Foraging area consistency in Socotra cormorants. (a) Example of three tracks of birds which left the colony within the same 4‐hr interval (white star: Siniya colony; circles: dives). Birds 27 and 31 departed to sea 3.5 hr after bird 29. (b) Short‐term foraging area consistency expressed as the distance between the barycenter of dive positions in relation to the difference in the time of departure from land between trips of birds which left the colony within 4 hr of one another (black circles, y = 6.17 × (1 − 0.18^x), R ² = .20, P = .016, n = 28) and frequency distribution of trip time differences (gray vertical bars, n = 28). (c) Long‐term foraging area consistency expressed as the distance between the barycenter of dive positions of successive trips on the same day (day 1) or on days 2–4 relative to the first trip of day 1 (n = 405 distance combinations from 18 birds). P‐values indicate statistical differences between days 2, 3, or 4 relative to the first trip of day 1 (***P < .001)
