The Calliope Hummingbird is the smallest bird that lives and breeds in North America and the smallest long-distance avian migrant in the world. It's wintering grounds are typically found in a selective area of south-central Mexico, however, we currently have a wintering calliope in south Nashville, in middle Tennessee, that has been present in that area since October.
Sargent describes this hummingbird as about two-thirds the size of our eastern Ruby-throated hummingbird and along with its small size, its short tail is one of it's identification characteristics.Dec 21st, 2012_Calliope Hummingbird in Nashville, TN.
