There are no contractors a bird can hire to build a family home.  If you want a house, you have to build it yourself.  The male Wren does the majority of construction, but he is clearly supervised by the female.  She can also be seen rearranging the design as the project moves along.  This might sound familiar to you.

You will see the product of 12 hours of construction over a 24-hour period — collapsed into a 1 minute video. Leaves, pine straw, and bits of bark are woven into a ball with a hollow center. If you’ve ever left your garage door open during nesting season, and been faced with removing a Wren nest, then you can attest to a Wren’s weaving skills!
