In the wild, birds of all kinds spend the day foraging and scratching for food. They reside in small social groups, use dust baths to for feather conditioning and nest build. Pigeon cages should be large enough to allow the birds to stretch and flap their wings, and perches are essential. Multiple levels of perches are better than a single perch, allowing the birds choice. In addition to perches, enrichment includes hanging items, especially those that make noise, and bright colored objects.Providing bedding also allows the birds a chance to forage, which is a time consuming appetitive behavior. Dietary enrichment includes a variety of nuts, fruits and insects. Birds also require grit for proper nutrition.Some sources suggest that background music can reduce stress, and the availability of nest building materials allows birds to engage in natural behaviors, which are important for reducing stress levels.
