Saving Canada’s Hardiest Hummingbirds Requires Extreme Care

Then, every couple of hours for the rest of the day, he braves the cold to substitute the old feeders with warm reserve ones. This from a man who fled to B.C. to escape Ontario winters as a young man. I’m not sure I can swear my sister and I ever got that level of care and feeding.

Apparently, my father’s devotion to B.C.’s hardiest hummingbird species is not unusual. MARS Wildlife Rescue Centre in the Comox Valley on Vancouver Island is fielding a rash of calls from people looking to help or save their tiny charges.

“People are really, really being wonderful trying to save these birds,” says Jo Stiles, a MARS animal caregiver. “They are being really attentive with their feeders so hummingbirds can make it through this cold. But it requires a tremendous effort.”

The birds, which weigh less than five grams, need to constantly eat to maintain their body weight and energy, she adds. Since Dec. 20, the rescue center has received 14 tiny feathered patients that need extra care, Stiles says. To survive the cold, hummingbirds often go into torpor, a hibernation-like state where their body temperature may drop from 107 degrees Fahrenheit to as low as 48 degrees.

People may think the birds are dead in this state, as they can be found hanging from a perch or immobile on the ground. The best remedy is to put the hummingbird and a feeder in a covered box indoors and somewhere quiet until they warm up, Stiles says.

“Let them have some time in there, and when you see them back to being active, then they can be released,” she says. “Unless it’s late in the day, then keep them overnight with a feeder and let them go the next morning.”

Birds that don’t seem to revive within half an hour indoors should be taken to a local rescue where they can get more specialized care, she adds. “That may be an indication that it’s gotten very dehydrated or so hypoglycemic that it can’t reactivate its own system and so it may need some additional help.”

The best thing people can do for the jeweled birds during winter is to make sure they have lots of warm, clean food, but be warned: Anna’s hummingbirds are notoriously territorial about their feeders. My father has given an unmentionable nickname to one pugnacious male that sits on the line across the patio equidistant from both feeders so he can easily chase off interlopers.

The bold little birds also aren’t particularly gracious to their caregivers, either. They wait on my father each morning. The moment he cracks open the door, the iridescent green and scarlet-throated aerialists are zooming and chattering about his head as if to hurry him up. My mother can’t understand why he puts so much work in for such aggressive little birds. “I don’t like them. They’re too much like humans,” she says.

But if you start feeding hummingbirds, you have to commit because they become reliant on that food source, says the SPCA. And my father is nothing but committed. He’d never admit it, but he’s forgoing a short trip to a friend’s for New Year’s citing poor weather. But I suspect the real reason is he doesn’t trust my mother to coddle his beloved hummingbirds carefully enough.
