Natal attraction: allomaternal care and mother-infant separations in wild bottlenose dolphins

Article Abstract:

Allomaternal care was investigated in bottlenose dolphins by monitoring the mother-infant separation and patterns of association during the initial three months of rearing. Mother dolphins do not allow other female dolphins to take the infants from them in the first week of life but allowed this behavior after this period. Further, inexperienced mothers and nulliparas are more likely to take away infant dolphins from their mothers suggesting that these females are learning to care for the young.

Prey detection by bottlenose dolphins, Tursiops truncates: An experimental test of the passive listening hypothesis

Article Abstract:

A hypothesis that soniferous fish predators detect their prey by passive listening is tested by performing controlled acoustic playback experiments with free-ranging dolphins in Sarasota Bay, Florida. Results reveal that bottlenose dolphins use passive listening extensively during the search phase of the foraging process.

Surviving at sea: Ecological and behavioral predictors of calf mortality in Indian Ocean bottlenose dolphins, Tursiops sp.

Article Abstract:

The behavioral ecology of mothers and calves during the first year of life to identify variables predicting calf mortality among bottlenose dolphins is examined. The result suggests that poor calf condition, not predation, is the primary cause of calf mortality.
