Table 1. The division of sample age stage and bats’ morphological parameters and sampling number.

Ages were estimated using the age equations of Jin et al. (2012).

Age	Forearm length (mm)	Length of total gap (mm)	Definition of age period	Number of individuals
ca. day 1	15.69 ± 0.29	NA	Day 1	4
ca. days 6–9	23.30 ± 1.34	NA	Week 1	6
ca. days 13–15	30.57 ± 0.87	NA	Week 2	7
ca. days 19–22	30.68 ± 0.90	NA	Week 3	7
ca. day 28	47.73 ± 0.43	NA	Week 4	8
ca. days 35–38	NA	1.91 ± 0.37	Week 5	6
ca. days 41–44	NA	0.91 ± 0.26	Week 6	7

Note:

NA, the data were not used to assess individual bat age at that division. Length values shown are means ± SE.
