Bill lengths of first and consequent catches

Bill lengths of bar-tailed godwits (Limosa lapponica) at time of first capture and bill lenghts of birds recaptured (> 1 yr)

Predicted Energy Intake Rate (PEIR)

Prey burying depth per month and year, energy and density per m2, the predicted a (exp.a; area of discovery) and predicted handling time (Th) and the intake rate (PEIR)

Mean bill length of bar-tailed godwits (Limosa lapponica)

Mean bill length of bar-tailed godwits (Limosa lapponica) captured and/or resighted in the Dutch Wadden Sea and the Wash (UK)

Percentage of energy (AFDM) in diet

Percentage of energy content (AFDM g) in diet of bar-tailed godwits (Limosa lapponica) per month based on observations and dropping analysis. Dataset includes mean burying depth of lugworms (cm), mean bill length (mm) of Dutch Wadden Sea birds only and the mean PEIR (predicted energy intake rate)
