Subject: Predatory behaviour observed in pygmy killer whales.

During a recent survey trip to the southern Bay of Biscay as part of an
ongoing study of cetaceans in the Bay of Biscay and Channel areas two groups
of pygmy killer whales (Feresa attenuata) were observed.  They were in close
proximity to other species with calves.  In a number of sources it is
suggested that this species is a predator on other cetacean species.
However, I have only been able to find Perryman and Foster (1980) that has
direct observation of predation and in this reference their is some debate
about the species. The only other references I have been able to find are
about captive behaviour (Pryor et al., 1965, Best 1970, and Nishiwaki et
al., 1965).  Despite the usual searches this is the best I have come up
with. Is anyone working on this species at the moment? Can anyone suggest
any other sources that may be less accessable.
