One of my cigar box birdhouses managed to attract about the most useful local bird species to my yard:
The blurry photo (thanks, telephoto lens) isn’t the best, but you can see the female on the bottom has a bit of nest-building material in her beak.
Apparently, 2/3 of a bluebird’s diet consists of insects. They also hatch multiple broods per year.
I wasn’t sure if the size of this box would attract them… I’m very pleasantly surprised that I managed to make a bluebird nest. This is, of course, part of my new “make more habitat” plan for the food forest.
I need to hang more boxes!
