Avocet
Waders with upcurved bills, known for sweeping feeding.
Avocets are a genus, Recurvirostra, of waders in the same avian family as stilts. The genus name comes from Latin recurvus, 'curved backwards' and rostrum, 'bill'. The common name is thought to derive from the Italian (Ferrarese) word avosetta, which may relate to Latin avis ('bird').

Lore & Background
Avocets have long legs and long, thin, upcurved bills which they sweep from side to side when feeding in the brackish or saline wetlands they prefer. Their plumage is pied, sometimes also with some red. Members of this genus have webbed feet and readily swim. Their diet consists of aquatic insects and other small creatures. Avocets nest on the ground in loose colonies. In estuarine settings, they may feed on exposed bay muds or mudflats. The nest is simply a lining of grass in a hollow in the ground. They lay three or four eggs of a dark greenish or brownish buff color, boldly marked with brown and black.
Reader's Guide
Avocets are significant as a distinctive genus of waders, notable for their unique feeding method and pied plumage. The pied avocet serves as the emblem of the Royal Society for the Protection of Birds, highlighting its symbolic importance in conservation. Historically, avocets were extirpated in Britain due to land reclamation and persecution by collectors, but they reestablished breeding populations during or after World War II on reclaimed land near the Wash, which was returned to salt marsh to hinder potential German invaders. They also use Titchfield Haven National Nature Reserve as a summer breeding ground. In large colonies, they are aggressively defensive, chasing off other bird species, which has led to the remark 'Avocet: Exocet' from some British birdwatchers. The fossil record includes one species, R. sanctaneboulae, from the late Eocene of France, indicating the genus's ancient lineage.

Frequently Asked Questions
What is an Avocet?
Avocets are a small genus of wading birds (Recurvirostra) that sit in the same avian family as stilts. The genus contains four living species, all sharing a striking body plan of very long legs paired with a thin, upward-curved bill.
What are Avocets known for in the wild?
They are best recognized for their sweeping feeding technique, dragging the tip of their curved bill through shallow water or soft mud to pick out tiny invertebrates. That combination of long legs, a slender upcurved bill, and the lateral sweeping motion makes them easy to spot along coastal and wetland shores.
Where does the name 'Avocet' come from?
The genus name Recurvirostra is built from the Latin words for 'curved backwards' and 'bill,' a direct nod to the beak's shape. The everyday English name is thought to trace back to the Ferrarese Italian word 'avosetta,' which may itself echo the Latin 'avis,' simply meaning bird.
Is there a fossil record for Avocets?
Yes—the only known fossil species is R. sanctaneboulae, recovered from late Eocene deposits in France. It pushes the lineage of these waders back millions of years and shows that the upcurved-bill body plan was already established in the ancient past.
Why do Avocets matter to bird enthusiasts and ornithologists?
With just four species, they occupy a narrow but distinctive niche among shorebirds, making them a useful case study for how bill shape and foraging strategy co-evolve. Their close family ties to stilts also give researchers a natural comparison for tracking adaptive radiation in wading birds.
