Fresh strawberries are fine; my Sweetgirl loves her strawberries, Sweetboy will eat them a little but Greengirl and Batboy are not particularly interested. Princess, my conure will eat them if I hand feed her. Some fruits, those in the Rosaceae family, chreeys, apples, plums ets have cyanide in their seeds and they are toxic. Berry seeds are alright as are melon seeds (you often find pumkin seeds in the seed mixes) although I wouldn't give them fresh melon seeds. The seeds keets eat are acutally grains (seeds of grasses).
