The gadwall (Mareca strepera) is a common and widespread dabbling duck in the family Anatidae. The gadwall was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae. DNA studies have shown that it is a sister species with the falcated duck; the two are closely related to the three species of wigeons, and all of them have been assigned to the genus Mareca. There are two subspecies:
Mareca strepera strepera (formerly Anas strepera strepera), the common gadwall, described by Linnaeus, is the nominate subspecies. The specific name strepera is Late Latin for "noisy". The etymology of the word gadwall is not known, but the name has been in use since 1666.
The gadwall is 47–58 cm (19–23 in) long with a 78–85 cm (31–33 in) wingspan. The male is slightly larger than the female, weighing on average 990 g (35 oz) against her 850 g (30 oz). The breeding male is patterned grey, with a black rear end, light chestnut wings, and a brilliant white speculum, obvious in flight or at rest. In non... Wikipedia →

Rare
Under 5% of wildlife watchers report a Gadwall sighting in Antalya on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 117th most-seen of the 131 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
October
In that month about 10% of wildlife watchers report a Gadwall in Antalya on a given day, against under 5% in November to September, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Gadwall sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
105th of 120
Of the 120 cities where we can rate Gadwall sightings, Antalya ranks 105th at under 5%. The best odds are in Anchorage (United States, about 50%), London (United Kingdom, about 30%) and Rotterdam [The Hague] (Netherlands, about 30%).
Same family: Anatidae
The closest relatives of the Gadwall that you can see in Antalya (family Anatidae, Ducks, Geese, and Swans) are Muscovy Duck (about 30%), Eurasian Teal (about 10%) and Garganey (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gadwall is recorded against all the birds logged in Antalya (6 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.
