That is so wonderful! I didn't get pics of mine this time around, they actually just started flying around the yard the other day. I'm sure they are gone by now. I hope they come back again this year or next!
I had got a "Blue Bird" house about 4 years ago and had Blue birds move in and hatch babies that year. The next nothing not a bird, so I went and checked the bird house and the Honey bees had taken it over.
