Canadian Geese Walking, Honking

It's not unusual to see waterfowl on the small lake behind our house, but I figured once the thing had frozen over for the winter, the 'duck, duck, goose' show was over. As we discovered this morning, that's not the case. A gaggle of Canadian Geese have somehow landed on the icy surface and are just walking around and maybe drinking a little of the top-surface melt. Of course I can't let Yuki free back there for fear that the dim-witted animal would charge the geese and crash through the ice.
