Results of Cox regression models investigating the reaction time of egg rejection or retrieval by incorporating its occurrence and latency

Model	Response variable	Fixed effect	Coefficient	S.E.	Z	P
1	Rejection	Treatment	−0.137	0.322	−0.426	0.670
		Species	−1.080	0.352	−3.072	0.002**
2	Rejection	Group	2.221	0.754	2.947	0.003**
		Species	−1.289	0.573	−2.251	0.024*
3	Retrieval	Group	0.172	0.267	0.644	0.520
		Species	0.102	0.250	0.407	0.684

Mode 1: rejection of model egg, treatment: INC (inside nest cup) or ONC (outside nest cup), species: magpie-robin or shama; Model 2: egg rejection of ONC treatment, group: conspecific or model egg; Model 3: egg retrieval of ONC treatment.
