“Home alone!” influence of nest parental attendance on offspring behavioral and hormonal stress responses in an Antarctic seabird, the snow petrel (Pagodroma nivea).
International audience In altricial species, parents brood their chicks constantly before leaving them unattended sometimes for extendedperiods when they become thermally independent. During this second phase, there is sometimes important interindividualdifferences in parental attendance and the fit...
