Rare chicks rescued in Manitoba catch flight to Ontario before flying south

In mid-September, after two weeks of rehabilitation and flight training with other young chimney swifts, the chicks were successfully released into a flock of 500 adult swifts in the chimneys of a brewery in London, Ont.

“The standing joke is that I cry at every release. It is a fascinating, fascinating process,” said Debbie Lefebre of Swift Care Ontario, which cared for the birds in London.

“Most birds you can release where there’s good food. These have to released where there’s a sizable flock of birds.”

Parks Canada staff who discovered the chicks reached out to the Prairie Wildlife Rehabilitation Centre in Winnipeg, and with some help from provincial workers and others, the best option for joining a flock was determined to be in Ontario.

The birds travelled there on a commercial airline.

Lefebre, who is a retired school principal, said chimney swifts are “incredibly high maintenance” because they need feeding every hour from six in the morning until nine at night. Since they’re aerial feeders, even adult birds in captivity need to be hand fed.

They also need special cages because they roost vertically, like bats except with their heads up instead of down. And for the four fledgling Manitoba birds that hadn’t yet learned to fly, Lefebre said they had to be taught how to fly into a chimney.

That required an artificial chimney — which was actually a cardboard box that was lined so they could perch on it. Lefebre said the birds were lured there with crickets and worms, and once one started feeding, it made a lot of noise that attracted the others.

She said she already had a few other chimney swifts, including one that was the same age as the Manitoba birds. Their peer had already gotten the knack, so the Manitoba birds were able to learn from it.

But the season was getting late. Chimney swifts were converging in London, preparing for their annual migration. Lefebre was investigating the possibility she might have to drive the young birds further south to Windsor, Ont., where they could unite with another flock that was also gathering, in case the London flock took off.

But the weather stayed warm and the birds hung around until the Manitoba birds were finally ready for release.

Lefebre said she waited until some of the flock were visible overhead and the young, captive birds could hear them. She unzipped the mesh cage and the birds flew straight up.

“Wild birds immediately fly down and start to circle with them. I call them ‘the welcome wagon.’ That happens at every single release, that they will hear the babies chittering and they’ll come and sort of incorporate them into the flock,” Lefebre explained.

“They’ll fly around for maybe an hour and then they follow the flock into the chimney, which is a completely new chimney for them, but they follow the flock.”
