Woodpigeon Columba palumbus movements in eastern England

Capsule Woodpigeons range over greater areas during winter than summer with winter dispersion greatest in the first two winters following fledging.

Aims To radiotrack Woodpigeons, to analyse the BTO ringing recoveries and to examine ranging behaviour.

Methods Movements of 19 adult and nine newly fledged Woodpigeons around a 1070-ha study site in eastern England were monitored by radiotracking. The BTO recovery data were analysed for birds ringed in arable areas of Britain during the period 1950 to 1999.

Results The mean 95% minimum convex polygons during the summer were 254 ha for adults and 294 ha for juveniles. These ranges increased to 628 ha for adults and 1283 ha for juveniles during winter. Although they left the study area over the winter, some radiotagged juveniles returned to their natal areas the following summer. Winter dispersion followed by a return to the natal area the following summer only occurred for the first two years of life.

Conclusion Although Woodpigeons are largely sedentary, the winter dispersion of juvenile birds will weaken any effect of localized winter shooting on the numbers of breeding birds in that area the following spring.
