154 THE CONDOR Vol. XXIII 
cept one young which consorted with Semipalmated Plovers), Baird, Least, 
Western, and Semipalmated Sandpipers (all juveniles), Turnstones (juveniles) 
and one each of Northern Phalarope, Pacific Golden Plover, and Lesser Yellow- 
legs, the latter taken to ensure identity, a bird of the year. Two more Lesser 
Yellow-legs and the first Wilson Snipe were seen on the 28th; and the month 
closed with the influx of large flocks of juvenile Sanderlings which kept sepa- 
rate from the adults, and the presence of nearly all the species seen during the 
month in fair numbers, except Golden and Black-bellied Plovers and Lesser 
Yellowlegs which were not seen again. The resident Spotted Sandpipers and 
Semipalmated Plovers were in reduced numbers; the adults of both had all or 
mostly left. 
I left the Queen Charlotte Islands on the 4th of September and except for 
a few Wandering Tattlers and enormous numbers of Northern Phalaropes saw 
no waders among the islands nearer the coast where I spent the next few 
weeks. Towards the end of September I arrived at my home on Okanagan 
Lake in the southern interior of British Columbia. Usually, although the cli- 
mate is mild, all the shorebirds have left by this time except a few Black-bellied 
and Killdeer Plovers, Greater Yellowlegs, and Pectoral and Spotted Sandpip- 
ers. This season must have been a very remarkable one, however, as on the 
25th of September I saw eight species on one small alkaline pond in the foot- 
hills—one Black-bellied Plover, five Killdeers, six Pectoral, one Least, one 
Baird and one Stilt Sandpiper, and one Long-billed Dowitcher. The Stilt 
Sandpiper was taken, a young bird changing to winter plumage. Surprising 
as this collection was for so late a date, it was nothing compared to what I saw 
about a month later in the Province of Alberta. 
I arrived at my duck-shooting grounds there on the 9th, and although the 
nights were cold with quite thick ice on the smaller ponds there were numbers 
of Black-bellied and Killdeer Plovers and Greater Yellowlegs still remaining. 
On October 21st, when duck-shooting at Beaver Hills lake, 45 miles east of Ed- 
monton, I was astonished at the number of small shorebirds. There had been 
very heavy frosts, at least 17°, and all the ponds were frozen, with a good deal 
of ice along the edges of the lake; yet the following waders were positively 
identified: Black-bellied Plover (common), Semipalmated Plover (1), Sander- 
ling (3), Baird Sandpiper (3), Pectoral Sandpiper (5), Stilt Sandpiper (1 in 
full winter plumage taken, a young bird), Dowitcher (Long-billed? 3), Wilson 
Snipe (common)—eight species in winter conditions in latitude 54°. I saw a 
Greater Yellowlegs on the 24th flying over an icebound lake. This brought my 
observations on the fall migration to a close for 1920. 
The north end of Graham Island, where ‘most of my work was done, while 
offering every attraction to shoebitedls, is evidently not one of their stopping 
places, although the large migration seen on July 3 proved that it was directly 
in the way of their flight-line. The large number of Peale Falcons breeding 
along the coast here may have something to do with this. Falcons are invet- 
erate hunters of shorebirds, and here they breed in greater numbers than in 
any part of the world, I should think. At the height of the shorebird migra- 
tion, the end of July, I spent about a week on Langara Island, at the extreme 
north end of the Queen Charlotte group. Every rocky point held the aerie of 
a pair of falcons, and sometimes the yelping of three different broods of young 
birds could be heard from one stand. The rocky reefs should have been covered 
with Turnstones and Surfbirds yet not a single one was seen; nor were there
