Ottawa's Wild Bird Care Centre said donors have given the animal shelter 600 incandescent light bulbs in the last two days — or enough light bulbs for the animal shelter to provide warmth for injured and recovering birds for more than 15 years.

Last week the bird care centre put the call out for the 100-watt incandescent bulbs, which use more power but are also warmer and serve an important role inside incubators.

The federal government banned manufacturers from supplying the bulbs to Canada beginning this year on Jan. 1, as part of rules aimed at improving efficiency.

In a post Monday on their Facebook page, the bird care centre said people who still had light bulbs to drop off were welcome to do so, but said they did not want people to make additional light bulb purchases on their behalf.

In an email, a Department of Natural Resources spokesperson said Tuesday there are also exceptions to the bulb ban to allow for some appliance, industrial and agricultural bulbs to stay on shelves and that they could be used to heat the incubators.

The centre is located on Moodie Drive in the city’s west end.
