One reason why these birds build multiple nests is to confuse their predators which attack the young ones when the parents are away.

The Carolina wren's nest

This bird builds its nest in open cavities like tree hollows, overhangs and crevices which are about 3-6 ft (0.9-1.8 m) above the ground. Apart from these usual nesting sites, they also build their nests in discarded mail boxes, garages, old hornet nests, tin cases, old boots and sometimes even in a nest box. The males and females build the nests together in different places before they finally settle for one location. While the first nest takes some time to build, the next nests are built within a week. Wrens use plant matter like dried leaves, twigs, straws to build to build cup-shaped domed nests to lay their eggs in. During the incubation period, females sometimes line the inner side of the nest with snake skin. The nests are generally 3-9 in, in length and 3-6 in, in breadth.

The Carolina wren's call

Unlike other wren species, only males sing the rich tunes with notes that often sound like 'tea-kettle-tea-kettle'. Females accompany them and often add their own chattering notes to the melody. Their songs are used to mark their territory, making other birds aware of their presence in that region. Both sexes can give out loud alarm calls when they feel threat approaching.
