I have had this metal anti-squirrel feeder for over 10 years. It is rusting in some places - mainly where BBs hit. We do our best to keep it full year round so as to not attract birds and then leave them hungry. All year long I am fortunate to see all types of birds. My favorite remains the cardinal in winter. There is just something so bright and cheery about the crimson plumage against a dreary winter sky.
