Leave it to Mark "Sparky" Stensaas to find great footage and fine stories about North Shore natural history. And thank goodness for telescopic lenses.
Sparky caught some great action this spring. Diving ducks have goofy, elaborate courtship rituals, but the shows are for the females, not the birdwatcher. Generally the show is so far away from shore, the average person never sees them.
The video shows hooded mergansers doing a bizarre head pump, common goldeneyes doing a ballerina-like neck stretch, and three frenetic male common mergansers trying to out-goofy each other in the presence of one disinterested female.
Thanks for catching the show, Sparky!
