Sora Rail

Sora Rail [now Sora]
Ortygometra carolinus, Linnaeus [now Porzana carolina]
Octavo edition, plate 306
“Not many years have elapsed since it was supposed by some of the inhabitants of those districts to which thousands of this species of Rail resort at particular periods, that the Soras buried themselves in the mud at the approach of cold weather, for the purpose of there spending the winter in a state of torpidity. Many wonderful tales were circulated to convince the world of the truth of this alleged phenomenon; but the fact was, as you will naturally anticipate, that the birds merely shifted their quarters, as no doubt they will continue to do, so long as the climate becomes too cold for them in winter. Prior to the days of [Alexander] Wilson, very little indeed had been published respecting the habits of our birds. Superstitious notions and absurd fancies occupied the place of accurate knowledge in the minds of people too earnestly engaged in more important pursuits, to attend to the history of the animals around them; and with respect to the Sora in particular, I have no doubt that the settlers in our original forests cared very little about them, farther than that, when well cooked, they afforded a very savoury dish . . . Having seen flocks of Soras winging their way close over the waters of the Gulf of Mexico, and between Cape Florida and the main shores of the Carolinas, in the month of April, when they were moving directly towards Cape Lookout, I have very little doubt that many return in the same track . . . Their notes are shrill and short, but reiterated, like those of Rallies crepitans, although by no means so loud and disagreeable.”
