The last known dusky seaside sparrow died 27 years ago today, in 1987. His coda, the last beat of his avian heart, came either late in the evening June 15 or early June 16. (Some accounts use June 17, but that was probably the day it was reported.)
The species or subspecies (Ammodramus maritimus nigrescens) was non-migratory with a small home range: the mashes dominated by broomgrass on Merritt Island and along the St. Johns, Banana and Indian rivers in Florida.
The last dusky, a male, was nicknamed "Orange" because of the band of that color it once wore. He lived out his final days in captivity, his last home was on Discovery Island at Disney World. Reclusive, he spent most of his time hidden in the tall grass at the bottom of his aviary. Alone, he rarely sang. To what purpose? There was no other dusky to serenade.
If you are it, the very last, the swan song and your species is about to vanish, what would you do?
