It’s on
The squads of Buffleheads visiting the bay are in full mating mode now. Neat, tiny ducks ‘hooking up’ or fending off rivals. Buffleheads are monogamous but young birds need to find a partner. They’ll try to steal one if there’s no other way. The activity out there is close to frantic. Everybody’s zooming around, the strikingly-patterned males and the more tastefully-garbed females. And there’s lots of splashing too. The tiny ducks don’t even notice the much larger Common Mergansers who cruise through the melee.
Common Mergansers-where?
It’s all necessary, of course. Things have to happen now, or never. Soon, the Buffleheads will leave the coast and migrate into the interior. The females will rear their young in nesting holes originally made by Northern Flickers in trees on small streams and ponds sans Northern Pike, those notorious duckling eaters. For a time, they’ll stop being sea ducks and become freshwater ducks (that’s remarkable too if you think about it). I won’t see them again until the fall, likely on the same date as last year–October 15. Buffleheads are the most punctual of waterfowl.
It’s how you look…
I should have more information about these charming little guys at my fingertips. I used to have a detailed monograph devoted to them, a surprise gift from my printer father years ago. Consistent with my life pattern of not needing something until after I’ve thrown it away, I got rid of it -reluctantly – a year or so ago. I’d carried ‘Buffleheads ‘ by Erskine around for decades even though it smelled rather strongly of the aquarium it fell into way back when. Plus its pages stuck together. It had to go. But now, I’m watching Buffleheads doing bobbing neck stretches, chasing each other in circles, flapping, displaying wing patterns and otherwise carrying on and, boy, I wish I still had that book. Sorry, Dad.
Bumper Birds
Now that I think about it, Bufflehead Bumper Boats might be a better title for this post. It’s the closest analogy I can think of. Males circle each other heads down, plowing through the water, raising the vertical crests on the back of their heads, show off the striking white patches on their wings, tearing around as fast as their little pink legs can drive them, bearing off just before the collision, like kids doing bumper boats. The myriad behavioural nuances obviously mean something. Erskine could have told me.
Picking Up Speed
Amongst themselves there must be worlds of difference between participants but I can’t tell one of these little showboats from another. And which bird wins? A better black and white pattern might carry the day, or the intensity of the iridescent purple sheen on a male’s head, or good ‘cheeks’ and nape ruff, or maybe the whole package. I suspect nerve and aggression figures in big time.
Any day now, they’ll be gone, off to their northern lakes and rivers and their nesting holes, not to return until October 15 when dozens will suddenly show up in the bay. I’ll miss the little guys, the smallest of the sea ducks.
