Bird-hunting is basically walking, or hiking, with a dog and a gun. Maybe with a pal or two.
Our Sunday hunt was not productive of meat, but we must have seen 50 Bluebirds. Whether a migrating flock or a local population, who knows? They do not migrate much, depending on food supply. Berries in winter, bugs in summer. They are a kind of thrush, like robins and lots of other birds.
The Eastern Bluebird likes large fields, meadows, pastures, beaver marshes, and golf courses. Backyards, not much. Woodlands, no.
If you scatter 5 or 10 Bluebird houses around a large meadow, they will find them sooner or later. Tree Swallows will find them too, and they can fight about it.

Pic from my pal yesterday of a male. The females are brown. Yes, they love to sit on fenceposts.
