Chamaea fasciata
The Wrentit (Chamaea fasciata) is a fascinating, small passerine bird, unique as the sole member of its avian family, Chamaeidae. Measuring 13-16 cm (5.1-6.3 in) in length with a long, often cocked tail making up about half its body, and weighing a mere 10-15 grams (0.35-0.53 oz), it presents a rather nondescript appearance with dull olive-brown to grayish plumage dorsally, fading to buffy-brown or grayish-white on its underparts. Its most distinctive field mark is a striking pale, yellowish-...
Found primarily in dense, shrubby habitats such as chaparral, coastal sage scrub, oak woodlands with thick understory, and riparian thickets, generally from sea level up to 1,500 meters (5,000 feet) elevation.
