Warm weather can be a busy time for garden birds. Adult birds are feeding young, fledglings are starting to appear, and regular visitors may be using the garden several times a day for food and water.

Although winter is often seen as the main season for feeding birds, summer brings its own challenges. Dry ground can make it harder for birds to find worms and insects. Water sources can disappear quickly. Food can spoil faster in feeders. With a bit of care, your garden can still be a safe and useful place for birds during warmer months.

Provide fresh water every day

Fresh water is one of the most useful things you can offer birds in warm weather. Birds need it for drinking, but they also use it to bathe and keep their feathers in good condition.

A shallow bird bath or dish is enough. Keep the water clean, refill it daily and place it somewhere birds can use it safely. It should be close enough to shrubs or hedges so birds can retreat if needed, but not hidden so well that cats or other predators can approach easily.

During dry spells, water can attract birds that might not otherwise visit your feeders.

Keep feeding, but use smaller amounts

Birds still benefit from food in summer, especially when they are raising young. Parent birds spend a lot of energy feeding chicks, and fledglings need regular food while they learn to feed for themselves.

The main difference in warm weather is that food should not be left sitting for too long. Fill feeders with smaller amounts and top them up as needed. This keeps the food fresher and reduces waste.

If seed is being left behind, reduce the quantity rather than letting it spoil.

Choose suitable summer food

Good summer feeding is about offering food birds can eat easily and safely.

Sunflower hearts are a useful option because they are high in energy and have no husks, reducing mess under feeders. A good wild bird seed mix can also work well, especially if it contains ingredients that smaller garden birds will actually eat.

Mealworms can be helpful during breeding season, as many parent birds look for protein-rich food for their young. If using dried mealworms, soak them first to soften them.

Avoid putting out whole peanuts loose during nesting season. If you do use peanuts, keep them in a proper mesh feeder so birds cannot take large pieces.

Clean feeders more often

Warm weather can make dirty feeders a bigger problem. Damp seed, old food and bird droppings can spread bacteria and disease.

Check feeders regularly and remove anything wet, mouldy or clumped together. Wash feeders with warm water, let them dry properly and refill them with fresh food. Bird tables and ground-feeding areas should also be cleaned regularly, especially if birds are feeding in groups.

It also helps to move feeders slightly from time to time so waste does not build up in one place.

Keep food out of strong sun where possible

Seed and suet can spoil more quickly when exposed to direct heat. If possible, place feeders where they get some shade during the hottest part of the day.

This does not mean hiding them away completely. Birds still need to feel safe and have a clear view around them. A shaded spot near shrubs, hedges or small trees usually works well.

Storing bird food properly also matters. Keep seed sealed, dry and away from heat so it stays fresh before it goes into the feeder.

Make the garden safer for fledglings

Young birds often spend time on the ground after leaving the nest. They may look vulnerable, but in many cases their parents are nearby and still feeding them.

If you see a fledgling, leave it alone unless it is in immediate danger. Keep pets away from the area where possible and avoid disturbing it. Food and water nearby can help the parent birds continue caring for their young.

This is also a good reason to keep feeding areas clean and avoid leaving spoiled food on the ground.

Provide shade and cover

Birds need places to rest, hide and cool down. Hedges, shrubs, climbers and small trees all provide useful cover in warm weather.

A garden does not need to be large to help birds. Even a few planted areas, a quiet corner or a hedge can give birds somewhere to shelter between feeding visits. Less tidy areas can also support insects, which are an important natural food source for many birds during summer.

Watch for signs of spoiled food

Food can go off faster in warm conditions. Seed that smells musty, looks damp or has started to stick together should be removed. Suet products should also be checked regularly, especially during hot spells.

Fresh food is safer for birds and more likely to be eaten. It also keeps feeding areas cleaner and reduces the chance of attracting pests.

Supporting birds through summer

Warm weather can be a good season for garden birds, but it is not always easy for them. Dry ground, limited water, busy nesting periods and spoiled food can all cause problems.

By providing fresh water, clean feeders, suitable food and safe cover, you can help birds stay healthy through the warmer months. These small habits are easy to manage and can make your garden a reliable place for birds to feed, drink and raise their young safely.
