I now see more clearly the fearsome predator that is the Chestnut-backed Chickadee. His terrifying manner connects him all the way from falcons recently to eagles earlier, and -- much earlier -- to Tyrannosaurus rex. His terror is subtler than that of T. rex, with a multitude of insects taking on the role of cowering prey once played by Stegosaurus.
Chestnut-backed Chickadees, like all songbirds, have a long evolutionary history linked to apex predators like hawks, and later, falcons. Photo by Steve Zack ©WCS.
