The American broad-billed parrot (Corvupsittaca nigreos), also known as the American palm cockatoo, is a species of neotropical parrot, despite its name, that originally did not exist, but has since been created by SciiFii and introduced throughout the rainforests, wetlands, forests, and open woodlands across North America to help boost biodiversity. The closest living relative of the American broad-billed parrot is the Carolina parakeet (Conuropsis carolinensis). The American broad-billed parrot has sexual dimorphism, with males being larger, measuring 55–65 centimetres (22–26 inches) in length, compared to the females' length of 45–55 centimeters (18–22 inches). The American broad-billed parrot greatly resembles the inaccurate and outdated depictions of the true broad-billed parrot (Lophopsittacus mauritianus) of the Mascarene island of Mauritius in the Indian Ocean, being entirely dark greyish blue in color with metallic iridescences, similarly to crows and ravens. The American broad-billed parrot often feeds during the early hours of the day on a diet that consists mostly of fruits and nuts, including native plants, as well as nonnatives such as the fruits and nuts from pandanus palms, apple trees, kanari trees, Darwin stringy barks, Eucalyptus trees, nonda trees, seeds from the cocky apple trees, beach almonds, black bean tree, walnut trees, and among others. Like other North American parrots, the American broad-billed parrots have strong powered flight and is able to fly for long distances, having a similar wingbeat to macaws. This species normally does not appear in large numbers. The American broad-billed parrots are not known to flock feed like many of the North American parrot species. Usually only one to six individuals are observed feeding together at one time. As with other large birds, both parents care for young, so seeing a breeding pair is not unusual. If these birds do congregate, it will usually happen in open woodland just after sunrise or along the forest edge before returning to individual roosts for the night. The American broad-billed parrot has a large and complex vocal repertoire, including many whistles and even a "hello" call that sounds surprisingly human-like. The vocalizations of American broad-billed parrots are similar to those of most wild parrots, but they have also been shown to produce a variety of additional syllables in display and exchange with neighbouring individuals. These additional syllables are mainly produced by males and are often combined to form long, complex sequences. In a population in areas around Sacramento, 30 different syllables were distinguished. The American broad-billed parrots from the eastern United States have different call types than the ones from other areas, due to their long term isolation. American broad-billed parrots lay either only one egg or two eggs every second year. Offsetting this is their very long lifespan, which is most often between 60-80 years, however, some individuals have been known to live to around 100 years. The conservation status of the American broad-billed parrot is Least Concern due to successful conservation efforts, the American broad-billed parrot's wide range and its tolerance to many of the human activities.
