Basal metabolic rate in migratory waders: intra‐individual, intraspecific, interspecific and seasonal variation
Summary Basal metabolic rates (BMR) were measured in 36 adult and 119 juvenile waders of 19 species on autumn migration in southern Sweden. In a comparison with literature data, it was found that juvenile BMR was generally lower than at the onset of migration in the Arctic and slightly higher than o...
