A few weeks ago I went birding with friend Roberta, who monitors quite a few Eastern Bluebird boxes in town. She has a family at her home, too. She told me about some behavior where it appeared the male was slowly trying to wean the chicks to feed themselves. You can tell from this series of pics that she was right - the male led the chicks to a small plate of meal worms that Roberta had set out, but was very clearly trying to get the point across that his job was now down. This youngster was pretty tenacious, though!
