I am looking for a copy of:
Groth,J.G. 1993. "Evolutionary Differentiation in Morphology,
Vocalization and Allozymes among Nomadic Sibling Species in the
North American Red Crossbill Complex." _University of California
Publications in Zoology_. 127:1-143.

If someone is willing to loan me a copy or sell me a copy, I would be
ever so pleased.

I am especially interested in sonograms of the "seven types", so even
a photocopy of relevant pages would be of use.
