Paul et al., I believe that displaying male spruce grouse are mostly silent,
but at least in western Canada there is a display flight that ends just
before landing with what sounds like two pistol shots -- actually the wrists
("elbows") of the wings banging together. Is this also true for the eastern
spruce grouse? Females, on the other hand, are fairly vocal, and it is
their calls that are on many tapes and CDs of bird calls -- such calls of
females will attract both other females as well as males, and such taped
calls are useful for population estimates along transects.
Cheers from Jim in Wolfville

....Other birds of interest were a ruffed grouse drumming
- heard it both going and coming back. A Spruce Grouse
flew across the brook at one point just ahead of us.
Do spruce grouse drum like ruffed grouse?
