A swallow exclusion plan was developed to exclude cliff swallows (Petrochelidon pyrrhonota) from nesting under the Coffee Road Bridge in Bakersfield, CA, during the construction of the River Canal Backup Weir Project. Plywood and high-density polyethylene plastic curtains were installed along both spans of the bridge prior to the start of the nesting season (February 1). The combination of angled plywood and the plastic curtain was designed to make nesting surfaces less appealing and obstruct entry points. Weekly inspections were conducted to verify the continued integrity of the swallow exclusion and to document swallow nesting behavior. The exclusion materials remained intact for the duration of the nesting season and no swallow were nesting under the bridge. Once the swallow exclusion was removed, the old swallow nests on the bridge were intact and in good condition. Additional site visits will be conducted during the 2026 nesting season to verify continued nesting at the bridge now that the exclusion devices have been removed.
