Synopsis.
Name
The Lie of the Land. An animal must choose where to settle, and it chooses the way it has always chosen, by a cue: tall grass means cover, open water means a safe place to nest, a certain sheen of light means a pond, a certain plant means food nearby. And the cue is not a guess, it is a reading the lineage has earned, because for a very long time the cue and the quality moved together, tall grass really did mean cover and open water really did mean safety, so an animal that settled where the cue was strong left more young than one that did not, and the reading was built into the chooser because it worked. And then the ground is changed. Not by anyone against the animal: a field is mown for hay on a schedule the birds never met, a shore is lit so that the wet glare of asphalt now shines like water, a marsh is drained and a bright lawn put down, a road laid where the grass grows tall on the verge. The people who change the ground have their own good reasons and mean the animal no harm and mostly never think of it. But the change is fast, faster than the lineage can re-learn what to read, and it breaks the old agreement between the cue and the quality, so the cue goes on firing exactly as strong as ever over ground that no longer holds what the cue once promised. And the animal reads the sign. It reads it correctly, the way it always has, the way that always paid: it sees the strong cue and it prefers that place, settles there, nests there, lays there, and every step of that choosing is right given the cue, no error in it anywhere, the same competent reading that filled good habitat for ten thousand years. Only now the strong cue sits over poor ground, so the animal is drawn to the worst place as surely as it was once drawn to the best, and in a hard case it prefers the poor ground over the good, so the sink fills and the true source, quieter in cue though richer in fact, stands empty beside it. And there the animal settles and does everything right and still does not make it: the nest is mown, the eggs bake on the asphalt, the young go hungry where the plant that fired the cue no longer feeds, and the site takes in more settlers than it returns, an attractive sink drawing them below the rate at which they replace themselves, each one having chosen well by the only measure it had. Nobody lied. The cue did not lie on purpose, it reported what it always reported. The people did not set a trap, they changed their own ground for their own ends. The animal did not err, it read the sign the way the sign had always earned. It is only that the cue was a promise the ground used to keep and no longer keeps, and a promise still spoken is heard as a promise still good, so a signal that once led to life now leads to the sink, and the better ground stands open because nothing about it fires the cue.
Arc
The bend is this: a cue that once tracked habitat quality goes on firing after human change has broken the link, so the chooser, reading the cue correctly as it always paid to, prefers the now poor site and even passes the good one, and the site fills to below replacement. It runs on a cue that a lineage learned because it worked. An animal selects habitat by cues that historically correlated with quality, and the preference for the strong cue is adaptive, built by selection because for a long time the cue and the fitness of the place moved together (Schlaepfer, Runge and Sherman, on habitat selection by cues that once reliably indicated quality). So the reading is earned and not careless, and this is what makes it a trap and not a fault, because there is no chooser wiser than the cue its lineage was shaped to trust. And then human change breaks the link the cue was built on. Rapid, human-induced environmental change alters the ground faster than selection or learning can track, so the correlation between the cue and the quality is decoupled, the feature the cue reads no longer delivering the fitness it once did (Schlaepfer, on human-induced rapid environmental change decoupling cue from quality). The cue does not change, the ground under it does, and nobody who changed it meant the animal any harm. And the cue goes on reporting good over ground gone bad. Because the signal still fires exactly as before, the poor site still shows every mark of quality the chooser is built to read, so the apparent fit stays high while the true quality has fallen, the metric intact and the thing it measured gone (Robertson and Hutto, on the attractive cue persisting after the quality it indicated has dropped). The place still looks right by the only reading the animal has. And the chooser prefers the poor site, in a hard case over the good. Given a cue that still fires, the animal settles where it is strongest, and where the altered site fires the cue harder than the true habitat, the animal prefers the sink over the source, an equal-preference trap where good and bad look alike and a severe trap where the bad is chosen first (Robertson and Hutto, on the mechanisms of the trap, the attractive low-quality site preferred even above the high). So the good ground can stand empty while the sink fills, the choice faithful and the outcome inverted. And the preferred site draws the population below replacement. The settlers do everything right and still fail, nests mown, eggs on asphalt, young unfed, the site taking in more than it returns, an attractive sink pulling animals to below-replacement fitness by the very draw of its cue (Battin, on good animals loving bad habitats, the attractive sink a population is drawn into faster than it can leave), the classic case a gull colony leading ducks to nest where the ducks fare worst (Dwernychuk and Boag, on the empirical trap in the field). The stronger the draw, the deeper the loss. None of it is a lie or an error. The cue reported what it always reported, the people changed their own ground for their own reasons, and the animal read the sign the way the sign had earned, so no one deceived and no one erred and the sink filled anyway. What made the cue trustworthy, that it tracked quality for so long, is exactly what makes it dangerous once the tracking breaks, and a signal still firing is heard as a promise still kept. Realign the cue and the quality, and the trap can be dampened: restore the ground so the cue again tracks quality, or remove or dull the cue so it no longer fires over the sink, or buy the lineage time to re-learn what to read, and the sink can empty and the source fill: but this means finding every altered ground where an honest-looking cue now sits over poor quality, changing land or signal against no visible failure because the site still looks right and the animals still choose it willingly, and holding the fix as new change lays new traps under the same old cues, so the ground is realigned only by paying, without end, the cost of correcting a signal no one controls and a choice no one made wrongly.
Stakes
Whether a chooser can settle well, when it can only read the cue and the cue no longer tracks the ground. Every plot but the last moves the same way: toward the cue read and the site settled, which the animal is right to trust and the people right to alter, and away from the quality realigned, which would ask someone to change ground or signal against a site that still looks right and animals that still choose it. The production cannot make the cue tell the truth again on its own, because the cue tracks a feature and not the fitness, and a feature humans can change faster than a lineage can re-learn is a feature that will keep firing over ground that has gone bad, so the sink fills by adaptive choice and not by error: no one lied and every reading was earned. It can only show that the cue reported what it always reported and the ground was changed for reasons that had nothing to do with the animal and the chooser read the sign the way the sign had earned, that a strong cue over poor ground draws settlers below the rate at which they replace themselves while the true source stands empty for want of a cue, and that the one move that realigns cue and quality, restoring the ground or dulling the signal or buying time to re-learn, must be made by paying, continuously, the cost of correcting against a site that still looks right, so the animal chooses well and the ground is faithful to its cue and the place it fills is the one place that cannot keep it.
