Gerygone igata

The grey warbler, also known by its Māori name riroriro, is an insectivorous bird in the family Acanthizidae endemic to New Zealand. Internationally, ornithologists usually refer to it as the grey gerygone or New Zealand gerygone to avoid confusion with unrelated birds also known as warblers. It is also sometimes known as the rainbird. The specific name igata was given by French naturalists Jean René Constant Quoy and Joseph Paul Gaimard, who claimed that this was the local name among the Māori inhabitants of Tasman Bay; this was likely a misunderstanding as no iwi are known to have a name resembling "igata" for the bird. Its natural habitat is forests, but also tends to occupy lower vegetation habitats. These insectivorous birds feed on insects living in shrubs, and often feed on the wing. They are found throughout New Zealand, as well as offshore islands where shrub exists. They also flourish in suburban areas where there is vegetation present.

Time the record covers

At most 129 thousand years on record.

Every occurrence read is dated to somewhere between 129 ka and 0 Mya, and nothing in the dating separates them, so that window is what the record shows rather than a span.

6 occurrences of Gerygone igata 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

6 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.

76 taxa

The Paleobiology Database records 6 sites for Gerygone igata, 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.

2 references

Each of the 6 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.
