The exact nutritional requirements for most species of birds are still unknown. The exceptions are birds raised for food or other products, such as poultry, ostriches, and pheasants. Avian diets for many species are extrapolated from the Nutrient Requirements of Poultry, published by the NRC.

When working with large zoological collections containing disparate species, individuals should work as a team to manage nutrition for multiple species. The keepers’ experience regarding birds’ habits and preferences is essential, combined with input from the curator, veterinarian, and outside nutritional consultants. Input from other institutions where a given species has a history of longevity and successful reproduction can be invaluable. In large collections, decreasing waste, spoilage, overfeeding, and excessively time-consuming diet preparation must be considered, along with improving birds’ nutritional intake.
