Saturday Surprise — Hummingbirds

Spring.  I am ready for it.  Although the winter has been relatively mild, except for the first two weeks, I am nonetheless tired of grey skies, of rain/snow/sleet, and of having to don a jacket, or worse yet, coat/hat/gloves every time I go out.  And so, as my thoughts turn to spring, to warmth and sunshine, to flowers filling my teeny-tiny yard in a profusion of colour, and to the happy sounds of children’s voices playing in the yard and the “thunk-thud” sound their balls make hitting my kitchen windows.  Well, okay … some things I look forward to more than others.  Still …

As I was pondering the advent of spring, I happened across an article about one of my favourite spring/summer critters, the hummingbird.  I’ve always realized these were special little birds, but I never realized quite how special until I read this.  It is actually an excerpt from a book, Tamed and Untamed: Close Encounters of the Animal Kind, by Sy Montgomery and Elizabeth Marshall Thomas.  I found some of this information so fascinating … it made me wonder how these tiny little critters whose hearts beat more than five times faster than ours, and who consume their body weight in food – bugs and nectar – many times over, can even survive.  I thought I would share this with you, along with some adorable pictures of these little guys.  We have a pair that visit our sunflowers each summer, and I am enthralled by them.  So, to start your weekend out right, take a look at some of these amazing critters!

They flash in front of flowers and feeders for seconds, wings a blur, and then whiz away. Next they’re back — but before you can gasp at the beauty, they’re off again.

A glittering fragment of a rainbow; a flamingo comet; a living gem: All of these metaphors struggle to describe the evanescent magic of hummingbirds.

Too often, people “rescue” baby hummers prematurely, Brenda told me. It’s rare to find a hummingbird nest, but if you do, back off, leave the babies alone, and, using binoculars to watch from a safe distance, observe the nest without looking away for at least twenty minutes. “So few people can just sit still and watch anything that long,” said Sherburn. But if you so much as blink, you could miss the mother’s return. A mother hummingbird leaves the nest from 10 to 110 times a day to find food for her nestlings.

hummingbird-9To survive, a hummingbird must consume the greatest amount of food per body weight of any vertebrate animal. A single bird may drink its own weight in a single visit to your feeder — and seconds later come back for more. That’s because a hummer breathes 250 times a minute. The resting heartbeat is 500 beats per minute, and the heart can rev to 1,500 a minute in flight. A film I watched claimed that a person as active as a hummingbird would need to consume 155,000 calories a day — and the body temperature would rise to 700°F and ignite!

An adult hummer visits an average of 1,500 flowers in a day. If the nectar were converted to a human equivalent, that would be fifteen gallons a day. But few people realize that insects are equally essential. Each hummingbird needs to catch and eat six to seven hundred bugs a day. (So spraying insecticide in your yard is like hiring a hummingbird exterminator.)

The food requirements mentioned above are for a single hummingbird. A mother caring for nestlings (there are usually two) needs even more. Lucky for us, Sherburn had access to a fine compost pile with plenty of fruit flies, and her husband, Russ, was willing to catch fresh ones for us every day.

hummingbird-10.jpgEach morning, when normal people were grinding coffee beans, Brenda would take out her mortar and pestle to grind ash-frozen fruit flies. Then she’d mix them with nectar, vitamins, enzymes, and oils. Because this food spoils easily, we had to make a fresh batch several times a day. From dawn to dusk we would deliver this to the babies’ gaping beaks — by syringe — every twenty minutes.

Sherburn was one of a handful of specially trained and deeply committed wildlife rehabilitators qualified to do this. I was honored to help. But for these fragile nestlings, each moment was fraught with danger. Miss a feeding and the babies could starve. Worse, explained Sherburn, was what could happen if you fed them too much. “They can actually pop,” she told me.

Hummingbirds are little more than bubbles wrapped in feathers. Our bodies are filled with organs; theirs are full of air sacs. Their feathers weigh more than their skeletons, and both their bones and their feathers are hollow. It’s hard to imagine anything more fragile.

Sherburn lives in California, which boasts several species; as their feathers grew in, our babies revealed they were Allen’s hummingbirds. To impress a female, a male Allen’s performs a plunging flight that makes it the fastest bird for its size in the world. In terms of body lengths per second, it even bests the space shuttle!

Ruby-throated Hummingbird

On the East Coast we have only the ruby-throated hummingbird, named for the flaming red throat patch on the males. These birds are equally spunky: Each fall they undertake a punishing migration across the Gulf of Mexico, which may demand twenty-one hours of nonstop flight.

hummingbird eggsIt’s shocking to realize that someone who hatches out of an egg the size of a navy bean is capable of such feats. But equally shocking is the gauntlet of dangers a hummingbird may face on an average day. Hawks, jays, squirrels, crows, even dragonflies eat them. They tangle in spiderwebs searching for insects (they also use the silk in their nests, to give them stretch as the nestlings grow). They fly into our windows; they’re hit by our cars; they’re poisoned by our pollutants. The most common reason for any bird’s admittance to wildlife rehab is also our fault. It’s abbreviated on forms as CBC: caught by cat.

And yet we can help. Put out a feeder. Plant nectar-rich flowers. Keep a compost pile. Support a wildlife rehab center.

hummingbird-4Reasoning that surely a bird so tiny with feathers so brilliant must be born anew each day, the Spaniards who first encountered South America’s hummingbirds called them “resurrection birds.” This names the gift these birds offered us that summer, with each fleeting glimpse. They force us to see the world made new each time, and teach us to believe in ordinary miracles.

Amazing, don’t you agree?  Now that you have peace in your heart (yours only beats between 60-100 times per minute), you can now go out and have a wonderful weekend!  Keep safe and have fun!

  1. Jill, we also the love the birds. We have several bird feeders and a fauna that attract all kinds of birds, including the hummingbirds. Just a few minutes ago, we saw finches and robins. The robins are much bigger and tend to scare the little ones away. Keith

    • We don’t have feeders, though I might consider that this year, but we plant sunflowers in our tiny front “garden” each year, and the hummingbirds and finches seem to love those, so we are treated to a steady stream of delightful winged-visitors each summer.

    • I love them too! So tiny, yet so productive and beautiful to watch. What do you plant in your garden? We have only a very small area … about 2′ x 6′ … but we plant a wild array of flowers, including sunflowers, for they are Natasha’s favourite and they attract hummingbirds, funches and other small birds that are a delight to us! Hugs!!!

  2. Good Morning my friend. We feed our hummers, as I call them, each year. They are a nosy and noisy bunch. We have a bully, that chases the others away from the feeder. Can’t wait for them to return this spring. – Be safe, take care.
