Once or twice per week I give my Senegal a quarter-sized piece of sweet potati chip (Brand is Terachips and they have an unsalted version). There is still the fat but it is canola oil. They are one if the "treats" she is allowed to have (others are small pieces of organic unsalted walnuts, pecans, almond, or hazelnuts) mostly when I need to bribe her to go in her cage. When I tell her "it is time for me to go to work" she responds "treat?" and willingly goes in for a small piec3 of treat.
Also my family and I enjoyed Kili's Doritos commercial as we do all her videos. Michael does an amazing job and is providing a much needed educational service for companion bird owners . Although the Doritos video is cute and entertaining it does emphasize an important point - protective eyewear should always be worn around birds. Any time my flighted bird is out (which is a great deal of the time I am home) I make sure to wear glasses or safety goggles over contacts. I keep safety goggles near her cage for petsitters and guests. Whether it is an accidental attempt to prevent a fall or an intentional lunge, a birds beak really can severely damage an eye and could blind someone. It is not the bird's fault because they are a wild creature behaving instinctually - humans just need to think about this possibility and be properly protected.
