A migrating Trumpeter Swan is off the mouth of Kokanee Creek. Others have seen one at the Park for a few weeks, but this is my first sighting, albeit it far out on the Lake.
A Mallard couple has promptly taken advantage of the swan’s presence. With its long neck the trumpeter can feed in deeper water than can a dabbling Mallard. But, when the swan stirs up edibles from the bottom, the Mallards can feed in deeper waters.
What a wonderful way to co-operate.
Birthe, cooperation? My guess is that the swan gets nothing out of this, and the Mallards are just taking advantage of the opportunity. But, that is OK.
How lovely. Thank you
