The Calliopes arrive along with the Rufous Hummingbirds, but always in lesser numbers. Here’s what the Cornell Lab of Ornithology website says about them: “The Calliope Hummingbird is the smallest bird in North America north of Mexico. Despite its small stature, it breeds in the chilly mountain environments of the northwestern United States. The male’s magenta burst of rays at its throat make it a standout from other hummingbirds. Tiny but tough, these birds are the smallest long-distance avian migrant in the world, spending winters in Mexico and a few small pockets of the southern U.S.” This seems to indicate that they (some at least) follow a migration route similar to that of the Rufous – up the West Coast and down the Rocky Mountains. Here are four photos from this morning – July 10, 2016, Embudo, NM, alongside the Rio Grande.
