The long-billed curlew (Numenius americanus) is a large North American shorebird of the family Scolopacidae. This species was also called "sicklebird" and the "candlestick bird". The species breeds in central and western North America, migrating southward and coastward for the winter.
The long-billed curlew is the largest sandpiper of regular occurrence in North America. It is 50–65 cm (20–26 in) long, 62–90 cm (24+1⁄2–35+1⁄2 in) across the wing and weighs 490–950 g (1 lb 1+1⁄2 oz – 2 lb 1+1⁄2 oz). Its disproportionally long bill curves downward and measures 11.3–21.9 cm (4+1⁄2–8+5⁄8 in), and rivals the bill of the larger-bodied Far Eastern curlew as the longest bill of any shorebird. Individuals have a long neck and a small head. The neck and underparts are a light cinnamon in color, while the crown is streaked with brown. This species exhibits reversed sexual dimorphism, as in many sandpipers, the female being larger and having a much longer bill than the male's.
The breeding habitat is grasslands in west-central North America. The species displays an elaborate courtship dance, with fast and looping display flights also being common. A small hollow... Wikipedia →

Likely
About 40% of wildlife watchers report a Long-billed Curlew sighting in El Vizcaíno Biosphere Reserve on a given day, based on 512 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 237 birds we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
February
In that month about 60% of wildlife watchers report a Long-billed Curlew in El Vizcaíno Biosphere Reserve on a given day, against about 10% in May, the lowest month.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Long-billed Curlew sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 12
Of the 12 parks where we can rate Long-billed Curlew sightings, El Vizcaíno Biosphere Reserve ranks 2nd at about 40%. The best odds are in Padre Island National Seashore (United States, about 60%).
Same genus: Numenius
The closest relatives of the Long-billed Curlew that you can see in El Vizcaíno Biosphere Reserve (genus Numenius, Curlews) are Whimbrel (about 30%) and Hudsonian Whimbrel (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Long-billed Curlew is recorded against all the birds logged in El Vizcaíno Biosphere Reserve (512 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.
