a flicker’s hole in a box 
elder tree on Old Wives’ Creek, Assa. The female sat so close 
that she had to be shoved witha stick before she would move. 
The nest contained five eggs of a deep cinnamon buff, but becom- 
ing brown or cinnamon at the larger end. This species is also 
common on Vancouver Island, always breeding in holes. It feeds 
upon mice, young birds, grasshoppers and other insects and on 
one occasion I saw one catch a small snake. I have seen nests 
from 60 to 70 feet above the ground. (Spreadborough.) It breeds 
in the interior at least as far north as Fort Rae, Great Slave Lake, 
in Lat. 62° N. (Sendire, Vol. 1., 309).
