Fuel Deposition Rate and Energy Efficiency of Stopovers

  • Nikita Chernetsov
Chapter

Abstract

In this chapter I review the methods of estimating the fuel deposition rate (FDR) of stopover migrants. These methods are based either on body mass change in the birds captured at least twice, or on body mass relationship with the time of day in single captures, or on analysis of metabolites in blood plasma. There is no perfect method; every approach has its benefits and pitfalls. The empirical values of the FDR reported in the literature are reviewed, and various factors that influence the FDR during migratory stopovers are discussed. Very often the FDR does not remain constant throughout stopover: it is low or even negative during 1–2 days after arrival but subsequently increases. It may also drop again towards the end of stopover. The ecological and behavioural causes and implications are discussed.
