My sister in AR reported watching a surprising encounter between
mallards (wild) and Canada geese. Her contingent of 8 mallards seem to
get along okay on their pond, but when 4 Canada geese flew in and
alighted, the ducks took exception. She reports the ducks encircled the
geese, then kept tightening the circle until the geese got the
unfriendly message and took off. Given the size difference I found their
response and giving ground ( well, water) surprising. Has anyone seen
similar interactions?
