The long-billed dowitcher (Limnodromus scolopaceus) is a medium-sized shorebird with a relatively long bill belonging to the sandpiper family, Scolopacidae. In breeding plumage, adults are characterized by a rufous head and underparts with a darker mottled back and a large white upper rump only seen in flight. They feed in various freshwater habitats with their bill underwater in a "sewing machine" motion and have a mating display where males chase females in flight. The genus, Limnodromus is Ancient Greek from limne, "marsh" and dromos, "racer". The specific scolopaceus is Neo-Latin for "snipe-like", from Latin scolopax, scolopacis, a snipe or woodcock. The English name is from Iroquois and was first recorded in 1841.
The long-billed dowitcher is similar in appearance to the short-billed dowitcher and was only recognized as a separate species in 1950. Between the two, the best distinguishing field mark is their flight call, especially in winter, when the two species' plumage can be nearly identical. However, the two species differ ecologically in their habitat preferences and breeding locations. Long-billed dowitchers generally prefer freshwater habitats, and breed in northern Alaska and Siberia; their short-billed counterparts favor saltwater habitats and breed farther east, from southern Alaska across Canada to the maritime provinces.

Rare
Under 5% of wildlife watchers report a Long-billed Dowitcher sighting in Tokyo on a given day, based on 80 verified sightings from GBIF citizen-science data. It is the 139th most-seen of the 229 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 a Long-billed Dowitcher in Tokyo on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Long-billed Dowitcher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
18th of 28
Of the 28 cities where we can rate Long-billed Dowitcher sightings, Tokyo ranks 18th at under 5%. The best odds are in Mesa (United States, about 30%), León (México, about 20%) and San Luis Potosí (México, about 10%).
Same family: Scolopacidae
The closest relatives of the Long-billed Dowitcher that you can see in Tokyo (family Scolopacidae, Sandpipers and Allies) are Common Sandpiper (about 20%) and Grey-tailed Tattler (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Long-billed Dowitcher is recorded against all the birds logged in Tokyo (80 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.
