Use of data on avian demographics and site persistence during overwintering to assess quality of restored riparian habitat.

摘要: Monitoring responses by birds to restoration of riparian vegetation is relatively cost-effective, but in most assessments species-specific abundances, not demography, are monitored. Data on collected during the nonbreeding season particularly lacking. We captured mist nets and resighted banded estimate species richness diversity, abundance, demographic indexes, site-level persistence permanent-resident overwintering migrants remnant restored sites California. Species remnants was significantly higher than because abundances uncommon permanent residents were greater remnants. did differ between sites. Responses among (but residents) differed.
