- Geolocator was the primary variable of interest, but other variables were included (denoted by “X”) in species-specific GLMMs to control for potential confounding factors and identify subsets of the population that could be targeted to improve recovery rates of geolocators in future field studies.
-
aFor individuals with multiple nest attempts in 1 year, we used the fate of the final attempt as a potential explanatory variable of return rate
-
bWhether the current capture record is a recapture of an individual that was previously marked at the capture site
-
cTotal mass of color markers and metal band applied to each individual, not including the geolocator or attachment
