I observed this, juvenile, Eastern Bluebird, from the previous brood, helping feed it’s younger siblings for 6 days, prior to their fledging. The first time, I witnessed this I thought, perhaps, it was a one time event, since the mealworms happened to be close by, but then saw the juvenile fly to the ground, where he plucked a spider from the grass, taking it back to feed the nestlings, inside the box. After this brood fledged, I continued to see the helper come to a mealworm feeder,I put out in the evenings, and take worms up to a large Oak Tree, where this pair, always led their young for safe keeping the first week, so he, definitely, was a good helper! I knew this behavior occurred, but I have only witnessed it once in 10 years of monitoring.
