Movement Patterns and Stopover Ecology of Wilson's Warblers During Spring Migration on the Lower Colorado River in Southwestern Arizona

We used radio-telemetry to examine fine-scale movement patterns of Wilson's Warblers (Wilsonia pusilla) at a stopover site on the lower Colorado River during spring migration in 2005 and 2006. The overall movements of Wilson's Warblers were restricted to small, localized areas, with an ave...

description We used radio-telemetry to examine fine-scale movement patterns of Wilson's Warblers (Wilsonia pusilla) at a stopover site on the lower Colorado River during spring migration in 2005 and 2006. The overall movements of Wilson's Warblers were restricted to small, localized areas, with an average linear displacement of only 332 m. Warblers exhibited exploratory behavior characterized by fast, long-distance, directed linear movements during the first and second day after presumed arrival at the stopover site. However, exploration was limited within the overall landscape (
