Budgerigars are among the world's most commonly kept pet birds, but their welfare needs are frequently misunderstood, with many birds suffering from inadequate space, social isolation, and poor diet.
Budgerigar welfare in captivity is frequently compromised by housing that fails to meet basic needs. Tiny cages sold in pet shops are typically far too small for the flight exercise budgerigars require. Solitary budgerigars are deprived of the constant social interaction they need, leading to psychological distress expressed through feather-plucking, rocking, and bar-chewing. Seed-only diets cause nutritional deficiencies, particularly vitamin A deficiency causing respiratory and eye problems. Budgerigars held alone but with mirror toys experience confused social behaviour. Keeping budgerigars in minimum pairs in large aviaries with enrichment is the welfare-positive approach.
