I was intrigued by the record of a Wood Pigeon and Collared
Dove on Tory Island recently and decided to check there migratory habits in the
BTO Migration Atlas.
Wood Pigeon
The BTO Migration Atlas suggests that the species is
sedentary although juveniles tend to move further than adults. Although there
is apparent visable migration on the east coast of England ringing recoveries
would suggest that only a small number of birds actually emigrate and there are
few immigrants from continental Europe.
The maps on the atlas would also suggest there are 5
recoveries of birds ringed in Britain and recovered on the island of Ireland,
including one ringed on the Isle of Man and recovered in County Down.
Collared Dove
Collared Dove which originally colonised Britain and Ireland
in the late 50’s and 60’s show a much greater willingness to move around than
Wood Pigeon. There are about a dozen records of
Collared Doves ringed in Britain and recovered in Ireland and one ringed in
continental Europe and recovered in Ireland.
Collared Dove dispersal distance has decreased since the
1970’s, indicating the population is becoming more sedentary.
