Effect of parasite treatment on nestling provisioning and the proportion of time that the parents spent in box

Behavioral parameter	Eastern bluebird				Tree swallow
	Parasitized		Nonparasitized		Parasitized		Nonparasitized
	Day 5	Day 10	Day 5	Day 10	Day 5	Day 10	Day 5	Day 10
Nestling provisioning	0.27 ± 0.08 (5)	0.26 ± 0.06 (6)	0.18 ± 0.05 (4)	0.30 ± 0.07 (4)	0.41 ± 0.03 (10)	0.42 ± 0.04 (11)	0.37 ± 0.05 (7)	0.50 ± 0.08 (8)
Proportion of time in box	0.14 ± 0.06 (5)	0.11 ± 0.06 (6)	0.07 ± 0.01 (4)	0.14 ± 0.06 (4)	0.52 ± 0.09 (10)	0.25 ± 0.08 (11)	0.71 ± 0.05 (7)	0.19 ± 0.03 (8)

Proportion of time spent in the box was quantified from the total time observed. Nestling provisioning was quantified as number of feeding events per minute. Numbers are in mean ± SE and numbers in parentheses are the number of nests.
