Give Mother Nature a valentine this year by showing how much you care about birds.

Join the 18th annual Great Backyard Bird Count on Feb. 13-16 and count birds at any location for at least 15 minutes. Then, enter sightings at www.birdcount.org, and the information gathered by tens of thousands of volunteers will help track changes in bird populations on a massive scale.

The Great Backyard Bird Count is a joint project of the National Audubon Society and the Cornell Lab of Ornithology with partner Bird Studies Canada.

Birdwatchers from 135 countries participated in the 2014 count, documenting nearly 4,300 species on more than 144,000 bird checklists — that’s about 43 percent of all the bird species in the world. In addition to the U.S. and Canada, India, Australia and Mexico led the way with the greatest number of checklists submitted.

“We want people to share their love of birds with someone new to birdwatching,” said Erik Johnson, Audubon Louisiana’s director of bird conservation. “Find someone to take with you while you count birds for GBBC this year, whether that’s at a park, around the LSU Lakes or even just in your backyard.”

The Great Backyard Bird Count is a great way for people of all ages and backgrounds to connect with nature and show some love for the birds on Valentine’s Day.
