These three figurines do not come from Mantle's Cave, but were among twelve anthropomorphic bird and animal figurines found at Marigold Cave (5MF9), also in Yampa Canyon. Marigold Cave was explored by Scoggin and later excavated by Burgh. Marigold Cave is a large vaulted cave with two ledges, each about 55 m long and 3-6 m wide. Unlike Mantle's Cave, five house floors with hearths as well as masonry granaries were recorded. The site is classified as Fremont and archived notes indicate it was dated to 750 A.D. A calibrated radiocarbon date of 1200 ±60 A.D. was also later obtained (Truesdale, et. al 1993).
Most Fremont figurines were unfired trapezoidal clay anthropomorphs (human figures), elaborately decorated and/or painted, but the Fremont also appear to have made simpler figurines of animals and birds like these. These fragile, unfired birds seem to be made of locally obtained clay. They have perforated holes through the center of their bodies which Burgh speculated were used to hang them. Wooden twigs were attached to depict feathers. These birds are approximately 6 cm in length.
