If you've looked out your window recently and thought,
"What's wrong with my cardinal?"
you're not alone.
Every summer, I receive emails from concerned bird lovers wondering why their bright red cardinal suddenly looks scruffy, patchy, or even bald.
The good news?
Your cardinal is probably perfectly healthy.
Why do cardinals lose their feathers?
Each summer, Northern Cardinals go through their annual molt.
During this process, they replace nearly all of their feathers with brand-new ones. Some cardinals lose feathers gradually, while others shed many of the feathers on their head at once, creating the famous "bald cardinal" look.
It may seem alarming, but it's a completely normal part of a cardinal's life.
Three surprising facts about molting
1. Cardinals replace thousands of feathers.
An adult cardinal may replace more than 2,000 feathers during its annual molt.
That's an incredible amount of new growth packed into just a few weeks.
2. Feathers are made mostly of protein.
Growing an entirely new set of feathers requires enormous amounts of protein and energy.
In the wild, many birds naturally increase the number of insects they eat during summer because insects provide the protein needed to grow healthy feathers.
That's one reason dried mealworms are such a great summer food for backyard birds.
3. Molting birds need excellent nutrition.
Growing new feathers is one of the most energy-demanding times in a bird's year.
A variety of high-quality foods helps provide the fats, protein, and nutrients birds need while replacing their feathers.
Should I be worried?
Usually, no.
A molting cardinal may look:
- Patchy
- Thin
- Less colorful
- Bald around the head
- A little grumpy
As long as the bird appears active and continues eating, molting is the most likely explanation.
If you notice growths, injuries, difficulty flying, or severe feather loss that doesn't improve over time, illness or mites could be involved, but that's far less common than a normal summer molt.
What should I feed molting birds?
Summer is one of my favorite times to offer birds a little variety.
Here are a few favorites that support cardinals and many other backyard birds:
- Cardinal Classic — A premium blend cardinals love.
- Dried Mealworms — Extra protein for bluebirds, wrens, chickadees, woodpeckers, and many birds during molt.
- Hot Pepper Blend — Helps feed birds while discouraging squirrels.
- Finch & Bunting Blend — Perfect for colorful finches and buntings.
If you want an easy solution, our Summer Backyard Collection includes all four together and saves you money compared to purchasing each separately.
