Yesterday, the Bluebird family returned, and this time the youngsters checked out both nestboxes. They seemed particularly interested in the twoholer, coming several times to explore. I thought it was neat to see them using the two holes so effortlessly. And of course it was hilarious to watch the little sibling rivalries going on. They very much reminded me of me and my sisters. They are not nesting right now, they are kind of scouting the area and also practise for spring.
