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 →

Possible
About 20% of wildlife watchers report a Long-billed Curlew sighting in San Diego on a given day, based on 7,600 verified sightings from GBIF citizen-science data. It is the 49th most-seen of the 386 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
February
In that month about 30% of wildlife watchers report a Long-billed Curlew in San Diego on a given day, against about 10% in April to June, the lowest months. That is one of San Diego's wettest months, with about 55 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 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.
Yes
Of the 9 cities where we can rate Long-billed Curlew sightings, San Diego has the highest daily chance: about 20%. Next come San Francisco (United States, about 10%) and Tijuana (México, about 10%).
Same genus: Numenius
The closest relatives of the Long-billed Curlew that you can see in San Diego (genus Numenius, Curlews) are Hudsonian Whimbrel (about 30%) and 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 San Diego (7,600 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.
