Melanotis hypoleucus

Medium68 gForest

The blue-and-white mockingbird is 24.2 to 28 cm (9.5 to 11.0 in) long; 20 specimens had a mean mass of 68 g (2.4 oz). The adults' upperparts are a dull slate blue that is slightly brighter on the crown. The wings and tail are slaty black. A conspicuous black "mask" covers from the lores past the eye. The underparts are white darkening to bluish or slate gray on the flanks and vent area. The juvenile has a similar pattern but its upperparts are dull slaty gray instead of blue. Voice: The blue-and-white mockingbird's song has been described as "an amazing medley of bird notes... a rapid series of monosyllables, now a shrill squeak, now a whistle, now a guttural croak...certainly not musical or harmonious". It also has a wide variety of calls.
