Birds are very intellegent animals, they can sing, dance and play with you when given the right kind of attention. They are also sensitive creatures that will recognize patterns in your behavior, often learning to anticipate habits or tendancies -sometimes before you notice them yourself! They are also great for watching as they play; parakeets have a routine of thier own that can be seen when healthy including preening thier feathers, being alert and active during the day, socializing, usually a mid-day nap or two and foraging will often lead thier daily lives. They are a naturally sociable species and can in some cases establish a pecking order (or be territorial of thier belongings twards other budgies) but with adjustments to thier environment or enclosure it isn't usually a major issue.
Toys, along with maintaining thier supply of fresh water and food should always be accounted for as well as a clean space and suitable ventilation is also key must-haves for keeping birds. During the day they need appropriete lighting and stimulation and for bed time they can have a cage cover and quiet time.
Most parakeets enjoy having your attention and being talked to in a calm and gentle tone. With a safe space to fly and perch, parakeets will benifit from free flight time, as do many caged birds. You're setting a good goal if you work twards providing free flight time on a daily basis.
