The geese may start the season with a dozen little goslings but by the end of May they’re getting a little twitchy and a lot less cavalier about things eating their babies.
Some will tough it out, doing what they can to at least have something to show for their great expenditure of effort, but others will leave with whatever remains of their brood, heading overland in search of safer water. Things must be pretty bad if geese are willing to risk walking their last child through the woods, but it makes a certain sense.
These guys don’t run very fast.
