In the traditional survey area, several birds that gunners love to cross beads on showed gains, such as gadwall (+2%), canvasbacks (+11%), and scaup (+2%).
Flotsam gives shelter to sandflies and other food for the small flocks of wading birds that kept wheeling in like a single organism, landing or taking off on the instant in perfect unison: sandlings, ringed plover, gadwall and dunlin.
During the spring and fall migration periods, extensive use is made of the area by most waterfowl in the mid-Atlantic region, including Canada geese, greenwinged teal, bluewinged teal, gadwall, pintail, wigeon and shoveler.
Particular importance is attached to black duck, mallard, gadwall, bluewinged teal, wood duck, bobwhite quail, ringnecked pheasant, American woodcock, mourning dove and recently reintroduced turkey, because of their importance as game birds and their occurrence as nesting species in the wetlands and upland fringe.
GADWALL Population numbers are up, so toss three to five gadwall decoys — or mallard hens — in a cluster near the shore side of your decoy spread to convince "gray ducks" to pitch in.
An hour later, we were shooing gadwall and teal out of the decoys as we waited for one last bunch of mallards to fill our mixed-bag limit.
As we towed the boats along the shore, we kicked up little bunches of ducks here and there, and the low sun at our backs lit up hundreds of them-mallards, teal, gadwall-flushing at our approach, swirling like multicolored flakes in a snow globe.
Be patient: Teal and gadwall fly early, but the main event starts at midmorning when the mallards come back from the fields.
In the traditional survey area, gadwall are up 56 percent.
The hen wigeon can be confused with the hen gadwall, but the latter's bill is orange-red and its wing lacks the green stripe separating the speculum from the shoulder patch.
