Dispersal and migration of Eurasian spoonbills breeding in Croatia

In the period from 2003 to August 2012, a total of 138 birds (26.1% of all colour-ringed birds) were observed, with 443 resightings altogether. A total of 46.5% of the birds were observed as juveniles, 32.3% as immatures, and 21.2% as adults. Spoonbills ringed in Croatia were observed in ten countries, with the majority of observations reported from Hungary and Italy, apart from Croatia. Croatian spoonbills wintered in North Africa and southern Italy. Croatian spoonbills fly much shorter distances to wintering grounds compared to the Atlantic metapopulation: 700-1, 100 km to southern Italy and 1, 100 – 1, 500 km to Tunisia. Only a fraction of the immature spoonbills spend summer on the wintering grounds.
