A pod of orcas swam close to shore and amazed onlookers in Seattle by treating the whale watchers to the rare sight of the apex predators hunting a bird.

The pod of Bigg’s killer whales visited Elliott Bay and were seemingly on a hunt underwater just off Seattle’s maritime industrial docks. The pod exited the bay close to the West Seattle neighborhood across from downtown, where people were waiting to catch sight of them.

Kersti Muul, who runs a WhatsApp whale alert system for the Seattle area called “Salish Wildlife Watch”, recorded footage as the whales appeared just below a lookout point.

One of the whales was seen capturing a bird and taking it below water, sparking gasps from onlookers.

It was “a once-in-a-lifetime experience for West Seattle. Not only in the whales’ proximity, but also witnessing a rarely seen behavior – chasing and catching the grebe,” Muul said in a text. “My eyes darted back and forth taking in the community’s reactions and the orcas right below our feet, visible underwater.”

Bigg’s killer whales are orcas that usually prey on marine mammals such as sea lions or porpoises. They visit the waters off Seattle occasionally and both dedicated and casual whale watchers shadow them as they explore. The pod sighted on Sunday has ventured into the Seattle waters several times over the past month.

“It’s definitely a bonding experience for the community,” Muul said. “And my hope is always that these moments inspire awe and awareness of the urban wildlife in our backyards.”
