What Are Fledglings? What Baby Birds Eat and How to Help Them

Spring and early summer bring a surge of young birds into British gardens. Many people start spotting fluffy, awkward-looking birds that hop on the ground or perch low in shrubs. These birds are referred to as ‘fledglings’. 

This just means they are a young version of garden birds we all know and love. If you’ve ever wondered what they are, what they eat, and if they ever need help, we’ve got you covered. Although the answer may surprise you, young birds tend to be exactly where they need to be, even if they don’t look it!

In this guide, we’ll explain what fledglings are, what they eat, how adult birds care for them, and when they may need help.

What Are Fledgling Birds?

Fledgling is the stage in a bird's life between hatching and being an independent bird. They are young birds that have recently left the nest, but they are not yet fully independent and still rely on their parent birds.

At this stage in their life, fledgling birds are almost fully feathered, can hop, flutter, and make short flights. Because they are still learning, they often appear clumsy or scruffy, which can make them stand out in our gardens. When they leave the nest, young birds strengthen their wings, practise flying, learn to forage, and start to become the birds we know and love!

Depending on the species, fledgling birds do look quite different. Small garden birds, such as the Blue Tit or Robin, appear fluffy and compact, with short tails. Compared to larger birds like the Crow or Blackbird, who can seem full-sized with just duller plumage!

Fledgling vs Nestling: What’s the Difference?

During nesting season, there are two stages for baby birds. When they can't get out of the nest, baby birds are called 'nestlings'.

Nestlings

Nestlings are really young birds that only have a few feathers. Unlike fledgling birds, they are unable to leave the nest and depend completely on their parents.

Fledglings

Fledglings are feathered, can leave the nest, and are beginning to learn independence. They are still fed by their parents.

If a young bird is fully feathered and hopping around, it is likely a fledgling and is probably not abandoned.

What Do Fledgling Birds Eat & What to Feed Baby Birds?

What do fledgling birds eat? It's a common question, and it does differ between species, but most birds eat the following!

Insects and Invertebrates

For many baby birds, insects are crucial for growth because they are rich in protein and provides balanced nutrition. Parents will feed caterpillars, beetles, spiders, worms, flies and other soft bodied insects.

Robins, tits, and wrens rely heavily on insects for feeding fledglings.

Seeds and Grains

Some species, such as finches and sparrows, may be introduced to small seeds, grass seeds and crushed grains. Often, these are softened or partially processed by the parents first.

Berries and Fruit

As fledglings mature, some birds may begin sampling some more fresh food like berries and fruit. Elderberries, hawthorns and other soft fruits are just some favourites.

Should You Feed a Young Bird Yourself?

In most cases, no. It’s best not to feed a fledgling directly unless advised by a wildlife rehabilitator. Young birds often have very specific dietary needs, and the wrong food can harm. The best way to help is to support the parent birds.

How to Help Fledglings & Wild Birds in Your Garden

Provide Fresh Water

A shallow bird bath or water source can help adult birds and newly independent young birds, particularly in warm weather.

Offer Natural Food Sources

Wildlife-friendly planting can support insects and berries that birds rely on. Grow native wildflowers, nectar-rich plants and berry-producing shrubs.

Keep Cats Indoors During Peak Fledging Times

Young birds are vulnerable while learning to fly. Keeping cats indoors, particularly around dawn and dusk, can make a big difference.

Avoid Disturbing Young Birds

Fledgling birds are learning to be independent, so the typical advice is to leave them alone unless they are in immediate danger or injured.

When Does a Fledgling Bird Need Help?

While most fledglings should be left where they are, intervention may be needed if the bird. If you do find a fledgling on the ground, unless it is injured, it's best to leave it alone, as its parents are likely nearby and will continue to care for it.

• Is injured

• Has been caught by a cat

• Is in immediate danger (such as on a road)

• Has no feathers and has fallen from a nest (likely a nestling)

• Has been alone for many hours with no sign of parents

If in doubt, contact a local wildlife rescue for advice. Read our guide about helping injured birds to find out more!
