Quick Answer
A pendulum-based triggering system is the best for catching finches, as it allows for a smooth capture with minimal stress to the bird. This system consists of a long, thin branch or stick with a weighted end and a trigger mechanism. The trigger is set to release when the bird lands on the branch.
Designing the Pendulum
To create an effective pendulum-based triggering system for catching finches, you’ll need a sturdy branch or stick with a length of around 3-4 feet (90-120 cm). Attach a weight, such as a metal washer or a small rock, to the end of the branch, weighing around 6-8 ounces (170-225 grams). The branch should be balanced in a way that it swings smoothly when disturbed, allowing the trigger mechanism to release when the bird lands.
Setting Up the Trigger
The trigger mechanism is typically a simple spring-loaded device that releases when the branch is disturbed, such as a piece of wire attached to a small metal clip. Attach the clip to the branch near the weight, and connect it to a small loop of twine or fishing line. When the branch is disturbed, the clip releases, allowing the line to snap and catch the bird. The key is to set the trigger to release at the right moment, when the bird is in the process of landing.
Tips for Setting Up the Trap
When setting up the pendulum-based triggering system, it’s essential to place it in a location where finches are likely to visit, such as near a food source or water. Make sure to set the trigger to release at the right height, taking into account the size and behavior of the finches you’re trying to catch. Additionally, consider using a bait or lure to attract the finches to the trap, such as a juicy fruit or a small seed. By following these tips and setting up the pendulum-based triggering system correctly, you should be able to catch finches safely and humanely.
