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 Portland on a given day, based on 1,009 verified sightings from GBIF citizen-science data. It is the 110th most-seen of the 230 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.
August
In that month about 20% of wildlife watchers report a Long-billed Dowitcher in Portland on a given day, against under 5% in November to June, the lowest months. That is one of Portland's driest months, with about 20 mm of rain against 250 mm in December.
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.
9th of 28
Of the 28 cities where we can rate Long-billed Dowitcher sightings, Portland ranks 9th at under 5%. The best odds are in Mesa (United States, about 30%), León (México, about 20%) and San Luis Potosí (México, about 10%).
GBIF citizen-science records
It is estimated from how often the Long-billed Dowitcher is recorded against all the birds logged in Portland (1,009 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.
