One pod showed up in January and was videotaped fatally attacking two resident bottle-nosed dolphins. They may have also killed a gray whale calf, although a body was never found. Predatory orcas have breached a gray whale safe space in Baja California. Could this spell disaster for a species already struggling for survival?
In a recent report from the Icelandic Food and Veterinary Authority (MAST), 16 salmon caught in the Mjólká river in the Westfjords were confirmed to originate from farms. Signs indicate that the salmon originate from open sea farms by Haganes, where a hole in the pen caused part of the stock to escape in August.

Volunteers from the Friends of Bowker Creek Society say uncovering caddisfly larvae in the gravel beds of the stream show the water quality has improved to a level sufficient to sustain salmon and cutthroat trout.
An unusual bird was sighted in the Yukon Flats village of Chalkyitsik recently. The raptor, uncommon to the state, has also been spotted in a few other Alaska locations. Bird biologist Jim Johnson says there’s broader evidence that the nomadic turkey vulture is expanding north.
Two distinct species of orcas feed and socialize in the waters of Puget Sound: fish-eating endangered southern resident killer whales and transient, or Bigg’s, killer whales, which feed on marine mammals and are more common. They seldom mix.
It would be an obscure sighting of the species. The closest beluga population, which lives at least 1,400 miles away in Alaska’s Cook Inlet, is endangered and covered under the Marine Mammal Protection Act.
Karen Dunmall, a biologist with Fisheries and Oceans Canada, said pink salmon normally prefer warmer waters than the Arctic has been able to provide. But with the Arctic warming at up to three times the rate of the rest of the world, its waters are becoming more approachable for newcomers like this species.
Wally, the walrus who has found fame during his travels round Europe, has been spotted in Iceland more than 900 kilometers from his last known location, He was previously seen 22 days ago in West Cork, Ireland, sparking concerns for his safety.
