Paint-billed Crake

The paint-billed crake is 18 to 20 cm (7.1 to 7.9 in) long and weighs about 40 to 70 g (1.4 to 2.5 oz). One specimen had a wing of 20 cm (7.9 in), a tarsus of 2.8 cm (1.1 in), and weighed 43 g (1.5 oz). The species gets its common name from its red and yellow bill; it has bright red legs. The sexes are alike. The nominate subspecies has a brown crown, nape, and upperparts including the tail. Its throat is white and its face, throat, and breast are gray. Its flanks, belly, and vent are barred black and white. N. e. olivascens is similar but darker and with less white on its throat. Voice: The paint-billed crake's song is "a long, gradually accelerating series of up to 36 staccato somewhat yelping 'kjek' notes". Its calls include "frog-like, guttural, buzzy, single notes", "a mellow soft purring", and "a sharp 'twack'".
