Hi Mark,
Often males and females of the one species have slightly different calls,
such as with the Powerful Owl and Pheasant Coucal. You can tell the sex by
the call. Regional variation or the age of the bird can also lead to slight
differences.

Subject: recordings of bird calls
Hi
Yesterday I visited Buderroo NP early in the morning. I heard a bird call
that I then checked against the calls I had on my phone. The call exactly
matched the call of a Wonga pigeon in terms of notes sung and duration of
the call ( the call I listened to was from a cd by Dave Stewart). I noted
at the time that the call that that the recording of the pigeon seemed to
be a bit higher than the call of the bird, which seemed a bit lower. At the
time I put this down to the recording, but I wonder if I did hear the Wonga
pigeon, or another bird mimicking it? They were plenty of lyrebirds in the
area at the time, which may have also made that call. When a lyrebird
mimics another birds call, is it exactly the same, or slightly different?
Is there anyway to tell if the call you hear was made by the species that
should make it, or it's being mimicked?
