Extreme migration and the individual quality spectrum
Costs of migration, in terms of time, energy, and mortality risk, have a strong theoretical and empirical foundation in the study of birds. We expect these costs to be most severe for extreme long-distance migratory landbirds, whose demanding annual routines (e.g. non-stop flights > 8000 km and r...

Costs of migration, in terms of time, energy, and mortality risk, have a strong theoretical and empirical foundation in the study of birds. We expect these costs to be most severe for extreme long-distance migratory landbirds, whose demanding annual routines (e.g. non-stop flights > 8000 km and return journeys > 30 000 km) may approach their maximum physiological capabilities. To explore whether this is true, we review evidence in long-jump migratory shorebirds (Scolopacidae), focusing most on the prototypical example, the Alaska-breeding bar-tailed godwit Limosa lapponica baueri. Contrary to expectations, these and similar birds demonstrate high adult survival, little evidence for elevated mortality during migration, no apparent minimisation of non-stop flight distances, and low inter- and intra-individual variation in migration performance. Two key aspects of extreme migrants may explain these findings: 1) a counter-intuitively conservative annual-cycle strategy, which minimises risks and enables dissipation of carry-over effects before fitness consequences arise; and 2) selection pressure during early life, which quickly removes low-performing individuals from the population. We hypothesise that these two factors, applicable to extreme strategies in a wide range of taxa, act to truncate the range of individual quality in a population, and decrease the prevalence and detectability of carry-over effects.
