Abstract

Annual monitoring of Bank Swallows (Riparia riparia) along the Sacramento River, California has been conducted since 1986 to determine population trends, evaluate impacts from bank protection and flood control projects, and implement and monitor mitigation efforts. The population of Bank Swallows in a 50-mile river reach remained static over 3 breeding seasons from 1986 to 1988 despite ongoing bank protection projects. The proportion of burrows occupied by breeding swallows and the mean number of young/nest with young in a nesting colony was not significantly different between 1986 and 1988. Six experimental mitigation sites constructed in 1988 were successfully used by breeding Bank Swallows.
