Which method is considered effective for trapping large non-migratory raptor species?

The pigeon harness, also known as a noosed pigeon, is considered an effective method for trapping large non-migratory raptor species. This method involves using a live pigeon as bait, which is tethered so that it can move around but cannot escape. The raptors are attracted to the pigeon's movements and, in an attempt to catch it, they become ensnared in the noose that secures the bait. This technique effectively capitalizes on the hunting instincts of raptors, making it a reliable trapping method.

In contrast, other methods like the dig-in method typically require the trap to be camouflaged in a way that appeals to the raptor’s natural behaviors, but it may not be as effective for species that are more cautious or that have learned to avoid traps. The dho-gazza trap is often used in different contexts and may not suit the specific needs of trapping large non-migratory species. The balloon trap, while effective for some birds, may not provide the specific allure or triggering mechanism that larger, non-migratory raptors require for successful trapping. Therefore, the use of a pigeon harness provides a targeted and efficient means to capture these birds.
