Here we have Goldfinch, Pine Siskins and two flavours of Redpoll which give
some form of the wheee call. Although there are differences with one
version (not all) of the Pine Siskin being a very harsh long drawn out
zreeeeeee is distinctive but some get close to that of the Redpolls.
Probably the easiest way to tell people to differentiate these guys is by
their flight calls. The Goldfinch says "potato chip" The both redpolls
gives four little notes on one pitch ti ti ti ti and the Pine Siskin goes
Tee Tuh Tuh Tuh Tee. I have not picked up any difference so far in the
Redpoll calls.
At least that seems to work well for my students.

Subject: Re: [Nature Recordists] Bird ID Wanted
Hi Martyn (& others)
I posted a very brief sample of the hermit thrush and siskin calls on the
group site http://groups.yahoo.com/group/naturerecordists/files/
Not sure whether you can copy these to your contact who was wondering about
call id, but it might help solve one of the mysteries.
I get this sort of thing a lot....description of a bird or a sound and
someone trying to relay it to determine an ID....I'm the first to admit that
I'm terrible at interpreting someone else's description...it never seems to
be quite the way I'd describe it!
