Our parrots love roasted pistachios. Aside from tasting great, pistachios have health benefits for parrots.
One of the biggest health benefits of pistachios is that they are high in protein.
For parrots, protein is an essential part of their diet. Not only is protein what helps parrots to form their feathers, but protein is also required to help birds manage their body temperatures.
For this reason, more protein is necessary during molting season when parrots lose their feathers (and protection from the cold). Generally speaking, the larger the parrot, the more protein they require.
