The Eastern Bluebird using a yard nest box laid the 5th egg of the pair's 3rd clutch this morning. This follows 2 successful clutches of 5 fledglings each. This makes 3 consecutive years that yard Bluebirds had 3 clutches. There is little doubt that supplemental feeding is a factor since 8 other pairs which do not have supplemental feeding are still on the 2nd clutch. It is unlikely that any of those will produce a 3rd nest.
