Guide to the
Wren

Think you’ve spotted a Wren in your garden? Our Wren bird guide is here to help you learn lots of information about these little garden visitors.

Small in size and mostly brown in colour, they can be spotted all over the UK. Although they’re quite common, they’re still a lovely sight to see, with a round body and pointy tail. Due to their small size and skulking nature, they can be quite easy to overlook at times. However, their loud songs and calls often give them away.

You can find them in woodland and other areas with lots of undergrowth. They’ll usually lay and raise two broods between March and August. Generally, their nests are made from moss and grass close to the ground. If you happen to come across their eggs, they’re white in colour with faint brown specks. Want to keep these little birds well-fed? Their diet consists of insects and small seeds.
