of Alaska. It is not uncommon on the islands off the coast, 
and Turner speaks of it being taken on the Aleutian Islands. 
Nelson says that on the Siberian Coast of Behring Sea the typi- 
cal Asiatic form is common, and is of much rarer occurrence on 
the Alaskan Coast, from the peninsula of Alaska north to Point 
Barrow.

This is a rare migrant in Newfoundland, Nova Scotia, New 
Brunswick and Quebec. In Ontario it is much more common, and 
breeds in suitable localities throughout the province. Throughout 
Manitoba and the whole prairie country this bird breeds abun- 
dantly. It is also common in the Rocky Mountains and British 
Columbia, and breeds almost to the coast. Its northern limit is 
very likely the sub-arctic forest, as it seems to prefer open plains 
where brackish marshes are of frequent occurrence. 
BREEDING Nores.—This bird is to be met with in those parts 
of Ontario that are in any way adapted toits habits. Its favourite 
haunts are rough pastures with here and there a few scrubby 
bushes scattered about; if there are a few stones and gravel, so 
much the better; the birds take kindly to such spots. I meet 
with a few pairs of this species every year, and notice that they 
breed comparatively early, the full complement of four eggs 
sometimes being laid as early as the 26th of April. I have found 
a number of their eggs, and notice that for a nesting place they 
usually choose a small stoney or gravelly patch in a pasture ; 
once I found a nest among small stones and rock close to a quarry 
where the year before I had taken two nighthawk’s eggs. (Rev. 
C. J. Young.) The Killdeer Plover breeds in small numbers all 
over western Ontario. It lays four eggs, which are so placed as 
to be very difficult of discovery. (W. Saunders.) This species 
nests in the gravel at the margin of lakes and ponds, also on 
bare ground on the prairie and in ploughed fields throughout the 
whole prairie region. The nest is a hole in the gravel or ground, 
usually not far from water. Eggs, four, always standing upon the 
small end in the nest. (II. Spreadborough.)
