It is necessary to understand a Cockatiel behavior to keep them happy and content for life. They can be trained to imitate simple words and sentences. They can even whistle softly. These things really make them adorable. Tame cockatiels often love to do things like take showers with you and wolf-whistle.
Proper hygiene would avert common diseases like runny nose, gout or E-coli from your Cockatiel pet. Although hardy birds, but the Budgies are prone to accidents owing to their small size. They are also very sensitive to their environment; therefore, hygiene and cleanliness must be maintained. Water should be changed everyday and food should not be kept over 3 hours in the cage. Clean their cage with anti-bacterial solutions from time to time.
