What is a block perch commonly used for?

A block perch is primarily used as a tethering point for longwings outdoors. This type of perch is designed to provide a stable, secure place for birds of prey, especially those that have longer wingspans. The structure typically elevates the bird to a height where it can survey its surroundings while being tethered, allowing for more natural behavior and reducing stress.

When longwings, such as falcons and some hawks, are trained, they benefit from being able to observe their environment from an elevated position. This setup aids in the training process by helping young birds learn to focus on their prey or respond to the trainer’s cues while still being safely secured.

In contrast, other uses mentioned in the distractor choices do not align with the main purpose of a block perch. For instance, training shortwings would typically involve different types of perches or setups suited to their unique training needs. Attracting pigeons or providing shelter against predators falls outside of the primary function of a block perch in the context of falconry.
