You can really help out your bluebirds when they start feeding the nestlings by putting out mealworms at least three times a day. It is a real chore for the adult bluebirds to find suitable food for the nestlings and deliver it on a regular basis. Bluebirds recognize a “bluebird friendly” yard and will continue to visit it every year for nesting purposes.
