Which federal regulation takes precedence over state provisions regarding the possession of raptors?

The correct choice is related to the federal regulations established in 50 CFR Part 21, which specifically governs the management and protection of migratory birds, including raptors. This regulation outlines the conditions under which individuals may possess, transport, and take raptors for falconry and other purposes.

Federal regulations, such as those found in 50 CFR Part 21, have precedence over state laws due to the Supremacy Clause of the U.S. Constitution. This principle states that federal law takes priority when there is a conflict between state and federal legislation. Consequently, while states like Texas may have their own laws concerning wildlife and raptor possession, they cannot supersede the regulations set forth at the federal level.

In the context of this question, state provisions or local laws cannot permit activities that are restricted by federal legislation. Therefore, anyone interested in falconry in Texas must comply with 50 CFR Part 21, ensuring they adhere to federal standards regarding the handling and possession of raptors.
