Here’s a cool video from Katmai National Park in Alaska, showing a mother bear fishing at Brooks Falls. (Bears catching salmon at waterfalls is one of my favorite sights in nature.) It’s labeled “2016 08 06 01 06 29 approx 10 15 PM ADT All 3 Grazer coys go over the falls”. “Coy” is an abbreviation for “cubs of the year”—the last season’s newborns; and “Grazer” is the name of the Mama Bear.
So, all three of Grazer’s coys tumble over the falls, fortunately without harm, and you can see how concerned Grazer is about her offspring (kin selection!). I wonder how the whole litter fell into the water.
Be sure to watch the whole thing or you’ll miss the heartwarming parts.
