Hummingbirds may need extra help surviving recent frigid temperatures

Wildlife experts say hummingbirds in B.C. may need some assistance getting food, staying warm, and tending to their nestsamidrecent snowfalls and cold temperatures.

Anna's hummingbirds, which remain in B.C. throughout the year, survive on a diet of insects and plants. When these resources become scarce in the winter, many of them rely on hummingbird feeders.

But feeders can freeze over when temperatures drop below zero.

"When we get these sudden intensely cold temperatures and snowfalls, they definitely have a much harder time staying warm and finding the food that they need," said Jackie McQuillanfrom the Wildlife Association of B.C.

The possibility of nests being covered in snow is also a concern because Anna's hummingbirds are currently in their breeding season.

The wildlife association has received several calls from people around the Lower Mainland who have seen hummingbirds struggle to accesssnow-covered nests.

"It's really important if you know that there's a nest there just to double check that it's unobstructed so the hummingbird mama can still get to the eggs to keep them warm," said McQuillan.

She says people who come across buried nests can help by carefully clearingthe snow away, ensuring not to disturb the nest. Hummingbird nests are usually found on trees or shrubs at, or below, eye level.

The rescue association has also receivedreports of hypothermic hummingbirds.

"Sometimes people will literally just find them looking like they're asleep in a snowbank," said McQuillan.

She says people across the province who come acrosshummingbirds in distress can call the association'shelpline at 604-526-7275.

People in the Lower Mainland can bring hypothermic birds to the association's facility located on the north side of Burnaby Lake.

Keeping feeders warm

Alison Moran from the Rocky Point Bird Observatory in Victoria says people shouldtake extra care to keep their feeders clean and warm throughout the winter.

"If you've made the decision to feed an animal during its breeding season, it's made a decision to breed there because of the resources you've provided," said Moran.

"Feeding them happily and then going to Mexico for a nice holiday, if there's no one around you who is also feeding them, that's not so fair."

Moran recommends people keep a second feeder that they can switch out iftheir feeder becomes frozen. She also suggests peoplemove their feeder undercover so it doesn't get covered in snow.

McQuillansays people can alternatively usea feeder heater an insulated heated covering that goes over the feeder to keep the solution inside from freezing.

Sometimes hummingbirds have gotten their tongues frozen tobird feeders that have exposed metal parts. To avoid injury, McQuillan recommends people cover any exposed metal on their feeders.
