Capsule: Common sandpipers stopping over in a tidal marsh in northern Iberia during the autumn migration period showed a moderate mean fuel load and low fuel deposition rate, but relatively long stopover periods, suggesting a ‘hopping’ strategy of migration. Aims: The main objectives of this paper were to analyse the stopover ecology of migrant Common Sandpipers at Txingudi coastal marshes, northern Iberia, in autumn. Methods: Common sandpipers were captured during the autumn migration of 2007–2013 at the Txingudi marshlands (province of Gipuzkoa, northern Iberia). Data were obtained from a constant effort ringing station working on a daily basis. Results: We observed a moderate fuel load and fuel deposition rate and long stopovers. Conclusion: Our results suggest overall a ‘hopping’ migration strategy. When moving along the coast of northern Iberia, Common Sandpipers may not use key wetlands to gain much fuel, as found in other waders or in some wetlands of inland Iberia, but all coastal marshes seem to be potentially used in the same way.
