There have been a number of messages recently RE: Purple Finches.
Ruth and I have noted that for the last two weeks we have the following
distribution of finches at out feeder in west Durham.
Female and young Purple Finches 45%
Male House Finches 35%
Male Purple Finches 10%
Female House Finches 10%
These numbers are not exact but are only to give an idea of the distribution.
Why so few female House Finches? I am home recovering from a version
of the flu and I watched all day and only saw 3 female house finches
while seeing 3 male Purple Finches. Is it simply that the small
flock that visits our feeder is divided this way? Or does one
see migration patterns that differ for males and females.
