Goffin's Cockatoos are small-bodied cockatoos with surprisingly high metabolic demands. Their diet in the wild consists of seeds, nuts, fruits, berries, blossoms, and insects, which means a captive diet must replicate that variety to prevent nutritional deficiencies. A seed-only diet is one of the most common mistakes owners make, and it leads to obesity, fatty liver disease, and dangerously low levels of vitamin A and calcium over time.
The foundation of a Goffin's diet should be a high-quality formulated pellet, which ensures balanced macro and micronutrient intake without the selective feeding that seed mixes encourage. Pellets should make up roughly 60 to 70 percent of the daily diet, with the remainder composed of fresh vegetables, fruits, and occasional nuts or seeds offered as enrichment rather than staples.
Calcium and vitamin A deserve special attention in cockatoo nutrition. Deficiencies in these nutrients are among the most frequently diagnosed dietary problems in companion parrots. Dark leafy greens, sweet potatoes, carrots, and red peppers are excellent whole-food sources of vitamin A, while cuttlebone and mineral blocks can supplement calcium intake. Owners should work with an avian veterinarian to determine whether additional supplementation is needed based on bloodwork results.
Because Goffin's Cockatoos are prone to weight gain despite their small size, portion control matters. An adult Goffin's typically needs about 30 to 40 grams of pellets per day, supplemented with roughly a quarter cup of fresh produce. Monitoring body weight weekly with a gram scale helps catch gradual changes before they become health problems.
