Alloparental care, where foster parents feed or defend foreign nestlings, has been reported in many bird species (Riedman 1982). This seemingly altruistic behaviour does not show a uniform pattern among bird groups, and has different interpretations according to when the adoption takes place, and whether the young are precocial, semiprecocial or altricial (e.g. Pierrotti 1991, Choudhury et al . 1993, Redondo et al . 1995, Brown 1998).
