What is the requirement for California native captive bred raptors when released into the wild?

When releasing California native captive-bred raptors into the wild, the requirement is to equip them with one transmitter. This measure is essential for tracking the health and behavior of the raptors post-release, helping to monitor their adaptation to the wild environment. The use of a transmitter allows biologists and wildlife managers to collect important data on the birds' movements, breeding success, and overall survival, which can inform future conservation efforts and management strategies.

In contrast to the other choices, the absence of requirements (none) does not ensure the necessary tracking and management needed for assessing the reintroduction success of the species. The option of two transmitters may seem plausible for redundancy, but the established protocol only mandates one for effective monitoring. A health certificate, while an important aspect of the general health and welfare of raptors prior to release, is not a specific requirement for monitoring their movements post-release. Therefore, the requirement of one transmitter stands out as crucial for the effective conservation and study of these birds once they are reintroduced into their natural habitat.
