BF for differences in nursing duration between the disturbance scenarios and control observations (in which no disturbance occurred).

The probability that the nursing duration in the first scenario was longer than in the second one is also shown. Scenario 1 (S1)–although nursing is momentarily interrupted by a disturbance, the mother-pup pair does not flush and continues to nurse; Scenario 2 (S2)–nursing is interrupted by a disturbance and the pair flushes, but recovers in less than 10 min and continues to nurse; and, Scenario 3 (S3)–nursing is interrupted by a disturbance, the pair flushes, and nursing does not resume until the end of the low tide cycle occurring during the sampling effort conducted on that day. The control observations (C) comprised nursing events that were not interrupted because no disturbance source was present.
