we've actually seen them draggin off the suet feeders into the wooded area behind our house. i call them tree rats!!

i make peanut butter and jelly sandwiches for the birds too (i put some sunflower seeds in the middle) then put them in our suet feeders when we are out of suet..the birds really love it! they love apples too, we have an apple feeder as well.

as far as the hummingbirds, if you've seen one, im sure there are more. do you put a feeder out for them??
