Using geolocators to track migration phenology

figure from Renfrew et al. (2013)

Kernel density estimates showing southward migration of bobolinks from Oregon, Nebraska, and Vermont. See Renfrew et al. (2013) for more detail.

Check out this new paper looking at the phenology of bobolink movements as they migrate south.

“We deployed light-level geolocators on individual Bobolinks from three populations across the breeding range and compare their southbound movement phenology to austral greening as indicated by the Normalized Difference Vegetation Index.”
