Shelter Birds need shelter to protect them from the weather and from predators, and to provide a place in which to roost at night.
Shelter can also provide nesting spots for birds to raise their young.
The best shelter is a mixed planting of low and medium sized evergreen and deciduous shrubs, medium and tall coniferous trees, and tall deciduous trees. If you can plant shrubs and trees that also provide food from either berries or nuts, then your plantings will serve a dual purpose. Even with the best plantings in our gardens, some birds still need help finding places in which to raise their young. Many birds evolved in old growth woodlands that had old and dead trees in which birds could easily hollow-out cavities for homes. With most of these woodlands now converted to farmlands and subdivisions, along with our quickness in removing dead, damaged and very old trees from our yards, there are very few places for tree-nesting birds to nest.
