Pallas's gull (Ichthyaetus ichthyaetus), also known as the great black-headed gull, is a large bird species. As is the case with many gulls, it has traditionally been placed in the genus Larus. The scientific name is from Ancient Greek. Ichthyaetus is from ikhthus, "fish", and aetos, "eagle".
This species breeds in colonies in marshes and islands from southern Russia to Mongolia. It is migratory, wintering in the eastern Mediterranean, Arabia and India. This gull nests on the ground, laying between two and four eggs.
It occurs in western Europe only as a vagrant. In Great Britain a recent review left a single occurrence in 1859 as the only acceptable record of this bird. The species also occurs as a vagrant in differing parts of the Indian Ocean, south of its normal range, and along the northern and eastern coasts of Africa, where it visits annually on an irregular basis.
This is a very large gull, being easily the world's largest black-headed gull and the third largest species of gull in the world, after the great black-backed gull and the glaucous gull. It measures 55–72 cm (22–28 in) in length with a 142 to 170 cm (56 to 67 in) wingspan. Weight... Wikipedia →

Rare
Under 5% of wildlife watchers report a Pallas's Gull sighting in Agra on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 103rd most-seen of the 119 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
January
In that month about 10% of wildlife watchers report a Pallas's Gull in Agra on a given day, against under 5% in February to December, the lowest months. That is one of Agra's driest months, with about 15 mm of rain against 190 mm in July.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Pallas's Gull sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
7th of 17
Of the 17 cities where we can rate Pallas's Gull sightings, Agra ranks 7th at under 5%. The best odds are in Lanzhou (China, about 40%), Novosibirsk (Russia, about 10%) and Kuwait City (Kuwait, about 10%).
Same family: Laridae
The closest relatives of the Pallas's Gull that you can see in Agra (family Laridae, Gulls, Terns, and Skimmers) are Black-headed Gull (about 10%), Whiskered Tern (about 10%) and River Tern (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Pallas's Gull is recorded against all the birds logged in Agra (14 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.
