There is a lot of activity in all the holes of this birdhouse with bluebirds building nests in each compartment. I never knew they liked communal living but I guess I was wrong. I snapped this photo from my attic studio. The second pic was cropped from the first to show you the bird up close. I never get over the thrill of seeing such beautiful plumage. They really are the birds of happiness. I hope you have a happy day too.
UPDATE: I just added the third photo. Look closely and you'll see the female taking nest-building material into the hole. The male just hangs around looking beautiful or perches on top of the house acting as the lookout.
I currently use Adobe Photoshop Elements
