Extreme fattening by sedge warblers, Acrocephalus schoenobaenus, is not triggered by food availability alone
2007, Animal BehaviourCitation Excerpt :This assumption is broken by EX birds, in particular, whose FDR gradually decreases in the later stages of fuelling (see Figs 5 and 6). Rising metabolic demands associated with the maintenance and transport of an increasing fuel load are most probably the cause of this decrease (Klaassen & Lindström 1996). Reed warblers seem to compensate for similar rising energy demands by increasing their intake rate, which may otherwise be reduced to minimize foraging-intensity dependent predation risk (Bayly 2006).
