17cm. Black crown and eyestripe, white supercilium, rufous nape, and cinnamon-brown upperparts streaked with black and white. The wings and tail are barred with black and greyish-white. The underparts are white. Young birds have duller upperparts and buff underparts.
This species has in the past been treated as three species and a new paper is proposing to use that treatment again. These are here treated as groups:
Near Laguna la Joya is a population of medium size that probably originated as a hybrid population when the large and the small forms came into secondary contact. The paper referred to above argue that this is a narrow, stable zone of contact.
Forest or open woodland, scrub, second growth and savanna.
It builds a spherical nest with a side entrance and lined with seed down in thorny trees or shrub. The female alone incubates the 3-5 brown- or black-spotted white eggs for about 2 weeks until hatching. The young fledge after a further 2 weeks.
The diet includes insects, spiders and other invertebrates.
