Birds together with kelp gulls, penguins, and southern big petrels can decide up micro organism corresponding to Salmonella and Campylobacter. After testing fecal samples of greater than 600 seabirds from a number of totally different places, three findings suggesting reverse zoonosis have been discovered.

The parrot was plentiful till the primary human settlers arrived and hunted them for feathers and meat. Land clearance and different predators—resembling home cats, canine, and stoats—virtually drove kakapos to extinction. The primary conservation efforts started in 1894, however they have been unsuccessful till the kakapo breeding program established in 1995.
There have been solely 51 kakapos left when this system started, however their inhabitants has elevated considerably since then. In response to the New Zealand Division of Conservation, there are 148 kakapos alive proper now.
