The black-winged stilt (Himantopus himantopus) is a widely distributed, very long-legged wader in the avocet and stilt family Recurvirostridae. Its scientific name, Himantopus himantopus, is sometimes used to generalize a single, almost cosmopolitan species. Alternatively, it is restricted to the form that is widespread in Europe, Asia and Africa, which equals the nominate group of H. himantopus sensu lato. Meanwhile, the black-necked (H. mexicanus) and white-backed stilts (H. melanurus) both inhabit the Americas; the pied stilt (H. leucocephalus) ranges from Australia and New Zealand. Today, most sources accept between one and four actual species.
The black-winged stilt was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. He placed it with the plovers in the genus Charadrius and coined the binomial name Charadrius himantopus. He specified the type locality as southern Europe. The taxonomic name Himantopus comes from Greek, meaning "strap-foot" or "thong-foot". The black-winged stilt is now one of five species placed in the genus Himantopus that was introduced by the French naturalist Mathurin Jacques Brisson... Wikipedia →
Rare
Under 5% of wildlife watchers report a Black-winged Stilt sighting in Osaka on a given day, based on 124 verified sightings from GBIF citizen-science data. It is the 83rd most-seen of the 180 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
October and December
In those months about 10% of wildlife watchers report a Black-winged Stilt in Osaka on a given day, against under 5% in January–September and November, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Black-winged Stilt sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
102nd of 126
Of the 126 cities where we can rate Black-winged Stilt sightings, Osaka ranks 102nd at under 5%. The best odds are in Quanzhou (China, about 70%), Agra (India, about 70%) and Kota (India, about 60%).
Same order: Charadriiformes
The closest relatives of the Black-winged Stilt that you can see in Osaka (order Charadriiformes, Shorebirds and Allies) are Common Sandpiper (about 20%), Black-headed Gull (about 10%) and Grey-headed Lapwing (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-winged Stilt is recorded against all the birds logged in Osaka (124 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.
