Loss of habitat. In 1989, there was a big trapping of hundreds of foxes at Seal Beach National Wildlife Refuge. The red foxes were killed because they put a significant threat to two endangered species of birds, light-footed clapper rail and the California least tern. Even though an animal rights group had requested an injunction to prohibit ...
Numerous birds have been known to live on Hooks Island, such as the near-threatened California clapper rail. [10] In 2011, a Point Reyes Bird Observatory Conservation Science report found that approximately 14 clapper rails had been found in the Baylands, and 19 clapper rails were "known to exist" at Palo Alto Harbor and Hooks Island.

Ridgway's rail then breeds (California rail subspecies) in the San Francisco Bay from mid-March through August, with peak activity in late June. [6] During this breeding season the bird density was approximately 0.1 to 0.6 individuals per acre; outside of breeding season densities decline to 0.04 to 0.40 individuals per acre. [ 10 ]
The clapper rail was formerly treated as a subspecies of the mangrove rail (Rallus longirostris). [5] The decision to treat the clapper rail as a separate species was based on the results of a molecular phylogenetic study that was published in 2013. [8] [9] [10] A cladogram based on the 2013 genetic study is as follows: [8]

The mangrove rail was formerly considered to be conspecific with what are now the Aztec rail (R. tenuirostris), Ridgway's rail (R. obsoletus), the king rail (R. elegans), and the clapper rail (R. crepitans), and more recently as conspecific with Ridgeway's and king rails. Worldwide taxonomic systems now agree that each of the five is a separate ...
