Buteo solitarius

The Hawaiian hawk or ʻio is a raptor in the genus Buteo endemic to Hawaiʻi, currently restricted to the Big Island. The ʻio is one of two extant birds of prey that are native to Hawaiʻi, the other being the pueo and fossil evidence indicates that it inhabited the island of Hawaiʻi, Molokaʻi, Oʻahu, Maui and Kauaʻi at one time. Today, it is known to breed only on the Big Island, in stands of native ʻōhiʻa lehua trees. The species was protected as an endangered species in the United States, but was delisted in 2020. However, the IUCN classifies the species as Near Threatened. NatureServe considers the species Vulnerable.

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 Buteo solitarius 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

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.

11 taxa

The Paleobiology Database records 1 site for Buteo solitarius, 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 1 occurrence 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.
