Fig. 4

Godwit flight in relation to wind flow during an initial bout of migratory flight, aggregated by ~ 10° latitude. a Flight tracks depicted as lines extending from departure sites on Chiloé Island, Chile to arrival on the northern coast of the Gulf of Mexico. b Godwit realized travel direction and speed. c Wind direction and speed. d Frequency of in-flight behaviors (supported, full drift, partial compensation, full compensation, and correcting). Behaviors denoted with (+) occurred more often than expected and (−) occurred less often than expected via χ² test. For circular plots, directions are depicted in bins of 22.5° for visualization, with bar length proportional to the frequency of observations and bar color representative of speed
