The house sparrow is a small, social bird that often lives close to people. It eats seeds and small insects and likes to nest in cavities in buildings. Shrubs, seed-bearing plants, and good nesting sites provide it with shelter and food.

The kestrel is a common resident and migratory bird in Denmark and can therefore be seen year-round. The kestrel lives, breeds, and hunts in open country with scattered vegetation, such as fields and meadows, as well as along roads. This bird of prey lays its eggs in cavities such as nest boxes and old crow’s nests, or in buildings and hedgerows.
