I found this 2015 video from my classroom terrarium days, teaching biology. I can almost hear her saying, “Chomp, chomp. What’re you lookin’ at?”
Shivering thermogenesis is used by moths to raise their body temperature high enough to permit flight. This allows them to fly when butterflies can’t.
Clark’s nutcrackers are important seed dispersers, as they can’t always remember where all of their stashes are buried.
Northern flickers feed on ants whenever can find a ready trove. This one’s serious.
White ibises have the advantage of a very long beak, so they don’t have to stick their heads completely into the dirt like a flicker does.
