Session 3 English Language Arts How to Watch Birds Chickadee
If you've always wondered what the perfect partnership looks like to a chickadee, plough to the pages of a Jane Austen novel.
How do birds notice a mate? The approaches of different species are as varied as those of humans. Some birds seem similar Casanovas or fifty-fifty Marquises de Sade, while others seem as ladylike and reticent as the most genteel Jane Austen characters. Cranes and swans have the leisure nosotros humans do to spend months or even years making a permanent selection, fifty-fifty as Arctic shorebirds must make their choice within days, or even hours, of arriving on their breeding grounds then they tin heighten young earlier heading south again.
As with humans, bird species use different combinations of factors to approximate members of the reverse sex activity. The quality and persistence of a male person's song, the free energy and style of his courtship displays, how well a female responds to his overtures, how well the two coordinate dance moves or song duets, the quality and quantity of romantic food offerings, the intensity and color of plumage or body parts — each species uses some combination of these cues, and more, to identify the ideal mate.

Age is an important criterion for birds: almost want the oldest, most experienced mate they can find. Birds don't carry a passport or nativity certificate, so how can they reveal their historic period to a prospective mate? Mockingbirds learn new songs throughout life, so the more than songs in a male'due south repertoire, the older on boilerplate he is. Both male person and female hawks of some species start out with yellow eyes, which over months and years turn orange and so ruddy red. Young Cedar Waxwings have no red tips on their flight feathers; these tiny markings appear and then increase in number as the birds abound older. Yr-former male American Redstarts resemble grayish and yellow females; they are fully capable of breeding, but females prefer mates bearing the black and orange plumage of older males, only settling for a younger one when no older males are available.
For nearly wild birds, information technology's impossible to be also old to make an ideal mate, because for both sexes, the time betwixt a mature bird losing its competitive edge and dying is usually very short, long before the bird is no longer physiologically fertile. One female Laysan Albatross notwithstanding reared a chick when she was at to the lowest degree 67 years old! In only a few species do birds seem to have a "sweet spot" between being too young and also old. The blue foot colour on boobies tends to abound duller with age, yet many of these older males still succeed in alluring mates.
Beyond these very basic criteria, scientists don't sympathize what leads two birds to select each other. Is it a unproblematic thing of proximity and risk? Practise birds flirt? Might some want sparks to fly in a kind of magic before they'll commit? We may use "the birds and the bees" as a metaphor for courtship and sex activity, but our agreement of the fundamentals of just how birds institute and sustain relationships is superficial and rudimentary.
That's okay. As Walt Whitman wrote, "Yous must not know too much, or be too precise or scientific well-nigh birds… a sure gratis margin, and even vagueness — mayhap ignorance, credulity — helps your enjoyment of these things."
Living in Jane Austen'southward Globe
It is a truth universally acknowledged, that a single bird in possession of a good territory, must be in want of a mate. With a fleck of tweaking, Jane Austen's opening sentence in Pride and Prejudice describes many birds, but her depiction of English society in the eighteenth century most closely mirrors the life of the Black-capped Chickadee.
Chickadees lead lives more provincial than did Austen herself, staying within their neighborhood and associating with a small circle of acquaintances season afterwards season, year afterward twelvemonth. To the undiscerning eye their existence may appear to exist goose egg more than "a quick succession of busy nothings," just like Austen readers, observant birders discover individuals and their relationships and dramas within whatever chickadee flock.
Every bit in Austen's world, chickadee flocks have a strict, stable social hierarchy. Chickadees become "marriageable" the spring later their kickoff winter.
Equally in Austen's globe, chickadee flocks have a strict, stable social hierarchy. Chickadees become "marriageable" the spring after their first wintertime. Those young chickadees outset out at the lesser of the social ladder, rising in rank as they get older. Pairs are composed of birds of equal social standing. Elizabeth Bennet could have been a chickadee when she noted about Darcy, "He is a gentleman; I am a gentleman'southward girl; so far we are equal."
Female chickadees tin't help simply wait over the neighborhood males, finding the best singers peculiarly bonny. Like Austen characters, a chickadee'southward "imagination is very rapid; it jumps from admiration to love, from dear to wedlock in a moment," but no English heroine would have mashed-up insects from a lovestruck male. In both worlds, settling honey relationships involves drama, only one time mate choices are worked out, the dénouement is short and sugariness, the consummation private. Some infidelity has always occurred; as Mrs. Bennet might have noted, "I clinch you there is quite equally much of that going on with chickadees every bit with people." Yet in both cases, lasting bonds endure year later on yr.
Chickadee romance surges every bound and ebbs every summer. A pair may not seem like a unit in fall and early wintertime, but one sunny Jan morning, the male starts singing anew, and his mate listens afresh. He may ask her, similar Darcy, "If your feelings are still what they were last Apr, tell me then at in one case. My affections and wishes are unchanged." And only like the previous April, and the April before that, their feelings will not exist repressed. Chickadees probably cannot fix on which hr, or glance, or words laid the foundation, but for still some other season, they settle into domestic felicity.
Information technology worked in Jane Austen's world, and information technology works for chickadees today.

At Concluding My Dear Has Come Along
Complicated relationship dramas are limited to immature chickadees and older chickadees who lost their mate since the previous year. Unlike Colonel Brandon in Sense and Sensibility, an unattached older chickadee would more likely court Marianne Dashwood's widowed mother than the beautiful immature girl herself.
