One of the hardest things to do with parrots can be getting them to eat a better diet. Parrots are naturally suspicious of new items as a safety mechanism to protect them from potentially deadly objects. If they have never been shown that a food is not only edible but delicious, most will naturally avoid it. There are many ways to try and get them to try new foods, and I am always on the look-out for new ideas, even if I am not currently trying to switch anyone's diet.
Watching Claudia recently, as I was getting treats out to fill her foraging toys, I realized something very important: Claudia will eat anything if it comes from a prized treat jar. Anything. As soon as she sees or hears a jar she will start pinning her eyes and begging to be picked up, with her foot out and ready! She is not normally a lover of new foods, so I usually have to offer them for a few days, carefully showing her each morning how to eat them, and how wonderful I think they are, before she will fall in love with them. Therefore, the idea that I can get her to eat something simply by placing it in the dried pea jar and pretending it is the best kept secret in the world of treats is quite useful!
