We're in for a weather change, Arctic air is about to be visited upon us. Canada geese were migrating today - flock after flock all morning long - from 5 or 6 birds (family groups?) up to large uncountable flocks. They would tack into the Westerly wind and then cut left and sort of glide to keep themselves on their SSE course. How do they know where they' re going? Are they led by parents and flock leaders who have made the trip before or is there a genetic component to their migration. I do know that the 'local' Canada geese appear to have lost all migratory instincts. What are your thoughts?
