Under what condition can a wild caught falconry raptor be transferred for propagation purposes?

Transferring a wild-caught falconry raptor for propagation purposes typically requires that the bird has been used in falconry for a specified period. This is to ensure that the bird is properly acclimated and has the necessary training and experience before being used in a breeding program. The rationale behind this condition is to ensure that the bird can be managed effectively in a controlled setting for breeding and that its welfare is prioritized.

This requirement also helps in maintaining the quality of raptors being bred in captivity, as it allows for the selection of birds that have shown a degree of adaptability and reliability in falconry situations. The other options do not align with regulatory practices, as training, maturity, or arbitrary timing without consideration of the bird's experience and condition would not serve the purpose of effective wildlife management and ethical falconry practices.
