I am looking for information regarding hybridization of finches. In particular:
Cassin's Finch (Carpodacus cassinnii) and Purple Finch (Carpodacus purpureus).
We have banded hundreds of these species at our home in Leavenworth, WA and have
found several individuals that exhibit characteristics half-way between the two.
These two species are morphologically similar, but some individuals are
virtually impossible to tell apart in the hand, let alone while in the field.
Has anyone noticed this potential for hybridization before? I would be
interested in looking at banding data from others who have banded large numbers
of these finches, escpecially in Eastern Washington where we have a overlap of
these two species. Any information would be greatly appreciated. Thanks.
