Great Blue Heron’s Gorgeous Wings Akimbo in Molt
Question: How do great blue herons fly when they’re molting?
Some birds molt by dropping most of their feathers at the same time, and then go into hiding while the new feathers are coming in.
As you can see from the top photo, this young great blue heron has only dropped a full layer of wing feathers already. For comparison, the photo here below shows the intact wing feathers.
It was a treat to observe the molting young great blue heron that summer. Birds in molt tend to make themselves scarce, hiding away until they have regained solid flight, to keep safe from predators. This young heron chose my favorite cove as a hideout, and so I was able to photograph for a couple of weeks, well-hidden in a natural-cover blind along the shore.
The heron was able to fly while missing that layer of feathers, but lifting off and gaining altitude seemed slow and clumsy compared to the heron’s usual gracefulness. Coming in for a landing was also awkward – with fewer heathers to act as “brakes.” If you look closely at the top photo here, you can see that the heron’s neck and head feathers are all erect. That isn’t a configuration that’s part of their usual landing, and I had the impression that the bird was straining to use all of its feathers – even neck feathers – to land.
Great blue herons have special downy feathers that crumble and create a powdery substance they use to clean their other feathers. While the powder down feathers are most comminly mentioned as occurring on the heron’s chest, I believe that the bright white bands you see in the top photo give a good look at other layers of these special feathers.
