Budgies don't like new things, or at least, while they are still "new". In early days, I would often introduce greens, or strawberries, or a new toy, and the budgies would ignore, or more likely, avoid then new item. I would conclude they didn't like it and remove it. Now I realize that it can take days, weeks, or even months for budgies to warm up to something novel. Once they do, though, they can go wild with their enjoyment. Budgies are step functions, when it comes to acceptance of something. For example, I had to put strawberries in the cage for several days (after a day in the cage, they would be replaced with new ones) until the budgies would nibble on them. Now, they will often simply devour them (and make a bit of a mess flinging them, as well). Ditto with various types of greens, and treats. Magoo is by far the most adventurous, followed by Sutcliffe. This may be another "flock leader" behavior of males. If you have budgies, I recommend being patient in introducing new foods. Put the food in every day, and remove it when it wilts/gets old, and just do it regularly. It could take a week, or more, but the budgies will try it eventually and if it is greens or strawberries, probably like it. And if it is a toy, they will enjoy banging on it, when they don't get their way, after a few months. At least, this latter was true for Mary ann.
