摘要

Monk Parakeets (Myiopsitta monachus) build conspicuous, enclosed stick nests, which are often large and which have several isolated chambers (Forshaw 1978, Martella and Bucher 1993). These chambers are occupied throughout the year by breeding pairs and non-breeding individuals (Martin 1989, Martella and Bucher 1993). The Monk Parakeet is iteroparous, monogamous, and breeds in the spring and summer (October to February) (Navarro et al. 1992). Although all members of a compound nest participate in the building, maintenance, and vigilance of the nest, only the breeding pair cares for the nestlings (Martella 1985, Martella and Bucher 1993). Few cases of allofeeding by members of different nests have been observed, which could function for the development of a communal breeding system (Martella 1985, Bucher et al. 1991).
