Hi John (et al),

These are handy tips about woodpecker drumming, since I always end up =
noting heard drums as woodpecker sp, unless it's the especially =
distinctive drum of a sapsucker.

There's more tips, with sounds and spectrograms for comparison, here. =
The only one of our regular woodpeckers that's missing is Black-backed, =
whose drum taps speed up (less dramatically than the sapsucker's slow =
down) and can be heard here.

Cheers,
Andy

often about 10 seconds apart or less. There can be an overlap in these =
time measurements between Downy and Hairy but they appear to be hold up =
when averaged over a few minutes of listening.
