The male Bluebird came back to the birdhouse where his mate was incubating in the nest they had built. He was carrying a worm.
He poked his head inside the entrance to offer the worm to her. She must have declined because his head came out and he proceeded to eat the worm himself.
He hung on, considering his next move.
Then he flew away to a nearby tree, stopped for a few seconds to look at the birdhouse before flying away in search of more food for her.
