Living with Birds Blackbirds: Masters of the lawn Tweetapedia

Taking centre stage

March marks a turning point in the garden. While the more colourful blue tits and goldfinches dominate hanging feeders, the blackbird is often the unsung hero of the spring landscape. By late March, their presence becomes impossible to ignore, transitioning from quiet foragers into the primary architects of the dawn chorus.

The evening soloist

As the evening light lingers longer, it is the blackbird that defines this shift. You will usually notice him perched on the highest available point - a chimney pot, the top of a tall tree, or a fence post - singing a complex, melodic song to ward off rivals and attract a mate.

While other birds rely on repetitive calls, the male blackbird is a true composer, using a flute-like, melodic song to establish territory. Unlike the frantic chirping of smaller finches, his song is mellow and sophisticated. Accomplished mimics, they are also capable of incorporating sounds from their environment into their songs.

Thrashing foragers

Blackbirds are specialised ground-feeders. As the soil warms up in late March, earthworms begin to move closer to the surface, and you will likely see blackbirds tilting their heads to one side. They're not listening but focusing their eyes to detect the slightest movement in the grass.

Using their sturdy beaks, they toss aside leaf litter in search of beetles, spiders, and caterpillars. They require high-protein invertebrates to build up the physical reserves needed for egg production. If the ground is hard or frozen, they rely heavily on fallen fruit.

The colour of a good mate

Pairing usually cements in early spring, often preceded by ‘ground runs’ where the male pursues the female with his tail fanned and head bowed.

The adult male’s plumage is a deep, uniform black that contrasts sharply with his bright orange-yellow eye ring and beak. Female blackbirds use beak colour to judge a male's fitness. A brighter, more orange beak often signals a healthier, stronger male with fewer parasites.

Behind a curtain of ivy

Late March is a critical window for nesting. Female blackbirds, distinguished by their subtle brown plumage and streaked throats, are currently busy scouting for secluded spots in ivy or thick hedges. They are industrious builders, using mud to reinforce their cup-shaped nests.

Offering a small patch of damp soil or leaving leaf litter undisturbed provides them with the essential building materials and invertebrate snacks required to raise a healthy brood. They typically lay 3-5 eggs, which are turquoise with rust-colored spots.
