Greyish Mourner

The greyish mourner is 19.5 to 20.5 cm (7.7 to 8.1 in) long and weighs 33 to 38 g (1.2 to 1.3 oz). Males of the nominate subspecies have a gray head with a hint of a crest at the rear of the crown. Their upperparts, wings, and tail are gray with a tinge of brown on the wings and tail. Their throat is light gray and their underparts slightly darker gray but lighter than the upperparts; their belly has a slight yellowish green tinge. Females are very similar with the addition of fulvous edges on the wing and tail feathers. Subspecies R. s. Voice: The greyish mourner's song is "varied, in tempo; normally a rising series of sharp ih notes, ending in some loud, explosive Itch notes". The notes may be separate, repeated as a rattle, or decelerating, and sometimes the last note is omitted. It also makes "a slowly ascending series of clear, whistled whew notes".
