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 N'Djamena on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 46th most-seen of the 70 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.
April
In that month about 30% of wildlife watchers report a Common Sandpiper in N'Djamena on a given day, against about 10% in January–March, May, July and September, the lowest months. That is one of N'Djamena's driest months, with about 5 mm of rain against 190 mm in August. June, August and October–December 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.
82nd of 202
Of the 202 cities where we can rate Common Sandpiper sightings, N'Djamena ranks 82nd at about 10%. The best odds are in Zanzibar City (Tanzania, about 70%), Naha (Japan, about 60%) and Đà Nẵng (Vietnam, about 50%).

GBIF citizen-science records
It is estimated from how often the Common Sandpiper is recorded against all the birds logged in N'Djamena (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.
