Here is an example of a Steller's sea eagle.

Kodiak, the Steller's sea eagle that escaped Saturday morning from the National Aviary on Pittsburgh's North Shore, is unlikely to take a trip to Lake Arthur or Glade Run Lake to fish while he is on the fly.

Jim Bonner, director of the Audubon Society of Western Pennsylvania, said there are many reasons why Kodiak will likely hang around the area of the aviary, where a section of compromised netting allowed the large eagle to fly the coop.

Bonner said Steller's sea eagles, which are native to far eastern Russia, have no instinct to find a large body of water where they can sate their hunger for fish and birds.

Also, because he is a captive bird that only flies short distances inside the netting at the aviary, Kodiak doesn't have the muscles to fly the long distances his wild cousins are accustomed to.

“He's going to tire quicker than a wild bird,” Bonner said.

Eagles of Kodiak's species also do not eat every day, so his first priority is not going to be hunting and fishing, Bonner said.

“It's probably just scared and confused,” he said.

Should Kodiak get hungry, there is no reason he couldn't find fish in one of Pittsburgh's rivers or even feed on carrion.

“He's in great shape,” Bonner said. “He wasn't a rehab bird, with missing nails or poor eyesight.”

Bonner experienced a couple escapes during his days as an employee at the National Aviary.

“They stayed close,” he said.

Bonner predicted the only way Kodiak will head for the hills is if he feels harassed or overly frightened.

“It's unlikely he would make it up (to Butler County),” he said.

Kodiak, who has lived at the National Aviary for 15 years, has been spotted multiple times in the area of Pittsburgh's North Side but remains on the loose.

The aviary was closed on Sunday and Monday so teams of avian experts and volunteers could search for Kodiak.
