Fig. 3: Cumulative snow experienced during migration decreases with age.

a Total cumulative snow exposure experienced by conspecific-trained (hand- and parent-reared) birds during autumn and spring migrations by age (n = 242 migrations). Line and shading provide linear regression estimate and 95% confidence interval. b Cumulative snow experienced by three individuals ages 1, 2, and 3 years during spring migration in the year 2018. c Cumulative snow experienced by a single individual during spring migration as it aged from 1 to 5 years old.
