The Hudsonian whimbrel or Hudsonian curlew (Numenius hudsonicus) is a wader in the large family Scolopacidae. It is one of the most widespread of the curlews, breeding across much of subarctic North America. This species and the Eurasian whimbrel were split in 2019 based on genetic and morphological differences and separate breeding ranges.
Two subspecies are recognized: Numenius hudsonicus rufiventris – Vigors, 1829: breeds in Alaska and northwestern Canada Numenius hudsonicus hudsonicus – Latham, 1790: (Hudsonian curlew) breeds in Hudson Bay area to northeastern Canada This is a fairly large wader, though mid-sized as a member of the curlew genus. The English name is imitative of the bird's call. The genus name Numenius is from Ancient Greek noumenios, a bird mentioned by Hesychius. It is associated with the curlews because it appears to be derived from neos, "new" and mene, "moon", referring to the crescent-shaped bill.
It is 37–47 cm (15–19 in) in length, 75–90 cm (30–35 in) in wingspan, and 270–493 g (9.5–17.4 oz; 0.595–1.087 lb) in weight. It is mainly greyish brown, with a rump pattern uniform with upperparts, and a long curved... Wikipedia →

Rare
Under 5% of wildlife watchers report a Hudsonian Whimbrel sighting in Vancouver on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 113th most-seen of the 252 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Hudsonian Whimbrel in Vancouver on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Hudsonian Whimbrel sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
14th of 15
Of the 15 cities where we can rate Hudsonian Whimbrel sightings, Vancouver ranks 14th at under 5%. The best odds are in São Luís (Brazil, about 30%), Panama City (Panama, about 30%) and San Diego (United States, about 30%).
GBIF citizen-science records
It is estimated from how often the Hudsonian Whimbrel is recorded against all the birds logged in Vancouver (8 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.
