A Birdwatcher’s Guide to the Chaffinch

The chaffinch is one of the UK’s most recognisable and colourful birds, commonly found across the country. With their bold, bright colours and lively nature, they are a welcome visitor to our gardens, readily enjoying the bird food we put out and making use of our trees for nesting. These finches thrive in areas with plenty of trees, particularly oak, where they can forage for food and seek shelter. The male chaffinch stands out with a rust-coloured breast, a slate-blue head, and brown wings with flashes of cream, while the female’s more muted, buff and brown plumage provides perfect camouflage as she incubates her eggs in the nest. Known for their loud, beautiful song, chaffinches also have a distinctive dipping flight pattern. Their strong, stout bills are ideal for eating seeds, though they will also enjoy a diet of insects.
Chaffinches are resident in the UK year-round, but over winter, they are joined by their Scandinavian cousins, whose migration almost doubles the population. Interestingly, females are more likely to travel further south than males, a behaviour known as differential migration. Chaffinches begin defending their territories as early as February in preparation for nesting in April. Their neat, mossy nests are often found in shrubs or trees, decorated with lichen for camouflage. During the breeding season, the male’s colours become more vibrant as the dull tips of his wings wear away to reveal bolder hues beneath. The female lays 1-2 clutches of up to eight pale blue eggs each season, and both parents feed the chicks insect larvae until they fledge between eleven and eighteen days.
Chaffinches are territorial birds and often return to the same nesting site year after year. Historically, they were kept as pets and entered into singing competitions during Victorian times, though this practice was outlawed in the late 19th century. Introduced to New Zealand in 1862, chaffinches have since become the country's most widespread bird. While they typically live for around three years, chaffinches are vulnerable to trichomonosis, a deadly disease affecting finches. To help protect them, it’s important to clean bird feeders regularly with warm, soapy water to reduce the spread of the disease.
