What to Feed Birds During Nesting Season

As nesting season begins in coastal South Carolina, birds enter one of the most demanding periods of their year.

Building nests. Defending territory. Laying eggs. Feeding hungry chicks.

All of it requires energy — and lots of it.

Here in Mt. Pleasant and the greater Charleston area, early spring often brings unpredictable cold fronts just as birds begin nesting. When natural insect activity dips during those cooler stretches, backyard feeders can provide a valuable nutritional bridge.

Why Are Birds Eating More Suet in Spring?

Many people are surprised to find that their suet feeders are even busier as we approach spring.

But it makes sense.

Parent birds are literally working themselves thin to:

• Construct nests
• Lay and incubate eggs
• Protect their territory
• Feed rapidly growing young

High-fat, high-protein foods are critical during this time.

Suet is one of the most concentrated energy sources birds can access. During nesting season, it helps replenish the calories burned throughout long, active days.

In early spring in the Lowcountry — especially during sudden temperature drops — that extra boost of fat and protein is greatly appreciated.

The Importance of Protein During Nesting

Protein needs increase substantially during egg-laying and chick development.

Protein supports:

• Muscle development
• Feather growth
• Overall chick health
• Faster fledging success

Insects are a primary natural protein source, but their availability can fluctuate depending on weather patterns.

Providing reliable high-protein bird food ensures nesting adults have consistent access to the nutrients they need.

Don’t Overlook Calcium

Calcium plays a vital role during nesting season.

It supports:

• Eggshell formation in females
• Strong bone development in chicks
• Healthy molting after nesting

Without adequate calcium, birds may lay fewer eggs or produce weaker shells.

Bark Butter® products naturally contain calcium, making them a valuable addition to your feeders during nesting season.

Will Feeders Replace Natural Food?

No — and they shouldn’t.

Birds will continue to forage for:

• Insects
• Native seeds
• Berries
• Caterpillars

A backyard feeder is a supplement — a reliable support system — not their sole food source.

The combination of native plants and high-quality feeder foods creates the healthiest environment for nesting success.

A Joyful Part of Nesting Season

One of the most exciting moments of the season is watching fledglings visit your feeders for the first time.

Young birds often appear:

• Slightly fluffy
• Curious and unsure
• Following closely behind a parent

Keeping a wide variety of foods available — placed in different spots around your yard — helps attract the greatest diversity of birds and supports them through this important stage of life.

Every yard is different.

Sun exposure, habitat, feeder types, and bird species all influence what will work best.
