The common redshank or simply redshank (Tringa totanus) is a Eurasian wader in the large family Scolopacidae. The common redshank was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Scolopax totanus. It is now placed with twelve other species in the genus Tringa that Linnaeus had introduced in 1758. The genus name Tringa is the Neo-Latin name given to the green sandpiper by the Italian naturalist Ulisse Aldrovandi in 1603 based on Ancient Greek trungas, a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific totanus is from Tótano, the Italian name for this bird.

Rare
Under 5% of wildlife watchers report a Common Redshank sighting in Porto on a given day, based on 200 verified sightings from GBIF citizen-science data. It is the 77th most-seen of the 175 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
October
In that month about 20% of wildlife watchers report a Common Redshank in Porto on a given day, against under 5% in June and November–March, the lowest months. That is one of Porto's wettest months, with about 140 mm of rain against 15 mm in July.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Common Redshank sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
35th of 74
Of the 74 cities where we can rate Common Redshank sightings, Porto ranks 35th at under 5%. The best odds are in Naha (Japan, about 50%), Liverpool (United Kingdom, about 50%) and Manama (Bahrain, about 40%).
GBIF citizen-science records
It is estimated from how often the Common Redshank is recorded against all the birds logged in Porto (200 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.
