I’m reading Margaret Renkl’s book of brief essays, Late Migrations, which evokes in me a revival of memories not too dissimilar from hers. We are near in age, and though she writes from Tennessee and Alabama, her unsupervised childhood running barefooted through peanut fields and along creek banks at her grandparents’ house feels parallel to my unsupervised childhood running barefoot along creek banks surrounded by small towns and cornfields. I too slept on the screen porch at my great-grandmother’s house, fan running, insects humming, heat lightning brightening the humid summer nights.

Renkl writes about watching Walter Cronkite on television and seeing the Viet Nam War, vivid to us in spite of the screen’s small size and black and white images. As teenagers in the mid-1970s, Renkl and I benefited from fairly liberal sex education classes in high school. I also benefited from a brief era of integrated junior highs and high schools, however; not the case in Birmingham, Alabama. Like hers, my parents scraped by in suburbs close to the city in houses with cement stoops and no porch. Though they eventually made their way into the solid middle class, my folks attained financial stability long after I had left home.

The essays note the change in climate, both cultural and natural, that has occurred over the past six decades. Renkl observes the increasing brevity of Southern winters and wonders how the temperature will affect the migratory birds–will they wait too long to head south? Will their food sources also change, or will the migrants find less to eat to sustain them, especially on the return trip north when they need to power up their bodies for mating and nesting? How will the birds navigate an increasingly human-altered globe-scape, a world of all-night lights and glass towers, wind turbines and redirected rivers? And will native birds survive the aggression or overpopulation of invading species?

I see that last concern in my Pennsylvania back yard, where the number of European house sparrows has probably quadrupled in the past three or four years. A passionate birder friend of mine has told me, flatly, “Kill them.” That seems harsh; in Renkl’s book, she gets the same advice about squirrels in her attic! There are, however, compelling reasons to find a way to discourage these aggressive and noisy little birds (see Todd Holden’s article here). My spouse and I have not yet gotten the heart to destroy birds, though they are enlarging woodpecker holes made in our cedar siding corner-boards and then nesting in the openings. We have had no bluebirds, except the occasional one just passing through, for four or five years. A coincidence? I think not!

The memoir aspects of Late Migrations resonate with me, and so do the essays in which she reflects on what we are losing (on earth and among our Beloveds). The author decides to let the chipmunks continue to reside in tunnels under her house and to leave the squirrels in her attic in peace. I’ve come to terms with our hungry, marauding whitetail deer population, our groundhogs, and the Asian stinkbugs, among other creatures. The house sparrows, though, are as bad as the mugwort, knotweed, and wintercreeper in our perennial gardens and hedgerows. I may have to take more meticulous precautionary steps before next spring arrives.

Meanwhile, I use Cornell University’s Merlin app early in the morning and late in the evening (when the house wrens are less vocal) in an effort to determine which birds are hanging out in our little ecosystem–the birds I can’t see, or that I can’t identify by sight (like the blackpoll warbler). Two evenings ago: a bluebird.

But it was just passing through.
