A month ago I took photos of Pine Siskins feasting in a pine tree whose 
cones had opened. Those siskins were hanging at all kinds of angles, 
including upside down. So my guess is they would use a feeder where they 
hang upside down.

The Hosue Finches are very appreciative, but no Siskins yet. Anybody know if Siskins will use the upside-down feeders, where the bird has to hang upside down to reach the portals?
