A medium-sized dove of foothill and montane forest. Brown on the upperparts, head, and chest, with a grayish belly and pale gray corners to the tail. Note the pale streak under the eye and the bare pink facial skin in front of and behind it. Similar to White-eared Brown-Dove, but Amethyst has purplish iridescence on the back of the neck and pale buff under the base of the tail. Voice includes a deep “hoop,” given singly or in series of two or three. Also gives a deep growling sound.
