I follow some Eurasian Spoonbills (Platalea leucorodia) with GPS-telemetry in Hungary.
They stay within the Carpathian Basin during their dispersal in summer/autumn. Dispersal movements occur in all directions, including in the southward direction as well in summer and autumn in the Carpathian Basin. Of course, Spoonbills before their autumn migration move in the southward direction, and birds may stop for hours/days/weeks in proper wetlands of the Carpathian Basin. As soon as they leave the Carpathian Basin they are clearly on their autumn migration.
Generally, "my" Spoonbills that were hatched in Hungary can breed any suitable wetland in the Carpathian Basin. Adults visiting even 3-7 colonies as soon as they reach Carpathian Basin in spring when they move northward direction.
Could you recommend publications, or share your experience how can I separate post-fledging/post-breeding dispersal from autumn migration? And, how can I separate pre-breeding dispersal of adults from the end of spring migration?
Thank you for your answer and your kind help in advance!
