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 Sacramento on a given day, based on 382 verified sightings from GBIF citizen-science data. It is the 122nd most-seen of the 235 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
February
In that month about 10% of wildlife watchers report an American Avocet in Sacramento on a given day, against under 5% in March to January, the lowest months. That is one of Sacramento's wettest months, with about 95 mm of rain against almost none in July.
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.
10th of 23
Of the 23 cities where we can rate American Avocet sightings, Sacramento ranks 10th at under 5%. The best odds are in León (México, about 30%), Mesa (United States, about 30%) and San Francisco (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the American Avocet is recorded against all the birds logged in Sacramento (382 verified sightings), 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.
