Phys.org reported on Thursday that the nighttime songs of endangered pygmy blue whales may offer a way to tell when the animals feed off Western Australia. According to the outlet, the timing of their calls could serve as a clue to their feeding activity.
The report links the whales' vocal behavior after dark to their feeding patterns in the waters off Western Australia. Phys.org presents the nighttime songs as a possible indicator that researchers could use to work out when the whales are feeding.
The finding matters because pygmy blue whales are listed as endangered, and knowing when and where they feed is basic to understanding the pressures they face. Phys.org's report frames the songs as a monitoring signal rather than a direct observation of feeding.
The summary released with the report does not name the researchers involved, the institution behind the work, or the methods used to connect the calls to feeding. It also gives no figures on how often the whales sing at night or how the songs were recorded.
What to watch next: whether the research team publishes fuller details on how nighttime calls are tied to feeding, which would show how far the approach can go as a monitoring tool for this endangered population.
