\"\"As the most literal of helicopter parents, a ruby-throated hummingbird mom (RTH, Archilochus colubris<\/em>) takes hovering to a whole new competitive level.<\/h5>\n
In the case of this feathered sprite (2.8 \u2013 3.5\u2033 long, including bill, and just over 1\/10 of an ounce), though, the word \u201chover\u201d has more to do with the ability to fly than with over-protective child rearing. Which is not to suggest that an RTH mom is neglectful. Far from it\u2026 she\u2019s just a bit Type A.<\/h5>\n
\"\"Both male and female RTHs winter in Central America or along the southern tip of Florida, but from the moment a gal returns to her summer stomping grounds in the eastern half of the US or southern Canada, she\u2019s all go-go-go\u2026 because her biological clock is ticking like a stopwatch.\u00a0 Barely hesitating to catch her breath, the first order of business is to find a baby daddy. She\u2019s not looking for ever-after; Mr. Right-for-Now will do as long as he\u2019s strong and handsome. Since the males of her clan aren\u2019t the slightest bit interested in becoming a Mr. Mom this arrangement suits everyone just fine. With barely a look backward by either party following their four-second assignation, he jets off to find another hookup, and she speeds away to shop for flower-down to line the bassinet.<\/h5>\n
It takes about six days for this mom-to-be to fashion a nest barely wide enough to hold a bottle cap, and tether it to a foundation with strands of spider silk. RTH nests are most often built on a tree branch but unusual alternatives, including loops of chain or extension cord, have proven acceptable in a pinch. Darting back and forth, the female will weave bud scales, lichen, hair or fur, and other creatively repurposed found objects into a cup-shaped cradle. Next, she\u2019ll adorn the nest with lichen and moss, finally lining the interior with a soft, insulating layer.<\/h5>\n
Once the nursery has been prepared and decorated, 1-3 eggs the size of your pinkie fingernail will appear, and then\u2026 a pregnant pause.<\/h5>\n
Think about it. The longest stretch this single mother ever sits down, during her entire life, is to incubate a clutch of future hummers. Imagine, if you will, the kind of patience, willpower, and elevated estrogen levels it takes for a creature who has lived on the wing, perpetually flitting hither and yon since leaving her own natal nest, to STOP\u2026\u00a0 settle in\u2026<\/h5>\n

During this time, the newly stationary creature will leave her nest only for brief breaks to stretch or grab a bite to eat. She\u2019ll anchor there, day and night, rain or shine. No baby shower, no friends stopping by to say hello; they\u2019re all brooding their own nest eggs. No television, even though this would be a great time to binge watch David Attenborough\u2019s The Life of Birds<\/em>. No smartphone at the ready to check email, take selfies, and whine to everyone on Facebook that she is bored beyond reason.<\/h5>\n
Heck, when I manage to stop and meditate for ten minutes two days in a row I feel like a Zen Master.<\/h5>\n
Once the chicks hatch it\u2019s back to her normal hyperactive life\u2026 and then some. RTH nestlings are naked and wobbly-headed, with an appetite that dwarfs their bitty bodies. For the next few weeks, Mom will need to make 1-3 grocery runs per hour, from dawn to dusk, regurgitating the food she\u2019s foraged and hauled home in her belly into the beseeching beak of each precious child.<\/h5>\n
Once the babes fledge at 18-22 days old they\u2019ll disperse among the branches\u2026 not too far away from the nest or each other initially, but spaced out enough to make dinner deliveries much less efficient for their harried mother. As the kids grow stronger and bolder, they\u2019ll spread out further, testing their own wings\u2026 and Mom\u2019s ability to be everywhere all at once.<\/h5>\n
\"\"Oh, and somewhere in that frantic schedule, this solo parent also needs to down enough calories to keep her own metabolism running on all cylinders.<\/h5>\n
Luckily, she flies like a super-charged, hyper fuel-efficient, \u00fcber-nimble helicopter. Hummingbirds have been known to reach speeds of nearly 35 mph (55 kph), which is certainly impressive. Not record-breaking among the avian set, though. The difference is that most of the planet\u2019s fastest feathered fliers reach their top speeds in a dive, asking gravity to add a significant boost to their velocity. Acrobatic RTHs can fly straight and fast, too, but it\u2019s their ability to achieve what those avian missiles can\u2019t\u2014a true hover\u2014that sets them apart.<\/h5>\n
This isn\u2019t using a thermal to save energy, like vultures, ravens, petrels, and other long-winged birds do. That\u2019s soaring. Hummingbirds move their wings in a figure-eight pattern at over 50 beats per second, allowing them to stop on a dime or adjust their position up, down, forward, or backward. That frenetic rhythm is also creates the humming noise that\u2019s the source of their common name.<\/h5>\n
It also helps that the lady\u2019s jet fuel of choice is syrup. Flower nectar, to be more precise, accounts for approximately 90% of an adult hummingbird\u2019s daily caloric intake. RTHs and other hummers have a large surface-area:body-mass ratio, which means they lose a lot of heat in the normal course of living. Plus, their metabolism is so high they have to enter a torpor once a day, between sunset and sunrise, just to make it through the night without having to recharge.<\/h5>\n
Unlike the sugar-water mixtures backyard bird enthusiasts cook up to fill hanging feeders, blossom juice consists of more than just sucrose (from which plain white table sugar is derived). Flowers also produce fructose and glucose, as well as amino acids, antioxidants, calcium and other trace minerals, lipids, phosphates, and some protein. Other sources of protein include insects that have found their way inside the flower\u2019s throat, where they are slurped up along with the nectar. Hummingbirds will also glean aphids from plants, pluck spiders from their webs, and nab flying insects mid-air. During breeding season, female RTHs spend a lot of time catching insects because nestlings need a high protein diet to grow and develop properly. Once they mature they\u2019ll gradually switch to the high-carb diet of an adult.<\/h5>\n
\"\"As befits a fast-paced life, in barely the blink of an eye (or the wing-beat of a hummingbird) summer is over. Male RTHs often head south first, in early August. Females tend to delay departure until late August or sometime in September. After months of feeding others\u2014our feathered Supermom may have raised as many as three broods in a single season\u2014the time has come to focus on self-care, and on building enough fat reserves to power through an 18-22 hour non-stop flight across the Gulf of Mexico.<\/h5>\n
The last of her children have left the nest and are, hopefully, ready for their first migration. RTHs are solitary migrators so Mom\u2019s helicopter parenting days are over\u2026 until next year.<\/h5>\n
Because a mother\u2019s work is never really<\/em> done.<\/h5>\n
