The house wren is a tiny little bird that is commonly found living around people in America. They have the largest range of any passerines in the Americas. They can be found from central Canada in the north all the way down to the southern tip of Argentina. Birds that breed in the northern part of their range migrate south into the southern US and Mexico for the winter while birds in Central and South America are not typically migratory.
The house wren is a cavity nester, building their nest in a tree cavity, woodpecker hole, or nesting box. The nest is a cup style made from sticks and lined with a thin layer of grasses and feathers. Although small, they weigh approximately the same as two quarters, they are fierce about defending their territory. They will go to great length to keep other birds, most of which are larger, from nesting in their territory. This includes burying nests in sticks, destroying eggs or even attacking and killing young or adults.
