Table 2. Model selection table for variables explaining provisioning behavior in response to short-term traffic noise playback.

Model	K	AICc	ΔAICc	weight
Parent sex (+), treatment (+), trial (+), time within 10 m (+), treatment*trial (+)	7	460.46	0.00	0.42
Brood size (+), parent sex (+), treatment (+), trial (+), time within 10 m (+), treatment*trial (+)	8	461.62	1.16	0.23
Parent sex (+), trial (+), time within 10 m (+)	5	462.41	1.95	0.16
Null	2	467.27	6.81	0.00

Note:

Time within 10 m was centered and scaled. +/− shows the direction of the trends. Bolded values show parameters with 95% CIs that do not overlap zero.
