At this time of year it is common to hear a woodpecker drumming deep in the
forest. For a few years I've been taking notes on how one might identify a
woodpecker by drumming.
Here is what I have found so far. Perhaps others have some observations they
would be willing to share.
Hairy Woodpeckers appears to be the species most often heard drumming in a
sustained way over fairly long intervals, especially in deep woods. Its drum
is about 2 seconds in length and usually well over 10 seconds apart.
The Downy Woodpecker is very similar to the Hairy Woodpecker. However I
found the drum of the Downy to be less than 2 seconds in length and 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.
The drumming of Northern Flickers is very similar to Hairy Woodpecker but
the Flicker makes so many other vocalizations between drums that it is easy
to identify.
Pileated Woodpecker is also similar to Hairy Woodpecker but has a distinct
crescendo in the drum that is easy to pick out once you know what you are
listening for.
Yellow-bellied Sapsucker can be distinguished by its slow, stuttering drum,
tapping out Morse code to another Sapsucker.
Black-backed Woodpecker, American Three-toed Woodpecker, and Red-bellied
Woodpecker I haven't yet heard drumming in Nova Scotia.
