Ovenbird
Seiurus aurocapilla
Ovenbirds are large wood warblers and may sometimes be confused by the untrained for a thrush. Adults measure 11–16 cm (4.3–6.3 in) long and span 19–26 cm (7.5–10.2 in) across the wings. They weigh 19 g (0.67 oz) on average, with a range of 14–28.8 g (0.49–1.02 oz). Among standard measurements, the wing chord is 6.8 to 8.3 cm (2.7 to 3.3 in), the tail is 5 to 5.8 cm (2.0 to 2.3 in), the bill is 1.1 to 1.3 cm (0.43 to 0.51 in) and the tarsus is 2 to 2.3 cm (0.79 to 0.91 in). They tend to be heavier in winter and particularly at the start of their migration. Voice: The main song of the ovenbird is a series of strident, relatively low-pitched, bisyallabic motives repeated without pause about eight times and increasing in volume. Usually, the second syllable in each motive is sharply accented: "chur-tee' chur-tee' chur-tee' chur-tee' chur-TEE chur-TEE chur-TEE!
