House Sparrows drove this bluebird from nestboxes, and she built a nest in the rafters of a covered deck.The depth of the rafter area is about 8". Photo by Bill Ebert of Leesburg, VA.

Keith Kridler notes that on the island of Bermuda, Eastern Bluebirds were originally found using old Robin nests as a base for their nests in open branches of trees and bushes. There are occasional reports of them nesting in hanging baskets (although these are often Robin nests), Topsy Turvy Tomato plant containers, old cliff/barn swallow nests, ledges of porches, and metal pipes when nestboxes or cavities are not available. See photos of a nest in a clay pot at the same location.

Chickadee nesting in stop sign. Keith Kridler photo.
 

Carolina Chickadees are nesting in the 2" inside diameter steel pipe that this street sign is mounted on. Their nest started above the second bolt (26.5" down) and the top is 13.5" down from the opening at the top of the pipe. They have to squeeze by a 5/16" diameter bolt that holds the sign to the pipe.

Chickadees have also been known to nest in rotted wooden fence posts and open stumps.

Carolina Wren nesting in bathroom. Photo by Karen Ouimet.   Karen Ouimet of CT left her bathroom window open one day... and came home to a Carolina Wren nest in a container used to hold her hair scrunchies (on the top of the wooden cabinet.) She is leaving the window open for them. It is the only bathroom in the house, but they don't seem to mind her showering, flushing the toilet, or even blow drying her hair three feet away.

Nest in breaker box.  Photo by Keith Kridler.
 

Bluebird n ests inside electrical Square D breaker panels. Each of the open doors had at least one breaker missing, creating a large nestbox. Three that were open to the weather had nests. One was an old Starling nest. The other two were probably old bluebird nests. Photo by Keith Kridler of TX.

Two bluebird pairs raised young in 55 gallon trash barrels right in the middle of the stations at a shooting range used on weekends. The bluebirds were nesting in empty shotgun shell boxes surrounded by empty shot shells down in the barrels.

Nest in pipe. Photo by Keith Kridler.   Keith Kridler has seen bluebirds and titmice both nest in this 6" interior diameter pipe. The nest in the photo is 17" away from the end of the pipe. In 2007 it was occupied by a Black Widow spider.

HOFI nest in wreath.  

House Finches don't often nest in nestboxes. But they have used a wreath more than once. Photo by Bob and Kim Wolfe of Georgia.

This one is particularly funny because the wreath says "Home is where you build your nest." Note the nest in the back of the little birdhouses. Four House Finches grew up in it.

Bluebird nest. photo by Keith Kridler.   Eastern Bluebirds nesting in an opening in a metal building that is 4.5" tall by 5.5" wide. Photos by Keith Kridler. There are 21 nestboxes up in this park, with six other pairs of bluebirds nesting, but they still chose this spot.

Titmouse nest in fan. Photo by Chris Asmann.   This (Titmouse?) nest was built in the fan of an industrial air conditioner. The occupants would have been struck by the fan blades when it was on, so it was moved to a nestbox that was strapped to the the air conditioner, but unfortunately it was abandoned, even though it contained 5 eggs. Titmice are not tolerant of nest site disturbance. Photo by Chris Asmann.

    To many the bluebird is the favorite of all birds. It is one of the most domesticated of our wild birds and readily takes possession of boxes erected for its accommodation or builds its nest in the crannies about farm buildings.
