The mixed blessing of echolocation: differences in sonar use by fish-eating and mammal-eating killer whales
Article Abstract:
Fish-eating and mammal-eating killer whales exhibit different patterns of echolocation sounds to locate and catch their prey. Fish-eating resident whales produce sonar clicks 27 times more often than mammal-eating transient killer whales, possibly due to higher probability of warning the prey. The resident whales apply echolocation frequently during foraging while transient whales do not use echolocation frequently during travelling or foraging. Information is most likely shared as echolocation use decreases with the increasing group size of both the resident and transient whales.

The vocal behavior of mammal-eating killer whales: Communicating with costly calls
Article Abstract:
The way in which the superior hearing ability of mammalian prey has shaped the vocal behavior of the transient killer whale ecotype is determined. The results show that increase in vocal behavior after a successful attack may represent food calling, but is more likely to reflect an increase in social interactions during feeding and/or the fact that the cost for vocal behavior is comparatively low after a successful attack.

Seasonal patterns of singing in the willow warbler: Evidence against the fertility announcement hypothesis
Article Abstract:
Male birds use a range of behaviour patterns to reduce their chances of being cuckolded. Song is hypothesized to be one such paternity guard. However male willow warblers were found to sing little when females were fertile. Mate guarding and singing can be interpreted as two conflicting behaviors.
