Where the name comes from

Recurvirostra means “bill bent backwards”, and it is an exact description of a tool that points up rather than down. Avosetta is Italian’s gift to science: it was the bird’s name in the Venetian lagoons, collected by sixteenth-century naturalists and adopted by Linnaeus as it stood.

What sets it apart

It had been gone from Britain for a century when, in 1947, a few pairs returned to nest on the Suffolk coast: during the war that ground had been deliberately flooded to hinder a German landing, and out of it had come exactly the brackish lagoons the species needed. The return was so remarkable that Britain’s principal bird society took the avocet as its emblem. It is a bird that came back thanks to an anti-invasion defence.
