Anyone recall the research which concluded cormorants in"scarecrow"position are not drying their wings as widely believed?
Apparently they are generating muscle heat to compensate for the chilling effect of cold fish in their bellies.
I recall the researchers fed the birds fish of varying temperatures.
Birds fed warm fish never "dried" their wings.
It seems this research has been forgotten ,as the old myth of birds drying their wings is still widely accepted.....George H
