The American avocet (Recurvirostra americana) is a large wader in the avocet and stilt family, Recurvirostridae, found in North America. It spends much of its time foraging in shallow water or on mud flats, often sweeping its bill from side to side in water as it seeks crustacean and insect prey.
The American avocet was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the pied avocet in the genus Recurvirostra and coined the binomial name Recurvirostra americana. Gmelin based his description on that by the English ornithologist John Latham who in 1785 had described and illustrated the American avocet in his A General Synopsis of Birds. Latham cited the earlier publication by William Dampier and also that by Thomas Pennant. The genus name combines the Latin recurvus meaning 'bent' or 'curved backwards' with rostrum meaning 'bill'. The species is monotypic: no subspecies are recognised.
The American avocet is a member of the order Charadriiformes, which includes shorebirds, gulls, and alcids. Its family, Recurvirostridae, includes stilts and avocets. The... Wikipedia →

Rare
Under 5% of wildlife watchers report an American Avocet sighting in Zion National Park on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 172nd most-seen of the 183 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report an American Avocet in Zion National Park on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most American Avocet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
15th of 17
Of the 17 parks where we can rate American Avocet sightings, Zion National Park ranks 15th at under 5%. The best odds are in Merritt Island National Wildlife Refuge (United States, about 20%), El Vizcaíno Biosphere Reserve (Mexico, about 20%) and Celestún Biosphere Reserve (Mexico, about 10%).
GBIF citizen-science records
It is estimated from how often the American Avocet is recorded against all the birds logged in Zion National Park (9 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
