The Bird Riders

The Bird Riders (1965), directed by Rick Grosz, is a low-budget American production from the automatic renewal window (1964–1977). While films from this era do not require a renewal filing to stay under copyright, they were still subject to the mandatory notice requirement of the 1909 and 1976 Copyright Acts. Films from this specific era that failed to include a compliant copyright notice upon publication entered the public domain immediately. A search of the United States Copyright Office records (CCE) and the online catalog (cocatalog.loc.gov) reveals no registration under this title. Furthermore, the film has been widely circulated by public domain specialty distributors such as Alpha Video, Sinister Cinema, and Something Weird Video for decades. These distributors typically concentrate on titles where notice was defective or missing. The film also appears in numerous multi-film 'public domain' DVD box sets, and it has not been the subject of any known copyright enforcement or restoration by a major successor-in-interest. Because there is no record of an original registration and the film is historically treated as public domain by the collector market without legal challenge, it is classified as public domain due to lack of compliant notice/registration during the mandatory window.
