Querula purpurata
The purple-throated fruitcrow is 25 to 30 cm (9.8 to 12 in) long and weighs 91 to 133 g (3.2 to 4.7 oz). Adult males have glossy black upperparts and duller black underparts. Their throat feathers are dark reddish purple; they are long and square-tipped and form a "shield" to the sides and upper breast. Adult females are overall dull black and lack the shield though they may have a few crimson feathers on the throat. Both sexes have a dark brown iris, a pale gray or silver gray bill with a black tip, and dusky gray to black legs and feet. Juveniles have a dull black crown, wings, and tail.
