Bird Houses-Bird houses are often hand made decorations that give a secure home for many different types of small birds that nest in them. Bird houses can be made in many different shapes, styles and designs but the common theme among all bird houses is a hole in front for the bird to enter and exit through. Many birds use bird houses to create nests so they can lay their eggs and when they hatch, raise the young until they are capable of flight and go off on their own.&nbsp
