Birds and mammals: nongame birds: mute swans.

The enrolled bill's placeholder fields for dates, times, and signatures were replaced with the official state authentication header (STATE OF CALIFORNIA AUTHENTICATED ELECTRONIC LEGAL MATERIAL) and the specific approval date of October 7, 2025.

The chapter number was filled in as Chapter 441, and page numbers were adjusted from 97 to 96.

Mute swans are moved from a simple list item alongside sparrows and starlings into their own sub-paragraph (a)(3)(A), giving them distinct regulatory treatment separate from the other nongame birds.

A person taking or possessing a mute swan is encouraged (not required) to report to the Department of Fish and Wildlife when they take or possess one.

The department is required to collect information about enforcement actions taken by department personnel associated with the take and possession of a mute swan.

A sunset provision makes the mute swan sub-paragraph inoperative on January 1, 2031, meaning the special treatment for mute swans will expire after approximately six years.

Minor typos corrected in the legislative counsel's digest: 'allow allow' changed to 'allow', 'mute swans swan' changed to 'mute swan', and 'same similar' changed to 'similar'.

Added passage dates (Assembly September 13, 2025; Senate September 8, 2025), signature blocks for the Chief Clerk of the Assembly and Secretary of the Senate, and a Governor's approval block at the end.

Removed line numbers, the 'AMENDED IN SENATE' header, and the original introduction date (February 18, 2025) in favor of the enrolled bill format.
