Posts Tagged ‘flasher pose’

Last Tuesday I spotted a Great Blue Heron (Ardea herodias) at Occoquan Bay National Wildlife Refuge with its wings spread forward in the so-called “flasher pose.” There are several theories about why herons assume this posture. Some speculate that it is for the purpose of temperature regulation (either to warm up or to cool off) or to dry out their feathers. Others believe that it is part of the preening process and that the increased heat makes parasites more active and easier to remove.
