Blue Tits famously learned to peel back the foil tops of milk bottles left on doorsteps in Britain — a behavior that spread across the country in the early 1900s.
Pairs raise a single huge brood of 8–14 eggs, timed to coincide with the peak abundance of oak caterpillars.
Their azure crown reflects ultraviolet light invisible to humans; UV-bright males are preferred by females.
Blue Tits are confiding garden birds across Europe, easy to attract with a small nest box and standard garden feeders.
Sunflower hearts, peanuts, suet, and mealworms. Tube feeders, peanut cages, and tray feeders all work.
Mount a 25–28mm hole box 1.5–4 m up on a tree trunk or wall, away from direct sunlight, with a clear flight path in.
Native deciduous trees — oak especially — and dense shrubs nearby for cover.
Shallow bird bath. They bathe regularly even in winter.
House Sparrows can crowd them out near buildings. A 25mm hole excludes sparrows.
Don't use chemicals on your garden — caterpillars are essential nestling food.
A widespread Eurasian woodland bird — a backyard staple from Ireland to Russia.
Common year-round in gardens, woodlands, and parks throughout.
Resident across the continent except the far north of Scandinavia.
Resident around the Mediterranean coast, with a separate subspecies in North Africa.
Mixed deciduous woodland, hedgerows, mature gardens, parks. They especially favor oaks for the caterpillars they feed nestlings.
Body sized to 4"×4" floor. The 1⅛" panel locks out larger nest competitors while letting the Eurasian Blue Tit pass cleanly.
