Intraspecific variability in isotopic composition of a monomorphic seabird, the Common Tern (Sterna hirundo), at wintering grounds

Stable isotopes demonstrate intraspecific variation in habitat use and trophic level of non‐breeding albatrosses

“…Lamacchia et al . 2019). Less attention, however, has been paid to changes in foraging behaviour and distribution with age, despite some evidence that it may be an important driver (Phillips et al .…”

“…The degree of segregation in foraging ecology may be a function of sexual size dimorphism (SSD; Phillips et al 2011), although this appears to apply more to high-latitude than to tropical species (Mancini et al 2013), and studies have also demonstrated sex-related foraging strategies in species with reduced SSD (e.g. Lamacchia et al 2019). Less attention, however, has been paid to changes in foraging behaviour and distribution with age, despite some evidence that it may be an important driver .…”
