Grouse without a care
A spruce grouse struts confidently before me, seemingly without a care. I have often been startled when one suddenly takes flight, as the sound of its wings is quite loud. After briefly flying through the trees, the grouse brings its wings together over its back, producing two sharp claps about 0.5 seconds apart. These sounds, astonishingly, are loud enough to be heard by the human ear from a staggering 150 meters away. In addition to vocalizations, there are other non-vocal sounds made by the grouse, such as soft drumming produced by territorial males (created by the beating of their wings), a tail swish, and a whoosh made by the tail feathers during flight.
