Here is a male. He stays high in the trees unless he finds a sunflower seedhead worthy of hanging around for lunch.

This female made herself at home on my new "old" screen window birdfeeder. She stayed eating for 3 days but I never spotted the mail dropping in for food.
I bought a sock you hang with niger seed that supposedly finches are crazy about. Haven't seen either one since.
Date: February 2011
Location: My backyard
Behavior: She was very hungry which made her less intimidated by other birds at feeder but male was very shy and never came to feeder while I was watching. He was not far away though because I could hear his "swingset" call.
