Numenius borealis
The Eskimo curlew, also known as northern curlew, is a species of curlew in the family Scolopacidae. It was one of the most numerous shorebirds in the tundra of western Arctic Canada and Alaska. Thousands of birds were then killed per year in the late 1800s. As there has not been a reliable sighting since 1987 or a confirmed sighting since 1963, the Eskimo curlew is considered Critically Endangered or possibly extinct. The bird is about 30 cm (12 in) long and feeds mostly on insects and berries.

Time the record covers
At least 3.4 million years on record.
The record covers at least 3.6 Mya to 129 ka. No occurrence read is dated outside 5.333 Mya to 11.7 ka.
3 occurrences of Numenius borealis 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
3 occurrences- Pliocene33%
- Pleistocene67%
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.

The Paleobiology Database records 3 sites for Numenius borealis, 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.

Each of the 3 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.
