The higher stoat numbers reduce the rodent population and the stoats then prey on birds. [6] For instance, the wild population of the endangered takahē dropped by a third between 2006 and 2007, after a stoat plague triggered by the 2005–2006 mast wiped out more than half the takahē in areas where stoat numbers were not limited by trapping.

Skull. The root word for "stoat" is likely either the Dutch word stout ("bold") [4] or the Gothic word 𐍃𐍄𐌰𐌿𐍄𐌰𐌽 (stautan, "to push"). [5] According to John Guillim, in his Display of Heraldrie, the word "ermine" is likely derived from Armenia, the nation where it was thought the species originated, [4] though other authors have linked it to the Norman French from the ...
Scarcity during colonial history may have been due to early spread of brown rats and feral cats throughout New Zealand; a captive bird showed alarm at the presence of a cat. Final extinction coincided with the first expansion of stoats on the West Coast Region, before the wetlands were drained for farming. [87]
The near extinction of the formerly widespread South Island takahē is due to a number of factors: over-hunting, loss of habitat and introduced predators have all played a part. The introduction of red deer (Cervus elaphus) represent a severe competition for food, while stoats (Mustela erminea) take a role as predators.

The reason of extinction is unknown, as New Caledonia is today home to two other Accipiter species, the brown goshawk and the white-bellied goshawk. However, the extinct and extant species not being found together could indicate that they lived in different habitats, or that the extant species colonized the island after the others disappeared.
