Band-backed Wren
Campylorhynchus zonatus
This large wren breeds in lowlands and foothills from sea level up to 1700 m altitude in thinned forest or open woodland, scrub, second growth and groves around houses. It mainly occurs on the Caribbean side of the Central American mountain ranges. Its large spherical nest has a wide side entrance and is constructed 2 – 30 m high in a tree or shrub, often hidden amidst bromeliads. The female alone incubates the three to five unmarked or lightly brown-spotted white eggs for about two weeks to hatching, and the young fledge in about the same length of time again.
