What types of birds are considered under California falconry regulations?

California falconry regulations specifically pertain to raptor species, which include birds such as hawks, eagles, falcons, and owls. These regulations focus on the management and conservation of these birds because they are integral to the ecosystem and have particular needs and behaviors that are distinct from other bird species. Raptors are also the primary focus of falconry as a sport and practice, making them the central subject of legal provisions surrounding capture, training, and use.

In contrast, options that reference only specific birds, such as geese and ducks, or all bird species, do not align with the defined scope of falconry regulations. Endangered species, while protected under various laws, are not the main focus of falconry and thus do not encompass the broader category of birds considered in California's falconry practices. Therefore, the emphasis on raptors makes the choice concerning raptor species the correct answer, as they are specifically recognized and regulated under California falconry laws.
