Communal nests 1 The monk is the only parakeet that builds nests, rather than breeding in tree or rock cavities. As social , they breed in large multifamily stick nests, whereby each chamber is inhabited by a family group. The nests are Monk Parakeet used year-round, either for breeding Facts about the monk parakeet | monachus (Boddaert, 1783) or for roosting.

The monk parakeet, also called the Quaker , And not only in trees originates from . Adults are about the size of 2 Monk also build nests a blackbird, approximately 30cm. This small parakeet has a on man-made structures such as power pylons, potentially damaging distinctive grey breast, a grey throat and forehead, and a them. For example, in the USA, yellow-brown beak. The wings are green with blue in the monk parakeet nests on electricity flight feathers, and birds have a stiff, relatively long and poles often catch fire, causing costly power outages. pointed tail. Where do invasive monk An exotic in our towns and cities 3 parakeets come from? The monk parakeet is a popular cage bird worldwide. Over time, pet Monk parakeets from across birds have escaped or have been deliberately released by their Latin America have been exported owners, and growing populations of parakeets have successfully worldwide, yet genetic data show established across many parts of . The diet of monk parakeets that invasive populations exhibit low levels of diversity and are similar to includes seeds and fruits but they occasionally prey on small each other. Invasive monk parakeets invertebrates too. Monk parakeets can often be seen foraging on the may thus originate from a single, ground, squabbling with local pigeons for seeds or pieces of bread. localized source area.

Why might the presence of this species outside its A complex social behaviour native range be a problem? 4 Monk parakeets live in groups and young birds stay with their Invasions of non-native species are a major threat to biodiversity and parents until the next breeding cause many economic losses worldwide. Monk parakeets have been season. Some of the young parakeets reported to forage on crops in their native range, and in the areas start breeding the year after birth where they have invaded, their bulky stick nests can cause damage to while the others form temporary social groups, huddling together in a human infrastructures. In Europe, monk parakeets damage is chamber of the communal nest. currently only reported from the agricultural metropolitan area of Sometimes, several females seem to , where the parakeets forage upon corn, pears, plums, share a nest, breeding cooperatively persimmons and tomatoes. Yet, if populations keep growing and but this behaviour is probably not expand outside their urban strongholds, these parakeets may pose a too common. Monk parakeet social life is governed by a highly complex non-negligible threat to . set of behavioural rules.

Invasive monk parakeet populations have been recorded in many European countries, including Austria, , , the Netherlands, , , and the UK, as well as in North In Europe, predators such as America, and parts of Asia and Africa. sparrowhawks occasionally hunt These parakeets are well adapted to monk parakeets.

A global distribution 1 The ring-necked parakeet is the most widely distributed parakeet in the world. Outside of their substantial native range, they are established in over 35 countries, over five RING-NECKED PARAKEET continents!
