The common sandpiper (Actitis hypoleucos) is a small Palearctic wader. This bird and its American sister species, the spotted sandpiper (A. macularia), make up the genus Actitis. They are parapatric and replace each other geographically; stray birds of either species may settle down with breeders of the other and hybridize. Hybridization has also been reported between the common sandpiper and the green sandpiper, a member of the closely related genus Tringa.
The common sandpiper was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his Systema Naturae under the binomial name Tringa hypoleucos. The species is now placed together with the spotted sandpiper in the genus Actitis that was introduced in 1811 by the German zoologist Johann Karl Wilhelm Illiger. The genus name Actitis is from Ancient Greek aktites meaning "coast-dweller" from akte meaning "coast". The specific epithet hypoleucos combines the Ancient Greek hupo meaning "beneath" with leukos meaning "white". The species is monotypic and no subspecies are recognised.
The adult is 18–20 cm (7.1–7.9 in) long with a 32–35 cm (13–14 in) wingspan. It has greyish... Wikipedia →

With luck
About 10% of wildlife watchers report a Common Sandpiper sighting in Freetown on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 30th most-seen of the 79 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January
In that month about 20% of wildlife watchers report a Common Sandpiper in Freetown on a given day, against under 5% in May, the lowest month. That is one of Freetown's driest months, with almost no rain against 700 mm in August. March–April, July–August and October–November have too few records to rate.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Common Sandpiper sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
84th of 202
Of the 202 cities where we can rate Common Sandpiper sightings, Freetown ranks 84th at about 10%. The best odds are in Zanzibar City (Tanzania, about 70%), Naha (Japan, about 60%) and Đà Nẵng (Vietnam, about 50%).
Same family: Scolopacidae
The closest relatives of the Common Sandpiper that you can see in Freetown (family Scolopacidae, Sandpipers and Allies) are Whimbrel (about 10%) and Common Greenshank (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Sandpiper is recorded against all the birds logged in Freetown (11 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.
