What animal was the main predator of the Huia?

The main predator of the Huia, a bird native to New Zealand, was the introduced stoat (Mustela erminea). Stoats were brought to New Zealand in the 19th century to control rabbit populations but became a significant threat to native birds, including the Huia. Their predation, combined with habitat loss and other factors, contributed to the decline and eventual extinction of the Huia by the early 20th century.
