- 105 mile Lake. July 12 + 13.
Set trap in same place as last
year then swept the lake finding
broods as follows:-
Redhead - +11 2's, + 4 2's, + 4 1's
Canvasback + 9 2's, + 4 2's
Mallard + 10 3's

Scaup + 6
12 whitewing scoter ads. [adults]
50 +/- Scaup +'s
11 Goldeneye yrl's [yearlings] + unattached [female symbol]'s.
Baldpate + yng [young] # unknown.
3 broods of 4 Holboell Grebes.
1 pr. [pair] horned grebes
Red wing + yellowheaded blackbirds abundant
Several pairs of coots.
While sexing the ducks noted that
all the yng [young] buffleheads had a small
black protuberance mid-neutrally
on the proctodeum. This could easily
lead to the identification of the
[female symbol]'s as [male symbol]'s. This was absent on ad [adult] [female symbol]'s.
The young [male symbol]'s are distinguishable,
as soon as the secondary coverts
are out, by the greater amount
of white on them.
