5. Wing-Funnel Trap (figure 5). The four traps listed above are 
best used in open fields. Where birds were coming to a feeding shelter 
the wing-funnel trap was more successful. It was based upon Ralph 
King's (unpublished) Ruffed Grouse trap, and like it was made in 
demountable panels for easy carrying. Complete buffering inside 
prevented injuries, and the bob-wire door proved a very effective 
entrance. Placed under a feeding shelter with the wings extending 
out in front, the trap kept free of snow-a distinct advantage in 
stormy weather. Sharptails only were caught, but the trap could 
probably be used for any bird using feeding shelters. 
As illustrated, this is essentially a three-entrance trap, since birds 
between the wings or between one wing and the front wall are lead 
to the entrance. A simpler one-entrance trap can be made by 
bringing the inner ends of the wings about eight inches into the 
trap and fastening tile door directly to them. The inner ends of the 
wings then replace the oblique front panels. Such an arrangement, 
however, leaves a cul-de-sac on either side of the door. 
Baiting. Ear corn and buckwheat were used as bait. Open field 
traps can be placed on flattened buckwheat shocks on which ear 
corn has been thrown. Bait should be placed well in the trap, else 
it can be reached from the outside. A small amount of grain in front 
of the entrances is helpful in leading birds into the trap. It was 
found best to trap at places where birds were already coming to feed 
on grains, as in food patches or feeding shelters. 
Traps should be left open in position for several days or weeks to 
accustom the birds to feeding near and under them. The portable 
funnel and half-wheel traps can be propped up or turned on their 
sides. The netting on the sides of the non-portable funnel trap and 
the bobs of the long-bob trap can be raised, and the ends and door 
of the wing-funnel trap left off, until trapping begins. Once the 
traps have been set, it is well to have as little feed as possible availa-

ble outside of them.
