It's that time of year to get outside and take note of our fine feathered friends.
The 21st annual Great Backyard Bird Count is being held across North America this weekend.
Bird watchers count the birds they see for at least 15 minutes and submit their checklists online.
Bird Studies Canada spokesperson Kerri Wilcox says the data is useful in their research.
"We can get a real handle on trends in bird populations. And this alerts scientists to problems with a population species or it tells us which species are doing well."
Wilcox says the event gets Canadians outside and can be quite social.
"It's great fun to do in a group. And it's a great way to get kids involved and get them excited about watching birds. And if people watch birds and are excited about that, then they'll care about the environment."
According to Wilcox, almost 15,000 checklists were submitted last year from across the country.
She says there's no need to pre-register.
