Flushed from open wet spot among tall sedges, etc. Lesser Canada Geese - at least 600 total in the area, together with a few Cackling Geese (10-15). Mallards - seemed to be well distributed over all the swamp area. At least 350 pairs, as they were mostly paired up, and about equal distribution of sexes.

Some pairs were even resting side by side with their bills tucked underwing. Green-winged Teal - perhaps 300 or so birds in a couple of main flocks. Shovellers - There was a predominance of males and lst year males, but there was a limited amount of pairing up. Perhaps 50 pairs, and 200 single birds seen.
