We show the number of individuals tagged (N) and the number of individuals that were eventually detected departing (probable departures, n). For stopover flights, we report the number flights observed (and the percentage of N individuals making those flights) and the number of flights that occurred 24 h or more after tagging. For both stopover flights and other movements we summarize the distances moved.
