The last of the hummingbirdsare passing through my backyard this month. I happened to 
get a couple of great shots of some tiny, charming female calliopes buzzing around my rosemary plants. Because the rosemary is in a planter on deck railing, the photos are looking up slightly at the hummers.
I love to watch hummingbirds (Eyelashes and Hummingbirds, Hungry Hummer Can’t Wait), and calliopes are some of my favorites.
Calliopes breed in the Pacific Northwest, and winter in Mexico; there are no reported calliope nests in Colorado. That means that my backyard is just a pit stop in their travels.
According to Birds of North America (Birds of North America), calliope hummingbirds are the smallest migrating birds in the world.
Safe travels, little ones!

Your work is beautiful. Thank you for sharing it. I was looking for an image of a heron and found yours.
Oh thank you for your kind words. I really enjoy sharing what I see with others, and it makes my day to hear that you enjoy it, too!
Thank you for this beautiful work. I was looking for an image of a heron in Colorado and yours popped up.
I love herons — they just seem so improbable. 🙂
