The Most Dangerous Place: A Brood of Common Mergansers on the Missouri
It was June of 2010, and I was running point counts along the Missouri River near Bismarck. I had a small camp set up above the riverbank, just enough to move between survey points without packing everything up each time.
Mid-morning, a female Common Merganser wandered into camp with eleven chicks behind her.
She didn’t belong there, and she seemed to know it.
The whole group had that tight, alert feel to it. Not panicked, but uneasy. She paused briefly, scanned the area, and then made a decision. Without much warning, she lifted off and dropped down toward the river below.
The chicks couldn’t follow her in the air. Instead, they hesitated for a moment, then started making their way to the edge of the bank.
It was steep, around twenty feet down.
From where I stood, it didn’t look like a great situation.
They reached the edge in a loose cluster, peering over, shifting, calling softly. For a moment, it felt like they might stall there, with something in them registering the height and holding them back.
But whatever hesitation was there quickly gave way to instinct.
One jumped. Then another. Then the rest followed.
No wavering. No guessing. In the moment, it was simply a quick, decisive commitment.
The Real Danger
From a human perspective, it can appear reckless. Eleven small birds throwing themselves off a steep bank into open space. But standing there watching them, it became obvious that the drop wasn’t the dangerous part.
Where they started was the real danger.
Merganser chicks are precocial. Within hours of hatching, they’re already moving, following, and functioning as part of the brood. Unlike humans, there’s no long adjustment period where they are eased into things. Movement is built into their survival instinct from the start.
On land, especially in the wrong place, they’re exposed. To predators, to separation, to cold, to simple disorientation.
The longer they stay there, the worse their chances get. The river is where they’re meant to be. That urgency changes everything.
What looks like a risky decision from the outside is actually the safer one. Evolution has already worked that out. The chicks are light, insulated, and built in a way that makes a fall like that far less consequential than it appears. What would be a serious problem for something larger, heavier, or less adapted simply isn’t for them.
The Safest Choice
Staying put would have been the riskier choice.
I shifted a little as I watched it happening. Not to intervene so much as to keep the situation from becoming more chaotic. Just enough to give them a shorter path to the edge without scattering them further. In moments like this, doing too much would make things worse, but doing nothing at all doesn’t feel quite right either.
They didn’t need help. They just needed to keep moving.
One by one, they hit the water, disappeared briefly, and then popped back up. Within seconds they were paddling, orienting, calling. The female circled nearby and pulled them back together.
What had looked disorganized from above settled almost immediately into a tight, moving group again.
A line. A direction. Back to what they had been doing before they wandered into camp.
It’s easy to focus on the jump. The height, the drop, the moment where it feels like something could go wrong.
But that wasn’t really the danger. The danger was where they started, even if only for a short time. Exposed. Delayed. In the wrong place.
For those chicks, the choice wasn’t between jumping and staying safe. It was between jumping and staying vulnerable. And they didn’t hesitate.
