A question regarding the difference in behavior in the winter of 'my'
goldfinches: I live in the Methow Valley in eastern WA, and have
goldfinches feeding regularly, and heavily, at my feeder (black sunflower
seeds) for the warmer 8 months of the year. However, in the winter they
seldom to rarely come by, and when they do they only feed lightly; also,
they are much more skittish than they are the rest of the year. I know that
they are regularly around in the winter, since I hear them frequently. Can
anyone tell me why they don't want my sunflowers in the winter, when they
most decidedly do the rest of the year?

Thanks,

Birch Berman
