The take of wild raptors is…

The take of wild raptors is integral to the practice of the sport of falconry. And the trapping of first year birds has been proven, in numerous studies, to have zero impact on wild populations whatsoever!!

All raptorial species have a very high first year mortality rate!! It's simply a matter of survival of the fittest - you get good enough, fast enough, or you perish.

In many other jurisdictions, falconers will trap a bird in the fall, fly it throughout the fall and winter season, and then release it in the spring.
Odds are that the particular bird may not have survived that first critical winter anyway - but in the hands of a licensed falconer, it learns valuable hunting skills, while having a guaranteed meal on the days that it was unsuccessful.

Another huge benefit to expanding the access to wild birds is that apprentice falconers would be able to trap an immature red-tailed hawk in the fall for their first bird.
The trapping takes a good deal of skill and perseverance!!
And if someone does not have the drive, the skills and the perseverance to trap their own bird, they likely won't be successful as a falconer!!

This tends to 'weed out' the people that are not committed to the sport right from the beginning.
