The robin might seem cute, but it is actually a highly territorial bird and will aggressively defend its domain against others. These much-loved birds are on the rise as the UK robin population continues to increase.
Explore facts about this red-breasted festive icon.
The robin is a small, plump bird. Its black beak is short and thin.
Males and females look identical, sporting a brown back, white belly and red breast, face and cheeks. In contrast, juveniles are speckled gold and brown, only developing the distinctive red plumage in adulthood.
A robin's diet consists of seeds, fruits, insects, worms and other invertebrates. It will also visit garden bird tables and feeders to feed on scraps and mealworms.
Relatively unafraid of people, robins often follow gardeners around to take advantage of freshly dug-up worms and even feed from people's hands.
Robins are widespread throughout the UK, inhabiting farmland and woodland, as well as gardens and parks in towns and cities.
Both male and female robins hold territories, as a pair in summer and as individuals in winter. They will defend these with surprising ferocity, driving off intruders and making their presence known by singing loudly from conspicuous perches.
During courting, the female is permitted to enter the male's territory. The breeding season usually starts in March, but courting can begin in January if its mild. The male supplies more than a third of his mate's food throughout this period.
Using dead leaves, moss and hair, the female builds a cup-shaped nest low to the ground. She hides it in nooks and crannies in tree roots, or among shrubs and climbers, such as ivy. More unusual nesting locations include old wellies and plant pots.
Robins are sensitive to disturbance during nest building and egg laying and will easily desert their nest if they think it's been discovered.
The female typically lays four to six eggs, which she incubates for 13 days. Once chicks hatch, the female immediately removes the eggshells from the nest.
Both parents look after the nestlings, which are dependent on them for food and warmth. The chicks fledge at 14 days but continue to be cared for, predominantly by the male, for a further three weeks.
Robins have at least two broods a year, with nestlings around as late as the end of July.
Robins can be seen all year round in gardens, parks and hedgerows, in both the countryside and urban areas.
To spot one look out for a bright red breast and listen out for its song. Unlike other birds, robins sing throughout the year, apart from midsummer when they're moulting. The robin is one of the first birds to start singing in the dawn chorus and one of the last to stop singing in the evening.

Robins often become quite brave around people and may approach you if you are quiet.
Robins are natural ground feeders so feeding trays are the best way to encourage them into your garden. You may also observe them clearing up scraps that have fallen from hanging feeders. Mealworms are a particular favourite of robins, but they also find sunflower hearts very palatable.
The UK robin population has increased by 45% since the 1970s and continues to rise.
The biggest threat to robins is prolonged, severe winter weather. During cold nights robins use up to 10% of their body weight to stay warm. If they are unable to replenish these fat reserves, it can be fatal. Providing food on bird tables during cold weather can make a big difference to their survival.
The robin became the iconic bird of Christmas in the Victorian era, when postmen were nicknamed robins due to their red waistcoats. Robins began to appear on Christmas cards to represent the postmen who delivered them.
... or that it helped you learn something new. Now we're wondering if you can help us.
Every year, more people are reading our articles to learn about the challenges facing the natural world. Our future depends on nature, but we are not doing enough to protect our life support system.
British wildlife is under threat. The animals and plants that make our island unique are facing a fight to survive. Hedgehog habitats are disappearing, porpoises are choking on plastic and ancient woodlands are being paved over.
But if we don't look after nature, nature can't look after us. We must act on scientific evidence, we must act together, and we must act now.
Despite the mounting pressures, hope is not lost. Museum scientists are working hard to understand and fight against the threats facing British wildlife.
For many, the Museum is a place that inspires learning, gives purpose and provides hope. People tell us they 'still get shivers walking through the front door', and thank us for inspiring the next generation of scientists.
To reverse the damage we've done and protect the future, we need the knowledge that comes from scientific discovery. Understanding and protecting life on our planet is the greatest scientific challenge of our age. And you can help.
We are a charity and we rely on your support. No matter the size, every gift to the Museum is critical to our 300 scientists' work in understanding and protecting the natural world.
From as little as £2, you can help us to find new ways to protect nature. Thank you.
