The Kiwi bird is in the kingdom Animalia, due to being eukaryotic, multicellular, heterotrophic, lacking rigid cell walls, and reproducing sexually. The kiwi bird is limited abiotically by geophraphical space, since they only live in the wild in New Zealand, and pollution also harms the kiwi bird. They are limited biotically by predation from introduced predators such as the cat, and deforestation from humans kills the kiwi bird. The Kiwi bird has suffered greatly because of human activity. Humans have introduced predators that were otherwise unheard of to the kiwi population, and their adaptation of smaller wings has harmed them greatly because of this. Cats and dogs are top predators to the kiwi bird and are even threatening the kiwi bird's existence. Those animals find their way into the kiwi's habitat and the kiwi bird is defenseless to saving itself. Kiwi birds have also been affected by deforestation caused by humans. Humans have reduced native forests in New Zealand from 85% of the land to 23% of the land. The kiwi bird has resorted to living in areas it isn't accustomed to, and is less likely to survive in those areas because of it.
The Kiwi bird is very isolated, and only experiences parasitism in symbiotic relationships. The Malaria parasite harms the kiwi for it's benefit.
The kiwi bird has the innate behaviors of being nocturnal, and mating for life. Being nocturnal allows the kiwi bird to hide during the day and find food at night. They also only mate with one partner, having a monogamous relationship with them.
