If you want your Caique to be your best friend for life, then you’ll need to include blackberries in your bird’s menu. They adore seasonal fruits like raspberries and blackberries, but just because they love these soft fruits it doesn’t mean that the same fruits feel the same way about the Caique. Blackberries can have an unfortunate effect on the digestive system of a Caique and can change the color of their droppings from bright white to midnight black.
It isn’t anything that you should, or need to worry about though, as the discoloration doesn’t, and won’t have any impact on the wellbeing of your Caique, but it can be a little scary the first time you see it. So, as long as you’re ready and prepared for the inevitable outcome, you should definitely add blackberries, when they come into season, to your Caiques diet.
