The restless, agitated behavior exhibited by migratory birds when the season to migrate arrives but they are caged and cannot go. The bird flutters, hops, and orients toward the direction it would fly if free. The pull to go, expressed as the inability to stay still. The word names what it feels like to be built for a journey you cannot take.

The line of debris deposited at the highest reach of the tide or storm surge on a beach — seaweed, driftwood, shells, crab shells, feathers, plastic, rope, and whatever else the sea was carrying. The wrack line is the ocean's high-water mark, redrawn with every tide, and it is one of the most ecologically productive zones on a beach: the decaying organic matter feeds sand hoppers, flies, shorebirds, and the entire web of life at the land-sea boundary.

Already entered in the main file — flagging here as a core tracking/sign term. A wallow is one of the most visible and long-lasting pieces of animal sign on a landscape. Bison wallows on the Great Plains were still identifiable decades after the herds were gone.

 A depression in the ground created by large animals — bison, elk, boar, rhinos — rolling and rubbing in mud or dust. Wallows serve multiple purposes: cooling, parasite removal, scent-marking, and social display. Old bison wallows on the Great Plains persisted for decades after the animals were gone, holding water and growing different vegetation than the surrounding grass — ghost baths.

A flock of ravens. The name comes from a medieval belief that ravens were neglectful parents — that they were unkind to their young. The science doesn't support it, but the word persists, carrying its dark folklore.

The perceptual world of a particular organism, defined by what its senses can detect. A tick's umwelt is butyric acid, warmth, and hair. A bat's is echolocation returns. Yours is whatever you've trained yourself to notice. The word names the fact that no two species inhabit the same reality — each lives inside its own sensory bubble, and what it cannot perceive does not exist for it.

In tracking, the continuous sequence of sign left by an animal moving through the landscape — not just footprints but disturbed vegetation, scuffed bark, broken spider webs, displaced stones, bent grass, and the faintest compressions in duff. A trail is the full narrative of passage, of which tracks are only the most legible sentences. Following a trail when the tracks disappear is the test of a tracker — reading disturbance rather than impression.

The impression left by an animal's foot in soil, mud, sand, snow, or dust — a single print that records the weight, gait, speed, and intention of the creature that made it. A track is not just a shape; it is an event frozen in substrate. The depth of the toe pads, the presence or absence of claw marks, the spacing between prints, the splay of the toes, the ridge of mud pushed up at the edges — all of it is information, readable by anyone who learns the language.

 A short-term state of reduced metabolic activity and body temperature, entered by some animals to conserve energy. Hummingbirds enter torpor nightly, dropping their body temperature by as much as 50 degrees Fahrenheit. Unlike hibernation, which lasts weeks or months, torpor is measured in hours — a daily descent into near-death and a daily return.

The wavering or deviation of an animal's tracks from the median line — visible when the animal is tired, injured, or heavy with young. A straight-tracking deer that begins to sway is telling you something about its condition without you ever seeing the animal.
