The table has now been corrected. TABLE 1. Summary of the typical differences between capital, intermediate and income migration Classification Income migration Intermediate strategy migration Capital migration Description Opportunistic feeding frequently interrupts travel Stopovers for refuelling Nonstop migration Diagnostic feature Mass stable Migration divided into two or more periods of fasted travel, punctuated by foraging interruptions Mass declines continuously throughout migration due to consumption of energy stores Typical travel mode All, but especially terrestrial Flying, swimming Flying, swimming Phenotypic flexibility Typically limited, although can be considerable in some aerial migrants, e.g. hoary bats (McGuire et al., 2013) Variable Extensive: coordinated reorganisation of morphological, physiological and behavioural phenotypes Pre-departure behavioural plasticity Negligible, although modest increases in fat stores are possible High: obligate hyperphagy High: obligate hyperphagy Adjustability of departure schedule High Medium: as for capital migrants, intermediate strategy migrants will undertake fasted journeys and likely rely on sites offering high but short-lived resource availability Low: morphological specialisation is a commitment to migration. Additionally, conditions on the arrival site may be stronger determinants of survival or reproductive success, and may be unrelated to conditions at the departure site Trigger for departure Departure occurs when conditions at nearby sites are superior to the current location Departure dependent on endogenous energy stores Departure dependent on endogenous energy stores Time between origin and destination Long Long Short Post-departure adjustability of travel schedule High: migration proceeds along the route in synchrony with a pulse in local resource availability (Aikens et al., 2020) Moderate: opportunistic interruptions for foraging are possible Low: migration insensitive to resource availability along the route Cost of foraging during migration Little different to foraging costs during sedentary phases of migration cycle High but stopovers for feeding are essential Very high: deviation from straight-line course; cost of reversing phenotypic specialisation; greatly extends duration of migration REFERENCES Aikens, E.
