The history of flight

Did you know flight appears to have evolved separately at least four times in history: in insects, bats, birds and pterosaurs. These four groups of flying animals didn't evolve from a single, flying ancestor. Instead, they all evolved the ability to fly from separate ancestors that couldn't fly. Recent studies indicate that flight may have even developed independently in unconnected groups of bats and multiple types of dinosaurs.  

A wild turkey takes flight while wading through a flooded pasture on a farm near Elkton in rural wester Oregon on Friday, Jan 15, 2021. Recent heavy rain has saturated the area. The turkeys appeared to be feeding on insects displaced by the water.

On a sunny warm January afternoon dozens of honey bees fly outside their hive on a farm near Elkton in rural western Oregon on Saturday, Jan. 16, 2021. In most cases, honey bees remain inside their hives when the outside temperature is below 50°F or above 110°F.
