The black-legged kittiwake (Rissa tridactyla) is a seabird species in the gull family Laridae. This species was first described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae as Larus tridactylus. The English name is derived from its call, a shrill 'kittee-wa-aaake, kitte-wa-aaake'. In North America, this species is known as the black-legged kittiwake to differentiate it from the red-legged kittiwake, but in Europe, where it is the only member of the genus, it is often known just as kittiwake.
The black-legged kittiwake was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his Systema Naturae. He placed with the gulls in the genus Larus and coined the binomial name Larus tridactylus. Linnaeus specified the type location as northern Europe but this has been restricted to Great Britain. The black-legged kittiwake is now placed together with the red-legged kittiwake in the genus Rissa that was introduced in 1826 by the English naturalist James Stephens. The genus name is from the Icelandic word "rita" for a black-legged kittiwake. The specific tridactyla is from Ancient Greek tridaktulos meaning "three-toed... Wikipedia →

Rare
Under 5% of wildlife watchers report a Black-legged Kittiwake sighting in Montreal on a given day, based on 56 verified sightings from GBIF citizen-science data. It is the 226th most-seen of the 256 birds we can rate there. Over three days the chance rises to under 5%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Black-legged Kittiwake in Montreal on a given day, so our monthly data shows no clear season.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Black-legged Kittiwake sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
11th of 15
Of the 15 cities where we can rate Black-legged Kittiwake sightings, Montreal ranks 11th at under 5%. The best odds are in Dublin (Ireland, about 10%), Rotterdam [The Hague] (Netherlands, under 5%) and Liverpool (United Kingdom, under 5%).
Same family: Laridae
The closest relatives of the Black-legged Kittiwake that you can see in Montreal (family Laridae, Gulls, Terns, and Skimmers) are Ring-billed Gull (about 70%), American Herring Gull (about 20%) and Great Black-backed Gull (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Black-legged Kittiwake is recorded against all the birds logged in Montreal (56 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.
