Bird Feeder Update

Well out of our 3 pine cone bird feeders, this is the only one left! I have no clue what drug off the other 2 but they are long gone and the weird thing is we have never seen a bird in our yard! HMMMMMMM..... I don't know if it is the time of year they are just not around or what the deal is but we never see birds in our yard. Maybe it will be different in Spring? Let's hope so!
