Bird Feeders

Material A
Metal. Most bird feeders are made of metal as they are durable and are easy to manufacture as a preventative measure against squirrels and other rodents stealing the contents of the feeder.

Disposal: Metal bird feeders can be placed in your recycling bin.

Material B
Plastic. Either component, or the entire bird feeders are sometimes manufactured with hard plastics.

Disposal: These types of plastic must be placed in your garbage bin.

Best Alternative
The smart option would be to invest in a metal bird feeder as they tend to last far longer than a plastic bird feeder. It may cost a bit more, but they can ultimately be recycled whereas the plastic materials cannot be.
