When J got home last night, we checked on the robins. Only 1 was left in the nest. He was convinced they had fallen out or been eaten, so I took a look around. No signs of birds in distress or foul play, so we figured they had flown away.
This morning the nest was empty. The last of the babies took off. We now have an empty nest on our railing.
J wants to give future generations a nice place to hang out, so we're thinking we'll nail the bird feeder to a nearby tree. He's so clever.
