Abstract

Lay Summary Young and older animals of a kind often occur at different places. Such spatial segregation by age can emerge from individuals changing habitat as they get older, or from differential survival in different places, with those occupied by adults showing highest survival. Repeated observations of individually color-ringed red knots (a shorebird) showed that their increasingly offshore foraging distribution on the mudflats of Banc d’Arguin (Mauritania) is best explained by individual trajectories of change.Twitter: @vandenhoutpj
