Orca come here to feed on herring. The Orca use communication and coordination to gather the fish into "bait balls" then swim through, stunning the herring with their tails before eating them. Creating unique feeding strategies demonstrates highly cognitive behavior and is an element of whale and dolphin culture. Secrets of the Whales, an original documentary series from @NatGeo, is streaming this Earth Day, April 22, on @DisneyPlus. In addition, my book of the same title is available on April 6 (and on pre-order now). My work on whales will also be featured in the May issue of National Geographic magazine, the Ocean Issue, available online on April 15.
