Individual migration strategy fidelity but no habitat specialization in two congeneric seabirds
International audience Aim: In migratory species, individuals often use fixed and individual-specific migra-tion strategies, which we term individual migration strategy fidelity (IMSF). Our goal was to test if guillemots have flexible or fixed individual migration strategies (i.e. IMSF), if this beh...

In the context of rapidly changing environments, favourable habitats may permanently shift locations and hence species displaying IMSF driven by site familiarity—such as the genus Uria—may not be able to adjust their migration strategies sufficiently fast to sustain individual fitness and ensure population persistence.
