Nest

Description:

The Bewick’s Wren’s cup-shaped nest has a base of sticks, grasses, rootlets, leaves, moss, or other plant materials, depending on what the local environment provides. Many contain spider egg cases. The open cup may be lined with feathers, wool, hair, or plant down, with a final inner lining of snakeskin. The male initiates nest building; both sexes participate. The construction process usually takes less than 8 days, though sometimes it can stall for long periods and require weeks to complete. The nest is about 2.5 to 3 inches high and 4 or 5 inches in diameter, the cup about 1-2 inches deep and 2-2.5 inches in diameter.

Habitat:

Bewick’s Wrens usually build their nests in cavities or on ledges within 30 feet of the ground. Males often begin the process, with the female contributing equally by the end. Common sites include rock crevices and ledges, brush piles, abandoned woodpecker nest cavities, outbuildings, nest boxes, and abandoned automobiles.

Notes:

Spotted which wren later in the day. I have both Carolina and Bewick in the garden habitat. They seem to like the space between the pergola beam and the shade cover. They built several nests in this space last year.
