Alle alle

The little auk (Europe) or dovekie is a small auk, the only member of the genus Alle. It breeds in huge numbers on islands in the high Arctic of the North Atlantic Ocean. There are two subspecies; A. a. alle breeds in Greenland, Novaya Zemlya and Svalbard; and A. a. polaris on Franz Josef Land. A small number of individuals also breed on Little Diomede Island in the Bering Strait, with additional breeding individuals thought to occur on King Island, St. Lawrence Island, St. Matthew Island and the Pribilof Islands in the Bering Sea. It also formerly bred on Grímsey just north of Iceland, but is extinct there now. In winter, they disperse widely across the Arctic and North Atlantic Oceans, with the largest numbers in the Arctic close to the pack ice edge, and smaller numbers south to northern Great Britain in the eastern Atlantic, and Nova Scotia in the western Atlantic.

23 occurrences of Alle alle on record, most of them in the Pleistocene. The Paleobiology Database records this as a living group. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.

When

23 occurrences

These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

136 taxa

The Paleobiology Database records 21 sites for Alle alle, and this reads all of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.

This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.

Entered from

10 references

Each of the 23 occurrences read was entered from one of these publications, ordered by how many each accounts for. This is not a search for papers mentioning the name. Entries link to doi.org where the Paleobiology Database holds an identifier, and to its own record where it does not. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
