The Shama’s natural food in the wild is insects, which they find by foraging through the fallen leaves on the ground. If you are rehabbing one, you can give it a diet of boiled, dried legumes with egg yolk, tofu, as well as raw meat supplemented with egg-shell powder for calcium and a drop of coconut or olive oil for Vit. E. They also love live mealworms and crickets. These are very high in protein.
Shamas are exceptionally clean birds, they need a dish of water to bathe at least once a day.
