How important are berries to the outside nature? That’s what we’re going to talk about today. Hi, this is Jill from the North Woods talking about nature topics right outside your front door.
Well, berries are pretty important to us too. They’re very nutritious and good for us. But for nature, berries are one of the most underestimated food sources out there.
Think about it. Long after flowers fade and the insects disappear, berries remain as a concentrated packet of summertime energy. Many shrubs and trees have different kinds of fruit on them, but they don’t drop their fruit right away. You know, we see that, like you get an apple and the apple falls from the tree as soon as it’s ripe and ready to go.
But many of the shrubs and trees keep their fruits at all times. They hold on to them as much as they can. A lot of those are bright red, or purple, or blue ones we see, even in the wintertime against the white snow. They are there as survival tools for the trees and the shrubs themselves.
They store an incredible amount of sugar and even some fats in there that help them grow during the growing season, preserving sunlight’s energy in these little tiny balls. And then during the hardest months of the year, namely wintertime, when the landscape looks kind of desolate and empty to us, the berries are signals that food is still available.
When you look at birds, a lot of insect eaters leave. We don’t have insects in winter. Seed eaters—some stay and some go—because seeds get covered by snow, but enough are still available for those birds to survive. Then you have the berry eaters.
Think about cedar waxwings or robins. All sorts of birds eat berries packed full of sugar to survive cold winters. Robins are a perfect example of flexibility. In summer, they eat worms and bugs. Once the ground freezes, they shift almost entirely to berries.
Flocks of robins move from tree to tree—crab apples, hawthorns, certain ash trees, serviceberries. The berries hang there untouched and available for a long time.
Cedar waxwings go even further. They’re almost entirely dependent on fruit. They travel in tight flocks, little gangs of twenty, moving from tree to tree. A tree full of berries can be stripped clean in minutes.
Berry-bearing plants don’t just feed individuals. They create gathering spots. A single tree can attract robins, waxwings, bluebirds, mockingbirds, and overwintering sparrows all at once. A quiet yard can suddenly fill with birds, and then just as quickly, they’re gone.
I planted serviceberries in my backyard, and I see birds hopping to them all the time.
Mammals enjoy berries too. Deer browse for them. Foxes and coyotes look for fallen fruit. Squirrels stash berries with nuts, and sometimes forget those caches. Mice and voles search for them under the snow, leaving tracks and seed fragments behind.
Not all berries are appealing right away. Some are bitter or dry when they ripen, discouraging animals from eating them too early. Freeze-thaw cycles soften them, making sugars more available and spreading food across the season.
Sometimes berries ferment. Yeasts break down sugars, creating small amounts of alcohol. Birds like cedar waxwings can get slightly intoxicated, leading to clumsy flying or dazed behavior. It’s usually harmless and a little funny.
Winter looks barren, but then you notice red dots on branches. We started winter hiking a few years ago and were surprised to find shrubs full of berries—beautiful against the snow and full of life.
Winter is not a stall of nature. It’s another chapter with different strategies. Paying attention to berries shows how food and energy continue to move through the landscape.
Now that I can see my serviceberry tree from my window, I watch more birds come and go. You can plant native berry plants too. They’re built for your environment, and animals recognize them as food.
It’s a fun experiment that supports wildlife and gives you something to enjoy right outside your door.
