Migratory connectivity of western (W), southern (S) and eastern (E) breeding populations of common nightingales (see Hahn et al. 2013 for more detail).
A new publication in the journal Behavioral Ecology uses geolocators to reveal migratory connectivity and stable isotopes to illuminate habitat niche. Check out how the authors use this synergy of methods to get a more complete understanding of ecology throughout the annual cycle.
