Budgerigars (Melopsittacus undulatus), commonly known as budgies, can make wonderful pets. They are generally inquisitive, social birds that are relatively easy to keep.
There are many colour varieties available, with the green colouration being the most common in wild birds. Mature males generally have a blue cere (the cere is the skin structure around the nose and above the upper beak), and females usually have a brown cere.
