The world isn’t just getting busier for humans. With global warming changing the ocean’s temperature, whales are constantly finding ways to deal with a rapidly changing environment. That means a bit of improvising on their part - you could even say it's multitasking.
Traditionally, whales sing mating songs at their warm water breeding grounds, but researchers studying 10 humpback whales have heard them already singing breeding songs in their late season feeding grounds. In a couple of cases, they even heard hour-long mating songs sung while the whales were diving for food.
In the past, it was assumed this type of song was only sung when they arrived at their breeding grounds, but because of the thinner ice in the Western Antarctic Peninsula, it’s thought that the whales are sticking around longer to feed on krill. Findings such as this are suggesting the feed-or-breed model is inaccurate description of whale behavior. More research is needed to find out just how common this type of multitasking is becoming among other whale species. Maybe we’ll even have some of our own hydrophones out there on the task.
