I keep track as reports come to me, but since I am not in the immediate area I can't observe and monitor what's going on. But you're right -- many of the reports are of caniceps, and I'm sure there are not barriers to cross-mating. In fact, given the low population densities (relative to theJulie Craveshttps://www.blogger.com/profile/12006765203165236634noreply@blogger.comtag:blogger.com,1999:blog-5483269154778175081.post-71883014034601023982012-11-13T05:43:50.749-05:002012-11-13T05:43:50.749-05:00I have read that the US populaton is a result of a...I have read that the US populaton is a result of a number of subspecies ut mainly of Carduelis group and some Caniceps. Has there been any cases of interbreeding between the two groups in your reports. Caniceps would probably find local conditions similar to its original range with same extreme of temperatures. Though Carduelis is very adaptive as I found in Australia.Rod Harrisonhttps://www.blogger.com/profile/00170932535778658559noreply@blogger.com
