DELTA MARSH, MANITOBA – On this huge marsh the worst weather often yields the most birds. Chased out of the far north by ice and snow, late-departing flocks of canvasbacks and bluebills arrive here in October's last days, looking to eat and rest before flying farther south, to Chesapeake Bay or the Gulf Coast.
Sometimes the weather changes so abruptly and so severely these birds arrive en masse on survival journeys. In the old days when Jimmy Robinson ran the Sports Afield duck camp on the marsh's edge, he talked about squadrons of silver-backed bull canvasbacks that emerged from snow squalls to bank over decoys in gale-force winds. In these late days of the season, ice formed near shore and whitecaps impeded hunters' travel in the predawn dark.
On Thursday morning, 40-mph winds flogged southern Manitoba, a big blow. Delta Marsh hadn't yet frozen. But its shores are impenetrably thick with bulrushes in some places, and crossing its open water in such a tempest in a duck boat would be precarious.
The day before, Wednesday, my son Trevor and I had launched our canoe in a finger of water that led to a bay the size of a small lake. Most hunters on this marsh deploy either flat-bottomed, two-ended boats or Grumman sport boats or similar. Each is rowed. But we had a canoe, and between its bow and stern in addition to Trevor and me were two dozen decoys, two shotguns, four boxes of shells and a retrieving dog, Allie.
"Let's paddle to the far end," I said.
Forty-five minutes later, we picked a point from which to scatter bluebill, canvasback, gadwall and mallard decoys.
Then we pulled the canoe into the tall rushes to hide it. As we did, our waders sank up to our shins and sometimes to our knees. Out front the decoys bobbed in the lee of the point and except for the mallards and gadwalls, which were pooled to either side, the blocks extended into the marsh in two long strings, tempting, we hoped, the bluebills and canvasbacks we had seen flying.
Though marshes lack that obvious spectacle of mountains, the two fascinate equally. This is especially true in autumn, when migrating mallards, black ducks, teal, wood ducks, gadwall, widgeon and other dabbling ducks feed on the seeds and leaves of aquatic plants, while diving ducks such as bluebills and canvasbacks prefer roots and tubers.
