Hi Peter,
Thanks for the information on the Geese. It certainly is good to know the
re-introduction has been so successful. The birds must certainly disperse
in very small groups because I could find very few records of sightings in
Birdline or B-A. It seems that they don't get a mention until there is a
major congregation somewhere. I wonder where they went during the drought
years of 2000 - 2010? Anyway, thanks for solving the problem.
cheers
Jenny
