Use of a new model to quantify compromises between embryo development and parental self-maintenance in three species of intermittently incubating passerines

1.Instead of just times to cool (tcool) and heat (theat), intermittent incubation cycles contain a period (tequil) when eggs are kept at relatively high equilibrium temperatures after heating.2.Relative allocations favoring parental self-maintenance [when (tcool+theat)>tequil] versus embryo development [when (tcool+theat)
