We report a likely unsuccessful parturition of a southern right whale at
Península Valdés, Argentina. Observations were made during a whale watch
trip. During labor, the calf’s tailstock emerged from its mother, but later
most of its body returned back inside. The calf did not move and the
mother´s behavior could be described as unusual. The cow was later seen
alone and then, in a mating group. We presume her calf was born dead or died
shortly after birth. This is the first known observation of an apparent
unsuccessful birth in a mysticete species in the wild.
