It was never a common species, the blue-grey warbler that locals called the jack pine bird. A belated discovery among American birds, it was undescribed by science until the mid 19th century—and then, known only on the basis of a single specimen. The bird's wintering grounds in the Caribbean would eventually fulfill the demands of collectors and museums, but the intricacies of its lifecycle remained a mystery for decades, the first nest only found in 1903. As the already-rare bird became rarer, people could only guess at why. There were just so few birds to look for, their breeding habitat inscrutable amidst the dense, impassable woodland of their Midwestern home. The one clue was the most apparent thing about the bird: its affinity with the jack pine (Pinus banksiana).
Over time, more nests were found—not in the eponymous trees, as might be expected for a songbird, but on the ground at their feet. Data points converged, leading to the realization that not only did the bird nest almost exclusively in proximity to the scrubby pines, but only utilized trees that fell within a specific range: new growth, between five and fifteen feet tall, with branches that swept shelteringly close to the ground. Subsequently, it would be noticed that the greatest volume of specimen collection for the bird had corresponded with years in which historically significant wildfires had impacted the Midwest—fires that, for decades afterwards, had been staunchly suppressed. The pieces fell into place, like jack pine seeds, whose cones open only under the heat of a blaze.
With the bird's total population having dwindled to the low hundreds, a program of prescribed burns, clearcutting, and replanting was instituted, with many acres of land purchased and devoted to the preservation and maintenance of suitable breeding habitat. Concurrently, efforts were made to protect the vulnerable bird against brood parasitism by the brown-headed cowbird.
When the first federal list of protected species was put forward in 1966, the name of the small grey warbler was inscribed beside birds such as the Kauai ʻōʻō and the Dusky Seaside Sparrow.
The ʻōʻō, last of the genus Moho, would be removed from the list in 2023 due to extinction, after thirty-six years without a sighting.
The endling Dusky Seaside Sparrow, a male named Orange Band, would die of old age in captivity in 1987, with his species being delisted three years later.
in 2019, fifty-two years after the creation of the Endangered Species Protection Act, the name of Kirtland's warbler, too, was removed from the list: it had been determined that, with a population now numbering nearly 5000, the jack pine bird could be considered safely stable.
Conservationists continue to work to preserve the breeding habitat of Kirtland's Warbler in the midwestern US, as well as its winter roosts in the Bahamas and neighboring islands (though selective logging has replaced actual burning in recent years, due to the dangers posed by unpredictable fires). It's the kind of effort that it takes to undo the damage we've caused to the planet and its creatures—the kind of hope that we need, to not give up on them, or on ourselves.
The title of this piece is Prescribed Burn (Kirtland's Warbler). It is traditional gouache on 18x24" watercolor paper, and is part of my series Conservation Pieces, which focuses on efforts made to save critically endangered birds from extinction.
