+++The shrill, whistling chorus of the spring peepers, a brief recorded sample of which is provided below, normally begins to swell in marshy areas along the Trail a week or so before the vernal equinox, and is one of our area’s earliest signs of the advent of the season.


+++There follows on this page first the text, translation, and explanation of the first published attempt to describe the spring peeper scientifically; this description was an important part of the effort to assign to the frog a Linnaean binomial, whose purely morphological designation (the only scientific option available in that era) was subsequently refined by later researchers into a more precise, neo-Linnaean trinomial, viz., Pseudacris crucifer crucifer. Then a few details are noted concerning the naturalist and explorer Alexander Philipp Maximilian (1782-1867), prince of Wied-Neuwied, who undertook a journey of scientific investigation in North America from 1832 to 1834.
+++Good collections of photographs of the spring peeper may be found on the web sites of the Virginia Herpetological Society and Berkeley.


Prince Maximilian’s scientific description of the spring peeper:

+++Hyla crucifer [= spring peeper (see the explanation below)]: Eyes large; snout somewhat rounded; legs long and slim; large stomach covered with granules; forefoot with four fingers, of which the second (counting from the outside) is the longest; hind foot is five-toed, the second toe from the outside the longest, the inner and outer toes being shorter and of roughly the same length, the remainder are short, with gaps between them; coloration: basic color of the upper portion is yellowish-grey or brownish-grey, and the back is marked by a broad St. Andrew’s cross of a darker color. Frequently this marking consists of several angled stripes whose tips, pointed forwards, create an even broader St. Andrew’s cross on the back and neck; in other cases the lines are not solid and along their lengths run a couple of stripes which create pointed angles directed forward; the forward crossing frequently directs its branches toward the raised eyelids between which is located a bend the point of whose angle is directed backwards; a dark stroke that runs through the eyes continues through to the side of the stomach; throat dark grey-brown; skin of the throat beneath the edge of the lower jaw blackish brown; stomach soiled yellow; shank with obscure dark bends. Legs and shanks overflow on the underside a reddish-flesh brown.
+++A small, lively frog whose body from snout to rump’s end measures one inch. The cry is a clear whistle that rises somewhat at its finish. During mating season, the throat took on a spherical shape.

An explanation of the scientific designation of the (northern) spring peeper

+++“Pseudacris,” the genus (the first part of a scientific name, or taxon, normally derived from Greek), means “false cricket” (or locust, or grasshopper — the Greeks did not rigorously distinguish these). The cry of the NOVA peeper, which is entirely the product of the hormone-driven male defending a tiny plot of muck as it seeks to attract a mate, deceptively (pseudo-) suggests that of certain types of cricket (acris); the similarity is readily apparent to anyone who has ever heard thousands of overlapping cries during the great chorusings of early spring. “Crucifer,” the species (and second portion of a taxon, normally derived from Latin), means “cross-bearing,” after the fact that the back of the frog is marked with an “X” that is more or less irregular in shape. (The repetition of “crucifer,” which extends the bi- to a trinomial, indicates that our frog is a distinct subspecies.) So, the combination of Greek and Latin elements is intended to telegraph a succinct description of the frog in question — and does so successfully, in fact, although, for want of common study of the so-called classical languages that had already begun to evaporate from curricula after World War I, increasing numbers of not only scientists but also both scholars and intelligent laypersons have come to find such encoding obscure.

Alexander Philipp Maximilian, Karl Bodmer, & the Reise in das Innere Nord-America

+++Alexander Philipp Maximilian (1782-1867) was a Prussian aristocrat, prince of Wied-Neuwied, which was a very small state that was eventually confederated into the German Empire formed in 1871 under Otto von Bismarck. A naturalist largely self-taught (not at all unusual in that era) and explorer, Prince Maximilian first undertook to describe the spring peeper scientifically in print. Because he had frequently observed the frogs, those further to the American west and north where he travelled, in bushes and small trees, the prince himself originally selected “Hyla” (which is derived from the Greek word for “forest” or “woodland”) as the name of the genus. When it was later noted, however, that similar frogs in Virginia and elsewhere prefer the ground, for reasons of taxonomic precision two additional genera came to be distinguished from Hyla (treefrogs): Acris (cricket frogs) and Pseudacris (chorus frogs).
+++“Prince Max,” as he is referred to more casually by modern zoologists (now scientists, of course, and naturalists no longer), undertook two daring expeditions during his long life: in 1815-17 he traveled in southeastern Brazil, and in 1832-34 in North America (chiefly along the Ohio and Missouri Rivers). For the latter journey he commissioned the Swiss artist Karl Bodmer (1809-1893) to accompany him so that it would be possible to augment with a detailed visual record the written one that the prince planned to keep and subsequently to publish after he had revised and polished the notes upon his return. Bodmer not only succeeded in creating an impressive collection of images of flora and fauna (to include those of the spring peepers near the top of this page) but also produced an array of detailed, distinctly unromanticized representations of the daily life, customs, and rituals of a number of Indian tribes. Incorporated into the extensive pictorial record were carefully crafted vignettes, portraits of individuals and groups, and meticulously detailed tableaux of textiles, utensils, weaponry, etc., among which are found jealously protected ritual objects such as these two pouches — both perhaps medicine bags — the one wrought from the corpse of a skunk, the other an intricately folded wrapper of animal skin or cloth:


Images of this sort and the lucid observations in Wied-Neuwied’s written account retain considerable ethnographic value because the bulk of the native material culture of the era was obliterated during the westward expansion of the United States in the latter half of the 19th century. Detailed knowledge of a number of tribal practices — those concerning the medicine bag, for example — continues to remain wanting as well. Although any modern student of aboriginal American religions certainly would be aware that fetishes were believed to be imbued with immense power and lay at the very heart of tribal spirituality, the fashioning of the medicine bag and the reasoning informing the selection of its contents were normally shrouded in the greatest secrecy. The bones and/or skins of various species of toad and frog, which seem to have been included regularly among such contents, were thought capable of curing or killing, depending on the dosage administered — a principle that is also fundamental to modern scientific pharmacology. Also, because these amphibians, creatures of both the water and the land, are not only liminal but also undergo metamorphosis, they were probably held to be extraordinarily uncanny. Consequently, their relics would have come to be regarded as especially numinous and, therefore, especially efficacious tools whose employment in a system of magical practices inextricably intertwined religion with a very practical and encyclopedic knowledge of the genuinely medicinal properties of things found in nature.
+++Upon returning to Europe, the prince spent several years preparing his material and publishing short, scientific papers based on his notes and observations, until, between 1839 and 1841, he published a two-volume study, Reise in das Innere Nord-America in den Jahren 1832 bis 1834 (Journey into the Interior of North America, 1832 to 1834), in which there appeared the first effort, whose text is located near the top of this page, to describe the spring peeper and to provide it with a Linnaean binomial.
+++The prince expired peacefully in his homeland at the age of 84, having lived an unusually long life for a man who took very unusual risks. Although he seems almost miraculously to have avoided contracting any of a wide range of exotic tropical diseases such as malaria during his earlier extended exploration of Brazil, he had apparently lost most of his teeth to scurvy by the time he concluded his travels in North America, largely because his diet had consisted almost exclusively of heavily salted meats and dried grain, foods that resist spoilage quite well but are nutritionally deficient in vitamin C.
