There should be a small door, similar to the one described for the 
sparrow trap, at one corner, through which the captured birds may 
be driven to the gathering cage.

stands on three sides, the fourth being supported in a horizontal posi- 
tion by a stick to which a “ pull string” is attached. 
In order to eliminate swaying when the string is pulled and to 
provide more rapid action, it is advisable to cut the supporting stick 
in two and fasten the pieces together with a small hinge. Have 
the hinge on the inside when the trap is set. A light pull on the 
string will drop the tray instantly.
