Resumen:
Helping in the cooperative breeder Monk Parakeet (Myiopsitta monachus) consists of one adult15 helping the breeding pair (trios). We found a breeding trio composed of two males and one female16 in a single breeding chamber of a two-chamber compound nest. Males were full siblings. The17 female was half sibling of both males. The female and one male were genetic parents of all18 nestlings. The sampled parakeet population showed a higher than expected level of inbreeding. The19 Monk Parakeet provides an interesting model for the understanding of the role and benefits of20 helping and extra parental behavior in cooperative breeding birds.
