Slender-billed curlew: first modern European bird extinction

The slender-billed curlew goes extinct: last sighting in 1995

The last time anyone saw a living slender-billed curlew was in 1995, at a wetland in Segarro where the species spent the winter. Since then, no confirmed sightings. The bird is officially extinct and enters the records as the first European species known to disappear in modern times. What is unsettling is not just the ending, but what, according to one of the debate participants, was never precisely established: where it bred.

By the early 20th century it was already a hard bird to observe and barely studied, which undermined any conservation effort from the start. The causes cited are the usual ones, piled up: disappearance of peat bogs and wetlands to agricultural use, illegal hunting, pesticide and herbicide pollution, climate change, and a scattered population that had shrunk since the turn of the century into very small groups with little breeding success. None alone explains the outcome; together they made it only a matter of time. The collage of factors is, in fact, the standard portrait of any extinction foretold.

Why did the slender-billed curlew disappear?

Habitat loss is listed as the main cause, but the file has an awkward gap. Some argue that its breeding habitat was never precisely established, and that attributing the disappearance to the sum of all known factors is, at the very least, a stretch. Central Asia is suggested as the nesting area, without conclusive proof. The species reached the 21st century with no census, no map and no plan.

Among the laments in hindsight, one recurring question stands out: why were no specimens kept in zoos when extinction had been looming for decades. The answer the case itself provides is uncomfortable, and would almost be laughable if it were not for the bird: to breed in captivity you need to know what it eats, where it nests and how it reproduces. Of this creature, not even that was known.

Was the slender-billed curlew a European bird?

Not everyone accepts the label. Some argue it was a species whose wintering was concentrated in North Africa and whose breeding grounds lay outside the continent, so presenting it as an "extinct European bird" would be a misuse of language. The starting point of the debate, however, counts it among European birds and places it as the first species of the continent to go extinct in modern times. The nuance matters more than it seems, because it determines how the blame is apportioned.

The Eurasian curlew survives, but is under threat

From the same family, another European member survives: the Eurasian curlew, classified as endangered. It is a reminder that this is not a statistical anomaly: it is a trend. The wetlands drained for agriculture have not recovered, and pressure on wading birds has not eased. The news also served as an umbrella for after-dinner remarks about the disappearance of languages, cultures and the European population, a leap no ornithologist endorses and one that fixes neither census.

The file closes with an oddity: a species declared extinct whose breeding grounds remain a mystery. The light goes out and the question remains. For once, when science was supposed to certify an ending, it does not even know where it began.
