Porphyrio mcnabi

The Huahine swamphen is an extinct species of bird in the family Rallidae. It was a small swamphen endemic to Huahine in the Society Islands of French Polynesia. It is known only from subfossil remains found at the Fa'ahia archaeological site on the island. Fa'ahia is an early Polynesian occupation site with radiocarbon dates ranging from 700 CE to 1200 CE. The swamphen is only one of a suite of birds found at the site which became extinct either locally or globally following human occupation of the island.

No picture of Porphyrio mcnabi was found. Wikipedia, Wikidata and iDigBio were searched and had none. Smithsonian Open Access did not answer, so this is what the others held rather than everything there is. GBIF was asked, and what came back is not recorded: nothing, or a picture this site could not tie to Porphyrio mcnabi, or no answer at all. This entry cannot say which.

Time the record covers

At most 12 thousand years on record.

The one occurrence read is dated to somewhere between 11.7 ka and 0 Mya, which is a dating window rather than a span.

Pleistocene — about 0 of 1 occurrenceHolocene — about 1 of 1 occurrence17 ka–0 Mya — about 1 occurrence512 ka0 Mya

1 occurrence of Porphyrio mcnabi on record, most of them in the Holocene. 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

1 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.

The Paleobiology Database records 1 site for Porphyrio mcnabi, 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.
