Monk parakeets display several types of \"helping behaviours\" that may have contributed to their success as alien species. Included are communal nest building, delayed breeding, the presence of non-breeding mature adults, nest sentinel systems and reduced natal dispersal. After leaving the nest, young birds often remain close, building their own nests or adding on to an existing nest. Nests can be small, housing a single pair or up to one metre in diameter and weighing 200kg and house multiple pairs. Nests have roofs and entry holes, mainly on the underside and often multiple chambers for nesting pairs and small groups of non-breeding indivduals. (Spreyer and Bucher, 1998). \"Once the site of the nest structure is selected, individual monk parakeets construct a nest cavity, affixing it to the main nest structure.\" (Burger and Gochfeld, 2005). M. monachus are very social birds, having eleven or more different calls that each elicit a different response from others in the colony. (Campbell, 2000)
Studies of monk parakeet populations at Arroyito and Jesus Maria, Cordoba province, Argentina, showed that monk parakeets preferred Eucalyptus trees (Arroyito) and native trees (Jesus Naria) for breeding nests (Navarro, Martella, & Bucher, 1992). In its introduced range they live almost exclusively in urban areas, preferring open habitats, including parks, planted urban areas, golf courses, farms, gardens and orchards (Campbell, 2000).
