The house wren is a common bird that can be found through out most North, Central, and South America. They get their name from the fact that they are a cavity
nester. They will nest in nest boxes, tree hollows, or almost any other cavity that is available. Often they will drive away other birds, even destroying eggs or killing young that are already in a nest, to claim a preferred cavity.
The choice of a nesting cavity is important because external factors can negatively affect the productivity of the wren couple. Environmental factors like temperature, temps above 105 or below 65, can destroy the eggs. Nesting parasites can also be a problem, once the chicks hatch, but the clever house wren will often include spider egg sacks when building their nest. When the spiders hatch they eat any parasites that make their way into the nest which helps keep the nestling safe. I photographed this house wren at the Carpenter Nature Center.
