Charadrius sanctaehelenae

The Saint Helena plover, locally known as the wirebird due to its thin legs, is a small wader endemic to the island of Saint Helena in the mid-Atlantic. The bird is similar in appearance to Kittlitz's plover and the Madagascar plover, but a little larger and an absence of chamois coloring. It is the national bird of St Helena and has been depicted on the country's coins. Populations in general have been declining. Threats include predation by cats, the introduction of the common myna, deforestation, off-road vehicle use, the Saint Helena Airport and a projected windfarm. As of 2021, the population had recovered to about 545 mature individuals, from a previous minimum of less than 200 in 2006; consequently, the species was downlisted to Vulnerable from its previous assessment of Critically Endangered.

Time the record covers

At most 12 thousand years on record.

Every occurrence read is dated to somewhere between 11.7 ka and 0 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

Pleistocene — about 0 of 3 occurrencesHolocene — about 3 of 3 occurrences17 ka–0 Mya — about 3 occurrences512 ka0 Mya

3 occurrences of Charadrius sanctaehelenae on record, most of them in the Holocene. 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

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.

16 taxa

The Paleobiology Database records 3 sites for Charadrius sanctaehelenae, and this reads all of them. The number is how many of those sites it was catalogued from too.

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

1 reference

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. Each entry links to doi.org. Relayed as the Paleobiology Database holds them, not checked against what they resolve to.
