Frequently Asked Questions
Feeding, hygiene, nest boxes, water, and deterring squirrels and rats...
Should I feed garden birds all year round?
Yes, you can feed birds throughout the year. While winter feeding is well known, food shortages can also happen in spring and summer (especially when adult birds are feeding chicks, or after prolonged wet weather). The key is to feed responsibly, keep stations clean, and avoid letting old food build up.
What should I feed birds, and when?
Different birds prefer different foods, but the general approach is to match food to seasonal needs.
Autumn and winter: Birds need high-energy food to maintain body heat and build fat reserves. Suitable feeds include black sunflower seeds, sunflower hearts, suet cakes, fat balls, peanuts (in mesh feeders), and mixed seed blends designed for winter feeding.
Spring: Birds benefit from higher-protein options to support breeding and chick-rearing. Recommended feeds include mealworms (dried or live), sunflower hearts, soft food mixes, and protein-rich seed blends.
Summer: Natural food is often more available, but topping up can help during demanding periods (nesting, fledging) and during poor weather. Light seed mixes, sunflower hearts, soaked sultanas, and small quantities of mealworms are ideal summer feeds.
If you want to attract a wider mix of garden birds, it helps to offer variety and avoid letting food go stale or damp in feeders.
Are there foods I should avoid feeding birds?
Yes. A simple rule is: avoid foods that are salty, sugary, or prone to going mouldy. The National Trust specifically advises putting out bird food (not bread) in winter, and to keep feeding areas clean.
Also avoid leaving any food out that is damp, mouldy, or has clumped together. Old food should be removed promptly.
Where should I place feeders and feeding stations?
Aim for a spot that is quiet and where birds won’t be disturbed, but also where they can feed safely. The RSPB recommends choosing a location that suits birds’ safety and avoids disturbance, and ensuring feeders don’t allow old food to build up.
The National Trust also recommends situating boxes and feeders well out of reach of cats, and keeping feeders clean.
Practical placement tips:
- Keep feeders far enough from dense cover that cats can’t easily ambush birds.
- Keep them close enough to shrubs/trees that birds have a quick escape route.
- If you can, rotate feeding spots occasionally to reduce waste build-up on the ground.
How often should I clean bird feeders?
Regular cleaning is one of the most important things you can do for bird health. BTO best-practice guidance recommends cleaning and disinfecting feeding stations and bird baths regularly (for example, weekly) to prevent build-up of waste and droppings.
Garden Wildlife Health also emphasises routine hygiene precautions when feeding birds.
A good routine:
- Clean more often in warm, damp weather or if lots of birds are visiting.
- Empty out old food before topping up.
- Let feeders dry fully before refilling (damp = mould risk).
What should I use to clean feeders, and what should I avoid?
UK wildlife hygiene guidance supports cleaning with warm soapy water and/or an appropriate bird-safe disinfectant, rinsing thoroughly, and allowing equipment to air-dry completely before reuse.
Best practice:
- Use hot/warm water, a dedicated brush, and a suitable disinfectant used at the correct dilution.
- Rinse thoroughly so no residue remains.
- Keep cleaning tools used for feeders separate from household cleaning tools.
Avoid:
- Strong, highly scented cleaners that may leave residue.
- Using feeder-cleaning brushes for anything else.
- Cleaning feeders over kitchen sinks (do it outside if possible).
How do I keep bird baths and water stations clean?
Bird baths can spread infection if they’re not cleaned regularly, because sick birds may contaminate water with saliva or droppings. BTO highlights bird baths as a key place disease can spread and recommends keeping them clean and disinfected.
Good routine:
- Empty and scrub every few days (daily in hot weather)
- Rinse well and refill with fresh water
- Place water away from feeders if possible to reduce contamination from dropped food.
When and how should I clean nest boxes?
Clean nest boxes once breeding season is over, typically in autumn. Always be observant to ensure the nesters are empty before checking. Cleaning helps remove old nesting material and parasites. UK wildlife guidance recommends cleaning nest boxes as part of good bird-care practice.
How to do it:
- Always wear gloves.
- Remove old nesting material
- Use hot water and a brush; allow the box to dry fully before rehanging
- Avoid pesticides or strong chemicals inside nest boxes.
What nest boxes are “best” for UK garden birds?
The best nest box is the one that matches the bird species and is correctly placed. In the UK, small-hole boxes are commonly used for tit species, while open-front boxes can suit birds like robins and wrens (in sheltered locations). The National Trust also promotes providing bird boxes as part of a wildlife-friendly garden.
General tips:
- Put boxes up well before nesting season (winter is ideal).
- Place them out of reach of cats and in a sheltered position.
Do bird feeders attract rats & mice?
Rats are most often attracted by food that ends up on the ground. You should practice good hygiene and sensible precautions around feeding, which includes reducing waste and keeping feeding areas clean.
To reduce risk:
- Feed little and often rather than overfilling
- Clear up spilled seed and husks regularly
- Avoid placing feeders near dense ground cover, sheds, or compost areas where rats can hide.
How can I deter squirrels without harming birds?
Squirrels are attracted by easy, reliable food. The most effective deterrents are based on reducing access and reducing “reward”.
To reduce risk:
- Site feeders away from jump-off points (trees, fences, sheds)
- Hang from loose but sturdy branches, this makes it difficult for rats and squirrels
- Avoid overfilling; keep food fresh and quantities sensible
- Keep the area tidy so squirrels aren’t rewarded by spillage.
What should I do if I think there’s disease at my feeding station?
If birds appear unwell (fluffed-up, lethargic, or reluctant to fly), it’s sensible to take preventative action. A cautious approach:
- Stop feeding temporarily
- Do not touch the affected bird, see Avian Flu information
- Remove and thoroughly clean feeders and water stations
- Clear and clean the ground beneath feeding areas
- Resume feeding once everything is clean and dry.
What’s the simplest “golden rule” for feeding garden birds responsibly?
Offer appropriate food, keep it fresh, keep feeding areas clean, and don’t allow waste to build up. This aligns with major UK guidance that stresses feeder hygiene and thoughtful siting to reduce disease and unwanted visitors.
