Active orcas spotted during whale watching trip in Monterey Bay on Saturday

MONTEREY BAY, Calif. (KION-TV) -- A KION viewer sent in video of orcas they spotted while on a whale watching trip in Monterey Bay Saturday.

In the video, according to marine biologist, owner and captain of Monterey Bay Whale Watch Nancy Black, there are two matrilines (adult females with their offspring) by the names of CA140B (aka "Louise") as well as CA216B (aka "Jagged").

According to the person filming, Evan Brodsky, these orcas had just finished feeding on sea lions earlier that day. "They were spyhopping, breaching, pec-and-tail slapping and just very social and surface active!" Brodsky told KION. "The youngsters were chasing each other and the group were rolling together with lots of touching."

Brodsky added that some of the most interesting orca behavior to witness involved them chasing seabirds called murres "who can't fly easily! They were following and chasing just below [the] surface as birds flapped away on water," Brodsky added. "They grabbed a few and spyhopped with the bird in their mouth and took [it] under. Several whales did this!"

According to Brodsky, this behavior helps the orcas with their "target practice" for future hunting, although the whales do not actually eat the birds.

The crew on board Monterey Bay Whale Watch enjoyed this activity for hours, Brodsky told KION.
