nest on Lake Muskoka, Ont., regularly. Mr. Tavernier took a set 
of four eggs from the nest on 24th May, 1898 ; it formerly bred on 
the Bruce Peninsula. (/. H. Fleming.) On 15th April, 1894, saw 
a pair that were breeding in a hole in the high“ cut bank ” of the 
Saskatchewan at Medicine Hat, Assa. (Spreadborough.) 
This falcon constructs no nest whatever so faras I know. It 
lays its eggs on the most inaccessible ledge of a river cliff 
of earth or rock. Four is the usual number, and in some 
instances the eggs were larger than in others. All of the dis- 
covered nests were found in the country to the southward of the 
post, and it is doubtful if they breed much beyond Lat. 68° north. 
Early in August, for several successive years, young birds of the 
season, fully fledged, but still attended by their parents, were 
noticed alon: the limestone and sandstone banks of the Mackenzie 
River. ((Macfarlane.) 
This bird breeds rarely in eastern Ontario. I saw it in April, 
1899, and the following year. A nest containing four eggs was 
taken near the Blue Mountain, Leeds Co., Ont., by Mr. W. G. 
Shelbourne. I visited the locality on the 23rd April, 1901, and 
saw the birds but they had not yet laid their eggs. The nest was 
secured later, on the gth May, and it and the eggs are now ina 
private collection in Kingston. The nest has also very recently 
been found in the Muskoka Lake district, and when in Toronto 
I saw the eggs from there. (Rev. C.J. Young.) 
I have eight clutches of eggs of this bird, taken in Muskoka and 
northern Alberta. One set of 4 eggs was collected by P. A. Taver- 
nier,at Muskoka Lake, May 22nd, 1898. The nest was on a ledge of 
a cliff overhanging the water, 25 feet from the top of the cliff and 
70 feet above the water. The nest was only a slight hollow ona 
ledge 2 feet wide, the half-devoured remains of a ruffed grouse 
and pileated woodpecker were lying on the ledge near the nest. 
Mr. Wenman has collected for me two sets of eggson the banks of 
Blindman’s River, Alberta. There was no nest in either case, the 
eggs being simply laid on the gravel. A pair nest on Scarboro 
cliffs seven miles west of Toronto and three miles from my house 
but the nest is inacessible. (W. Raine.)
