Natal and breeding dispersal in the Baltic Greylag Goose Anser anser.

Nilsson, Leif LU and Persson, Hakon (2001) In Wildfowl 52. p.21-30
Abstract
Dispersai from the centre o f the breeding range of the Baltic
Greylag Goose Anser anser was studied using observations
of individuals with neck collars. The median natal dispersal distance was 0 km in females and 25 km in mates, respectively. A ll of the females recruited to w ith in
7 km o f where they had been reared, 87% to the natal lake and 11% to
neighbouring water bodies. Of the mates, only 11% rec ruited to the natal
lake, while one individual was found more than 1,000 km from its place of
birth. Even though the males dispersed to a g reater distance within the population's breeding range, th e ir distribution was s till highly skewed towards
th e ir point o f origin. Two thirds of a ll mates recruited... (More)

where they had been reared. Once recruited, both sexes exhibited an
extremely strong p h ilopatry to th e ir breeding area. Only 1.5% o f the males
and 0.5% o f the females changed breeding site between successive years.
A lt breeding dispersal occurred within the local population, and in no case
exceeded 6 km. (Less)
