1. Courtship: The male parakeet will engage in courtship behaviour to attract the female. This may include singing, dancing, and displaying his feathers.
2. Mating: Once the female is receptive, the male will mount her and insert his cloaca into hers. The male will then transfer his sperm to the female's reproductive tract.
3. Fertilisation: The sperm will travel through the female's oviduct, where it will fertilise her eggs.
4. Egg-laying: The fertilised eggs will develop inside the female's body until they are ready to be laid. Parakeets typically lay between 4 and 8 eggs per clutch.
5. Incubation: The female parakeet will then incubate the eggs by sitting on them to keep them warm. Incubation typically lasts for around 18 days.
6. Hatching: After the incubation period, the eggs will hatch and the chicks will emerge. The chicks will be altricial, meaning that they are born helpless and rely on their parents for food and care.
7. Fledging: The chicks will grow and develop rapidly, and they will eventually fledge (leave the nest) when they are about 6 weeks old. At this point, they will be able to fly and feed themselves.
Parakeets are typically monogamous, meaning that they mate for life. They can begin breeding when they are about 1 year old, and they can produce multiple clutches of eggs per year.
