The Manx shearwater (Puffinus puffinus) is a medium-sized shearwater in the seabird family Procellariidae. The scientific name of this species records a name shift: Manx shearwaters were called Manks puffins in the 17th century. Puffin is an Anglo-Norman word (Middle English pophyn) for the cured carcasses of nestling shearwaters. The Atlantic puffin acquired the name much later, possibly because of its similar nesting habits.
The shearwaters form part of the family Procellariidae, a widespread group containing nearly 100 species of medium to large seabirds. They have long, narrow wings and the characteristic "tube nose". Although it was considered a monotypic species, recently an endemic subspecies for the Canary Islands has been proposed P. puffinus canariensis. The large genus Puffinus includes several species formerly considered to be subspecies of the Manx shearwater, including the yelkouan shearwater, Balearic shearwater, Hutton's shearwater, black-vented shearwater, fluttering shearwater, Townsend's shearwater and the Hawaiian shearwater. Of these, the Hawaiian and possibly Townsend's shearwaters seem to be most closely related to the Manx shearwater.

Rare
Under 5% of wildlife watchers report a Manx Shearwater sighting in Boston on a given day, based on 341 verified sightings from GBIF citizen-science data. It is the 187th most-seen of the 283 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 Manx Shearwater in Boston on a given day, so our monthly data shows no clear season.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Manx Shearwater sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
3rd of 4
Of the 4 cities where we can rate Manx Shearwater sightings, Boston ranks 3rd at under 5%. The best odds are in Dakar (Senegal, about 20%) and Dublin (Ireland, under 5%).
GBIF citizen-science records
It is estimated from how often the Manx Shearwater is recorded against all the birds logged in Boston (341 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.
