During the colder, months, fresh unfrozen water is just as important. A source of water can dramatically increase the number of bluebirds you attract in your backyard. There are many ways to offer water including birdbaths, drippers, misters, shallow dishes and small ponds. You can offer ground level birdbaths, pedestal birdbaths or hanging birdbaths. It is important to consider the area where the bath will go.
Bluebirds like to have perches nearby to preen afterward.
Situate your birdbath near a fence post, tree or shrub that offer lots of perching space. Look for a basin that can be easily cleaned and has a gentle slope so bluebirds can wade into the water. Anything deeper, and bluebirds will avoid it. To accommodate more than one bird at a time, the diameter should be at least two feet. Make sure the bottom surface is rough to allow for solid footing, or place small rocks in the bottom to create different depth levels for bluebirds to perch on.
