Mist Netting Trans-gulf Migrants at Coastal Stopover Sites: the Influence of Spatial and Temporal Variability on Capture Data
Year: 2004
Type: article
Abstract: We used constant effort mist netting during spring migration to sample populations of trans-Gulf migrants at two coastal study sites from 1987 to 1992. Approximately 2,500 individuals of 70 species were netted each season with approximately 5,000 net-hours of effort. Although captures per net hour and total species captured were fairly consistent each year, the seasonal patterns of capture, arrival condition, stopover duration, diversity of species, and number of individuals showed considerable variation from year to year. Differences in seasonal and annual weather patterns, the arrival condition of migrants, and habitat quality at stopover sites all influenced the probability of capturing birds with mist nets at our coastal stopover sites. Mist-net capture rates from coastal stopover sites, migratory activity indicated by radar echoes, and counts of migrants from censuses at mainland sites were correlated within a geographic radius of 100-150 km.
