A young killer whale that was trapped for more than a month in a lagoon on Vancouver Island swam past a bottleneck at high tide early Friday, reaching an inlet that could take it to the open sea, officials said.
The Ehattesaht and Nuchatlaht First Nations said in a statement that a team monitoring the 2-year-old calf saw it swim past the area where its mother had died, pass under a bridge and head down the inlet “all on her own.”
The young orca still must leave the Little Espinosa Inlet to reach open ocean, The Associated Press reported.
The calf had been stuck in the tidal lagoon near the British Columbia village of Zeballos about 450 kilometers (280 miles) northwest of Victoria since March 23, when its pregnant mother became trapped at low tide and died on a rocky beach.
“Today the community of Zeballos and people everywhere are waking up to some incredible news and what can only be described as pride for strength this little orca has shown,” Chief Simon John said in a release.
Officials said they hoped that once the whale reaches the open sea, it calls will be heard by its orca family.
John said officials and nation members were putting protective measures in place to ensure the whale has no contact with people or boats.
“Every opportunity needs to be afforded to have her back with her family with as little human interaction as possible,” he said.
An attempt in mid-April to free the whale involved using a net to corral her into a large fabric sling in shallow waters. The whale managed to dodge a 50-person rescue team that was using boats, divers and sophisticated underwater detection equipment.

Muddy footprints left on a Kenyan lakeside suggest two of our early human ancestors were nearby neighbors some 1.5 million years ago.
The footprints were left in the mud by two different species “within a matter of hours, or at most days,” said paleontologist Louise Leakey, co-author of the research published Thursday in the journal Science.
Scientists previously knew from fossil remains that these two extinct branches of the human evolutionary tree – called Homo erectus and Paranthropus boisei – lived about the same time in the Turkana Basin.
But dating fossils is not exact. “It’s plus or minus a few thousand years,” said paleontologist William Harcourt-Smith of Lehman College and the American Museum of Natural History in New York, who was not involved in the study.
Yet with fossil footprints, “there’s an actual moment in time preserved,” he said. “It’s an amazing discovery.”
The tracks of fossil footprints were uncovered in 2021 in what is today Koobi Fora, Kenya, said Leaky, who is based at New York's Stony Brook University.
Whether the two individuals passed by the eastern side of Lake Turkana at the same time – or a day or two apart – they likely knew of each other’s existence, said study co-author Kevin Hatala, a paleoanthropologist at Chatham University in Pittsburgh.
“They probably saw each other, probably knew each other was there and probably influenced each other in some way,” The Associated Press quoted him as saying.
Scientists were able to distinguish between the two species because of the shape of the footprints, which holds clues to the anatomy of the foot and how it’s being used.
H. erectus appeared to be walking similar to how modern humans walk – striking the ground heel first, then rolling weight over the ball of the foot and toes and pushing off again.
The other species, which was also walking upright, was moving “in a different way from anything else we’ve seen before, anywhere else,” said co-author Erin Marie Williams-Hatala, a human evolutionary anatomist at Chatham.
Among other details, the footprints suggest more mobility in their big toe, compared to H. erectus or modern humans, said Hatala.
Our common primate ancestors probably had hands and feet adapted for grasping branches, but over time the feet of human ancestors evolved to enable walking upright, researchers say.
The new study adds to a growing body of research that implies this transformation to bipedalism – walking on two feet — didn’t happen at a single moment, in a single way.
Rather, there may have been a variety of ways that early humans learned to walk, run, stumble and slide on prehistoric muddy slopes.
“It turns out, there are different gait mechanics – different ways of being bipedal,” said Harcourt-Smith.
