The month of August is peak hummingbird season in the Arizona Central Highlands. Each day at the Bird Barn, we hear from customer after customer about the large number of hummers being seen at their feeders. One customer told me he went through 44 pounds of sugar last week! 

Globally, there are approximately 350 hummingbird species — all of them occurring in the new world — with the largest number of them occurring in Central and South America. In my lifetime, I have seen 68 different hummingbird species — not even 20%.  That just means I need to do a whole lot more birding!

A search in eBird indicates that there have been 23 different hummingbird species documented in the United States. While many people consider Arizona to be the hummingbird capital of the United States, we are actually tied with Texas for the number of documented hummingbird species — 17. Folks living east of the Mississippi get to see only one hummingbird species on a regular basis — the ruby-throated hummingbird.

Eleven different hummingbird species have been documented here in Prescott over the last 40-plus years.  In the 29 years I have lived in Prescott, I have had seven different hummingbird species in my yard — Anna’s, black-chinned, rufous, broad-tailed, calliope, Costa’s and broad-billed.

I frequently comment that hummingbirds are one of three species that keeps Jay’s Bird Barn in business. These flying jewels really capture people’s hearts and provide hours of entertainment. They really are a wonder, when you consider some of the statistics about hummingbirds.

For example, the smallest hummingbird in North America is the calliope hummingbird. This tiny species weighs only 2.7 grams. This means it would take 10 calliope hummingbirds to weigh one ounce! That means you could mail 10 calliope hummingbirds with a single first-class stamp!

Another amazing ‘gee-whiz’ fact is how far hummingbirds migrate. The ruby-throated hummingbird is famous for flying nonstop across the Gulf of Mexico twice each year — when it migrates south in the fall and when it flies north in the spring.

Rufous hummingbirds, common summer visitors here in Prescott, are considered the world’s longest migrator, based on body length. If you divide the length of the bird into the distance it travels, this species sets the record. Rufous hummingbirds are found as far north as southern Alaska in summer and as far south as Central America in winter.

Our common Anna’s hummingbirds are truly amazing in their ability to stay at high elevations in winter, enduring sub-freezing temperatures — even single-digit temperatures! Anna’s hummingbirds have the ability to go into a state of torpor, akin to semi-hibernation, where they lower their body temperature at night by 40 degrees or more.

I marvel how hummingbirds ‘map’ feeder locations. After being gone for months, having traveled hundreds — perhaps even thousands — of miles, they have the ability to fly back to the exact spot where a hummingbird feeder was hung the previous year.

On many occasions, customers have shared with me how they will have a hummingbird show up outside their window in the spring, flying around the hook on their deck where their hummingbird feeder was hung the previous year. I’ve also heard stories how they will fly in front of windows to get the homeowners’ attention to let them know when the feeder is empty and needs to be refilled. 

This year, more than most years, hummingbirds are more dependent upon human-provided food sources, as there are not a lot of natural food sources available to them due to the poor monsoon season we have had.   

Until next week, Happy Birding!
