As a kid in Scotland, I grew up reading The Sunday Post. Admittedly I was more interested in The Broons and Oor Wullie originally, but it was still a regular feature of my weekends.
So I was pretty excited to feature in it last week! The two-page article focused on a scientific paper published by myself, Phil, and two collaborators in Australia, which focused on foraging behaviour of pygmy blue whales off Timor Leste.

Despite being one of the largest animals in the ocean, we still know relatively little about where and how pygmy blue whales spend their time. For a long time, it was thought that the whales followed the same pattern as other large baleen whales – a feeding ground in the poles, a breeding ground in the tropics, and a lengthy migration between the two with no feeding en route. But it turns out pygmy blue whales don’t follow this “fast and famine” method. Instead, they need to feed fairly often so instead have ‘pit stops’ along the migration route where they can top up their energy reserves. The challenge is finding out where these crucial pit stops are located.
Our collaborator and good friend Chris Burton from Western Whale Research was undertaking work as a Marine Mammal Observer on a seismic vessel operating off Timor Leste. He collected numerous sightings of blue whales over a two year period, including evidence of feeding. Phil and I helped to analyse and write-up these data, demonstrating that whale presence was linked with areas of high productivity, near to areas with marine canyons and a flatter seabed. Such areas are likely to have high prey density. This was further supported by the fact that some individual whales were hanging around this area for a few days and engaging in steep, fluke-up dives, which suggests foraging at depth.
From this evidence, we conclude that pygmy blue whales are likely using the Timor Trough as a foraging pit stop on their migration. This makes it an area of biological importance, and we now need to consider how to best manage it in the face of human threats… but that is a whole other research study!
