From: Effects of tag mass on the physiology and behaviour of common noctule bats

Seasonal variation in body masses of 747 male and 1265 female common noctule bats N. noctula from a colony in Northeast Germany. Box plots show adult bat body mass in a given month, coloured background shows pregnancy period. Rug plots on the y-axis show the distribution of individual body masses. Solid line curves indicate the predicted mean with grey area as 0.95 confidence interval from generalized additive mixed model; outliers excluded. No data were collected in January to avoid disturbance in the middle of hibernation
