Free Birdhouse Blueprints

The Wren Box

There are good reasons to use our free birdhouse blueprints to build a home for the wren.

When all other song birds fail to take advantage of a house built for them, the wren may still be counted on. Almost any sort of home from a tin can or hollow gourd on up is satisfactory if put in a safe place and provided with an opening 1" or slightly less in diameter, so the sparrows must stay out.

Three good bird house plans are shown below. The diminutive house wren frequents barns and gardens and particularly any old tree that is partially decayed. He makes his nest in a hollow where perhaps a woodpecker had their hone the year before. However, he is a quarrelsome character, and if he happens to fancy one of the boxes put up for bluebirds, he does not hesitate to take it.

The wren is usually not slow to make himself at home of any boxes, gourds, tin cans, or empty jars placed for his accommodation.

The various species of wrens occupy more or less all of North America, from the Atlantic to the Pacific. The wren is one of our most friendly birds and his presence should be encouraged about every residence.
