An explanation - male agressiveness

Trail Wood #94 Earl Plato

Edwin Teale shared his observations.
“ In recent days we have caught a low-pitched, reverberating sound, accelerating in tempo, rising to a muffled drumfire at the end-the sound of a cock ruffed grouse on some log in the woods drumming with its wings to attract a mate. It is a sound that can be heard a half a mile away. For the ruffed grouse … it sends forth the invitation … in this mating season of spring.
At this time of the year the male grouse is especially belligerent. … It is this combativeness in this season of the year that appears to provide the most probable explanation for the puzzling confrontation we have observed.”
Grouse versus crow.
