Figure 1. Short-term changes in body mass of Golden-crowned Sparrows with and without geolocator tags.

The difference between initial capture and post-tagging (3–80 days) weights for Golden-crowned Sparrows with geolocator tags and metal and plastic leg bands (tagged; n = 10) and with metal and plastic leg bands only (control, n = 6). Box plots show the range (whiskers), interquatile range (box), median (horizontal line), and mean (dot) for each group. The average difference in pre- and post-tagging weights was not statistically significant (two-way repeated-measures ANOVA, interaction between tag attachment (yes/no) and capture time (before/after): F_1,15 = 0.0068, p = 0.94; Fig. 1).
