Nurturing Winter Birds: A Guide to Supporting Avian Life

As winter descends, the natural food sources for birds dwindle, making supplemental feeding a crucial act of support. Providing food, water, and shelter can significantly increase their chances of survival during the coldest months. This guide, updated for 2026, offers practical advice on how to assist your garden birds thrive through winter, while also minimizing potential risks to their health.

Why Feed Birds in Winter?

December marks the beginning of periods of intense cold where natural resources become significantly scarce. During this critical season, garden birds face a dual challenge: increased energy needs to maintain their body temperature (around 42°C), and difficulty finding food. For example, tits require 15 to 20 calories daily when temperatures drop. Feeding birds isn’t just an act of kindness. it’s essential for maintaining local wildlife populations. The Ligue pour la Protection des Oiseaux (LPO) recommends providing food from November to the end of March to help species navigate the most challenging months of the year.

When and Where to Start Winter Bird Feeding

Nourishment can start as early as mid-November, when temperatures consistently fall below 10°C, as this is when natural resources start to diminish for birds. This period generally extends until the end of March, depending on climatic conditions. All birds frequenting your garden – tits, finches, sparrows, and blackbirds – can benefit from your assistance, each contributing to local biodiversity.

Choose locations that are exposed but close to trees or shrubs, which will serve as shelter.

What to Feed Garden Birds

Birds particularly enjoy black sunflower seeds, millet, and unsalted peanuts. Avoid processed foods like bread, pasta, and cheese.

Protect seeds from the elements using a silo feeder or one with a roof. Consider installing a small dish of lukewarm water to prevent freezing.

Maintaining Hygiene to Prevent Disease

Regularly cleaning feeders is crucial to prevent the spread of diseases through droppings. Salmonellosis, for example, can devastate species that live in groups (finches, siskins).

The LPO recommends dispersing feeders to avoid large gatherings, especially for highly gregarious species like finches, European siskins, and reed buntings. Different types of feeders (posers, suspenders, with trays, distributors) can be mixed.

Maintain impeccable hygiene by cleaning drinkers regularly, renewing the water daily if possible, and removing dirt and green algae by scraping.

LPO Recommendations and Timing

The LPO advises feeding birds only during periods of severe cold, from mid-November to the end of March.

Place the feeder and drinker in the center of the garden, in an open area, away from walls, bushes, and side branches to avoid uncomplicated access for predators (cats, martens).

The National Garden Bird Count will be held on January 24th and 25th, 2026.

Key Takeaways

• Feed birds during periods of prolonged cold, from November to March.
• Offer appropriate foods like sunflower seeds, millet, and peanuts (unsalted).
• Avoid bread, pasta, and cheese.
• Maintain clean feeders and drinkers to prevent disease.
• Disperse feeders to reduce the risk of disease transmission.
