Cage Requirements for Finches

Finches are popular pet birds that come in a variety of colors and types. They thrive in flocks in large aviaries but can also be kept as caged birds indoors. Caged finches are happiest when kept in same-sex pairs. They require a cage large enough for them to fly around and places to perch. The responsible finch keeper will clean his cages weekly to avoid disease.

Size

Finches love to fly and prefer a cage that is long rather than tall. For two finches, the length of the cage should be at least 30 inches, but larger is always better. The bars of the cage should be no larger that a half-inch apart. Otherwise, the finch could escape. For more than two finches, consider a walk-in aviary. These birds establish a hierarchy and need plenty of space to avoid bullying.

Perches and Accessories

Avoid dowel perches and sandpaper-covered perches, which are bad for finch feet. Instead, opt for non-toxic hardwood branches of varying widths to provide exercise for the birds' feet. The perches will need to be replaced when they become covered in droppings. Put in at least two perches, on separate ends of the cage, to encourage flying. Finches also often like swings. Keep perches and swings out of flight paths and not over food and water dishes. Avoid wood chips for the floors, because they often cause respiratory issues. Instead, simply line the cage with newspaper. Sturdy stainless steel or non-toxic plastic food and water dishes are a must. Some finches like to spend the night in a nest, and small basket nests are sold at many pet stores. If you have both male and female finches, they will breed in the nest, so check frequently for eggs. Beads, mirrors and other shiny objects may attract finches, and some enjoy climbing ladders. They may enjoy a shallow water dish for bathing.

Lighting and Placement

Place the finches' cage at eye level on a sturdy surface in a room that receives plenty of natural light but away from direct sunlight or drafts. If there is not much natural light in the room, meet the birds' light requirements with a full-spectrum light with a timer, recreating natural sunlight and darkness patterns.
