Yes, a cockatiel (Nymphicus hollandicus) is a type of cockatoo. Cockatiels are often referred to as "miniature cockatoos" due to their smaller size and similar physical characteristics to other members of the cockatoo family. However, they have distinct features that set them apart from other cockatoos, such as their distinct yellow crest and their quieter, more docile nature.
The cost of a cockatiel can vary depending on several factors such as the bird's age, sex, color mutation, and where you are purchasing it from. On average, a pet store may sell a young, hand-tamed cockatiel for around $100 to $200 USD. However, breeders may charge more for certain color mutations or breeding pairs. Additionally, there may be additional costs associated with purchasing a cockatiel such as a cage, food, toys, and vet visits. It's important to research and budget for these additional costs before bringing a cockatiel home.
