Stoats are a serious threat to ground- and hole-nesting birds, since the latter have very few means of escaping predation. The highest rates of stoat predation occur after seasonal gluts in southern beechmast (beechnuts), which enable the reproduction of rodents on which stoats also feed, enabling stoats to increase their own numbers. [ 32 ]
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.

In certain biotopes, birds constitute the bulk of the diet of various carnivorans, e.g., of adult leopard seals that mostly prey on penguins, the Arctic fox living in coastal areas where colonies of murres, auks, gulls and other seabirds abound and stoats in New Zealand against whom flightless birds like the takahē and kiwi are defenseless.
They eat the ortolan whole, with or without the head, and some may spit out the larger bones, while others eat the whole bird head, bones and all. The traditional way French gourmands eat ortolans is to cover their heads and face with a large napkin or towel while consuming the bird. The purpose of the towel is debated.
A bloodied but determined honey badger pursues a Cape porcupine in Botswana. After a quick retreat to lick its wounds, the badger returned to finish the job and dragged the porcupine back to its den.
The first illustration of the South Island takahē from Gideon and Walter Mantell's notice of the discovery in 1850. Anatomist Richard Owen was sent fossil bird bones found in 1847 in South Taranaki on the North Island by collector Walter Mantell, and in 1848 he coined the genus Notornis ("southern bird") for them, naming the new species Notornis mantelli.
