Hi:
I have only had my pond for 4 years but I have had the same two geese for three of those years. I always shoot at geese that land at my pond. One of the geese that is a permanent resident tries to run other geese off the property. The one will not run a group of 5 or more, but does a nice job with stragglers. I had 66 geese on my 1.5 acre pond a while ago. And the resident was squaking something bad. I do not have many that try to stay around, but the residents do not care if I fish or not.
Did have a weird experience with their nest this year, I have a small island that they nest on, problem with that, is that I hit floating golf balls on that island. This year they gathered up 8 golf balls and nursed them with thier 4 eggs, EGGS did not hatch. I assumed they gathered them before they laid and they gave up on them?

generally I do not have a problem with the geese wanting to stay around, I just thought it was because the resident geese are mean?
