Abstract
Dispersal of the White Stork Ciconia ciconia in the Lonjsko polje Nature Park, Croatia
There are two main types of dispersal: natal and reproductive. Natal dispersal is more common and individuals travel a greater distance than during reproductive dispersal. Direction and distances depend on various factors. Dispersal of the White Storks, Ciconia ciconia, was analysed using resightings of colour-ringed individuals in the Lonjsko polje Nature Park, Croatia. 36.7% observed individuals did not disperse outside the natal settlement, while only 14.3% covered a distance longer than 50 km. The median dispersal distance was 4.21 km (IQR = 0 - 8.8, n = 49); the correlation of dispersion with the number of nests in settlements and the size of the settlements was studied. Results have shown that storks are dispersing from settlements with a small number of nest to settlements with a large number of nests and that dispersal does not depend on the size of the settlement.
