Improvements to the Design:


Elevator arm is now made with recycled HDPE for greater moisture resistance.

Because a large number of people wanted to use the trap for targeting starlings in addition to sparrows, I revamped the access to changing the weight setting.  It now allows full access to the counterweight, and is easily securable. Also, the hinge pin and perch "ring" have been upgraded to stainless steel to eliminate any rust.

With the original removal door size, the occasional person with large arms had difficulty reaching all the way into the trap, and those with small arms sometimes had birds escape around their arm while removing birds.  A weatherproof epdm baffle attached to the inside of the trap behind a larger (4 1/2") removal door addressed both issues.
