Evidence of a Lombard response in migrating humpback whales (Megaptera novaeangliae) [PDF]
The Journal of the Acoustical Society of America, 2014 The Lombard reflex is an increase in the subject's vocal levels in response to increased noise levels. This functions to maintain an adequate signal-to-noise ratio at the position of the receiver when noise levels vary. While it has been demonstrated in a small number of mammals and birds including some whales, it has not yet been shown to occur in one

Disrupting the herd: Recreational boating alters group dispersion within beluga whale herds
The Journal of Wildlife Management, EarlyView.Recreational boating in beluga habitat remains poorly documented. Using land‐based observations in the Saguenay Fjord (Quebec, Canada), we show that increasing recreational boat numbers are associated with a higher probability of changes in beluga herd dispersion, suggesting behavioral disturbance and the need to integrate recreational boating into ...

Humpback whale song on the southern ocean feeding grounds: implications for cultural transmission
, 2013 Male humpback whales produce a long, complex, and stereotyped song on low-latitude breeding grounds; they also sing while migrating to and from these locations, and occasionally in high-latitude summer feeding areas.
