In Georgia, the eastern bluebird’s nesting season extends from late February and early March to July and early August.  During this time, how often should bluebird nesting boxes be cleaned?

       The North American Bluebird Society suggests that boxes be cleaned after each nesting attempt regardless of whether or not it was successful.  The cleaning procedure should take place after the birds have fledged and should include removing the old nest, eggs that did not hatch, and any young that did not fledge.  This procedure removes parasites and encourages re-nesting.
