SOUTH KINGSTOWN, R.I. — Maybe 10 times a week, someone calls Steve Lazicki looking to get rid of a parrot.

They’re too loud, too demanding and sometimes just too long-lived.

Now, the shelter that Lazicki calls his orphanage may have to close its doors.

The commercial building where Lazicki runs his Birdhouse and Rescue is slated for demolition. He and the 80 avian strays in his care must be out by Dec. 30.

With affordable space hard to come by, it isn’t easy to find enough room to accommodate dozens of the large, loud bird. Raising his voice over the squawks and squeaks of the macaws, parrots and cockatoos, Lazicki said he worries about his flock’s future.

“They’re my kids,” said Lazicki, 67, an Army veteran and former aerospace machinist who has run the shelter for 17 years. “They’re very intelligent. They need a lot of attention. People often buy a parrot without any idea of what they’re getting into.”

The shelter takes in abused and abandoned parrots and works to find them new homes. More than 50 of the birds have been adopted so far this year, but there’s a steady stream of parrots, macaws and cockatiels right behind them.

Birds are America’s third most popular pet, after cats and dogs. Parrot popularity began to soar a few decades ago. The 1970s television show “Baretta,” whose title character had a cockatoo, is cited as one reason for the surge in popularity. While it’s now illegal to import most parrots into the U.S., breeders have stepped in to supply the market.

Many owners, however, aren’t prepared for the challenges and decades-long commitment of caring for parrots and their relatives. With the intellect approaching that of a human toddler and a lifespan much longer than a dog or cat, parrots demand years of intellectual and social stimulation. They’re loud, sometimes aggressive and many species can outlive their owners.

“They were a fad pet and millions were sold for years, and now the problem is coming home to roost,” said Marc Johnson, founder and CEO of Foster Parrots, an organization that operates New England’s largest parrot sanctuary out of a former chicken farm in Hopkinton, R.I.

The sanctuary houses about 450 parrots, and adopts out about 80-100 birds each year. Johnson said his organization is forced to turn away nearly 1,000 people a year looking to relinquish a parrot. He said his sanctuary doesn’t have room to take in Lazicki’s birds.

Lazicki arrives at the South Kingstown shelter at 5 a.m. most days to begin the routine of feeding the birds, cleaning the dozens of cages and “socializing” with the talkative birds. He also fields calls from people looking to adopt parrots. Some are approved for adoption, but many are not. Lazicki recalled a person who called the shelter asking to adopt four parrots. When Lazicki pressed them, they said they wanted the birds as props for a luau-themed party.

The shelter is funded through donations, adoption fees and Lazicki’s Social Security checks. It can cost more than $1,000 a month just to feed the birds.

Parrot rescue shelters like Lazicki’s around the nation face the same challenges, according to Denise Kelly, a board member at the Avian Welfare Coalition, a group that advocates for the humane treatment of parrots. Kelly said that while some people have legitimate reasons for giving up a pet bird – old age, a move overseas – many are abandoned because the owner didn’t appreciate the challenges of caring for the bird.

“These animals are very different from a cat or a dog,” she said. “People see the dancing, entertaining, talking bird on TV and they think that’s what they’re going to get. But these are wild animals.”

“When you take in a bird, you become its flock,” Lazicki said.
