This small perky little bird is one of the most common birds in the Netherlands. It may be small but it is extremely boisterous. In fact, you hear wrens more often than you see them. They are forest birds, but will make their nests anywhere where you find trees. Hundreds nest in gardens, parks, woods and even in the dunes nowadays. They eat small animals, such as spiders and insects. But when scarse, they easily switch to seeds and berries.
