It is the only parrot that builds communal stick nests; it is invasive in Madrid and Barcelona.
From Monk Parakeet
It is the only parrot in the world that builds a nest: its communal structures of twigs can reach the size of a small car, weigh more than two hundred kilos and house dozens of pairs in separate chambers.
From Monk Parakeet
Those nests also shelter other species: in South America they are occupied by ducks, falcons and opossums, and in Spanish cities they cause problems when their weight breaks the branches of street trees.
From Monk Parakeet
It is the most widely distributed parrot in the world, largely thanks to human beings: there are established urban colonies from London and Brussels to Tokyo, Tehran and Madrid.
From Rose-ringed Parakeet
It competes for nest holes with native species such as the greater noctule bat in Seville, and that conflict is one of the reasons for its inclusion on the Spanish catalogue of invasive alien species.
From Rose-ringed Parakeet
The Abaco subspecies, in the Bahamas, nests underground: it occupies cavities in the limestone ground instead of tree holes, the only parrot in the world that does so as a matter of course.
From Cuban Amazon
That underground nesting protects it from hurricanes but leaves it defenceless against feral cats, and cat control has been the decisive measure in its recovery on Abaco.
From Cuban Amazon
In Cuba it remains a traditional cage bird, and the taking of chicks from nests is the main cause of its decline on the island.
