The introduction of mammal predators such as feral cats, rats, mongooses and even mice can have disastrous results for ecologically naïve seabirds.

There is no historical evidence of boom and bust cycles causing even local extinctions in regions where large mammal predators have been driven extinct by hunting.

No mammal predators for millennia-a heaven of birds, of countless species.

New Zealand has a high proportion of ground-nesting and flightless birds, due to the long geographical isolation and a lack of mammal predators.

Vultures rarely kill their own food, but are known for tidying up after the kills of bigger mammal predators such as of lions.

These wild canines are among the few mammal predators that can live in urbanized areas.

Dense swarms may elicit a feeding frenzy among fish, birds and mammal predators, especially near the surface.

It is also among the first mammal predators to prey on other mammals.

Historically, large game species were vulnerable to hunting and poaching, while other species, such as large mammal predators were vulnerable to habitat conversion to agriculture, leading to local extinction and numerous threatened species.

This can actually reduce the "revenge killing" of large mammal predators that has been a large cause of the population reductions.
