I'm getting ready to take the feeder in as well.
However,
this morning I saw a woodpecker behaving very strangely. It was flying in it's normal up and down motion but when it finished checking at a tree it would take a 90 degree dive to-wards the ground than up again to another tree. Then it would do it again. I have never seen this behavior before. I took out the bioc. and could not identify the specie. I know my Downey,Red Heads, Pileated, and Hairy, but this one was totally gray/blackish. Then it took off. I am stumped.
