"It is time for her to go home," Brian Gorman said. "She's got a ticket, her bags are packed and we're just waiting for word from the Canadians."

Gorman said U.S. researchers gave results of the orca's final battery of medical tests to their Canadian counterparts over the weekend. She was found to have no communicable diseases, and an itchy skin condition and internal condition that made her breath smell like paint thinner have cleared up.

"She's behaving like a healthy, active young whale," Gorman said.

Spokeswoman Michelle McCombs with Canada's Department of Fisheries and Oceans did not immediately return a Tuesday call for comment on her agency's stance in the matter.

Gorman said Canadian researchers probably got their first look at the latest test results Tuesday, since Monday was the Canada Day holiday.

He said the NMFS and Canadian officials had been in daily discussions about options for moving the 2-year-old, 1,240-pound killer whale north. Authorities hope she will rejoin her family, or pod, when they make their annual summer visit to waters east of Vancouver Island.

She was captured by an NMFS team June 13, and has been under close watch since in a 40-by-40-foot holding pen in Clam Bay near Manchester, on the Kitsap Peninsula across Puget Sound from Seattle.

The agency decided to capture her in part because of concerns about her health, and also because she had become extremely friendly with small boats off Vashon Island - raising concerns about both her safety and that of boaters.

The whale, dubbed A-73 by researchers for her order in her birth pod, was first spotted near the Vashon ferry dock in mid-January. Researchers believe her pod left her behind after her mother died, and she found her way into Puget Sound.

Whale activists are helping raise money to cover capture and relocation costs, which could reach $500,000.

The whale has adjusted well to captivity, Gorman said. Since her first few days in the pen, when she ate only one or two 5-pound salmon, she has increased her intake to a steady 40-50 pounds of fish and significantly more some days.

Canadian officials have said they would not allow A-73 into their waters if there was any sign she could have communicable diseases. However, Gorman said the U.S. team has conducted an array of tests for diseases including the dangerous morbillivirus.

"It's a bad virus," he said. "It would have been a disqualifier. But we had run a test in May, one again after she was taken out of the Sound, and again last Tuesday, and she was negative all three times."

Canadian experts will oversee the effort to reunite A-73 with her home pod in Johnstone Strait, off the northeast coast of Vancouver Island. Plans call for her to be held in a penned-off cove to allow the her and the pod to become accustomed to each other.

Orcas, actually a kind of dolphin, are found in all the world's oceans.

The population of Washington state's three resident pods has dropped from 98 in 1995 to 78 today. NMFS considered listing the mammals for protection under the federal Endangered Species Act but said last month the pods did not qualify as a distinct subspecies. Other efforts are planned.

Orca Fund

The orca advocates have set up a fund to help pay for Springer's rescue. It's the "Orphaned Orca Fund" set up at Islanders Bank in Friday Harbor.
