1. Size: Baby cockatoos are relatively small compared to adult birds of their species. Their size varies depending on the specific cockatoo species, but they typically measure a few inches in length when they first hatch.
2. Color: Baby cockatoos usually have a different coloration compared to their adult counterparts. They often have duller or paler feathers, and they may lack the vibrant colors that adults display. Some baby cockatoos have mottled or brownish plumage that provides camouflage in the nest.
3. Featherless: When they first hatch, baby cockatoos are typically altricial, meaning they are born without feathers. Their skin may be pink or gray, and they may have sparse down feathers on certain areas of their body, such as the head or wings. As they grow, they gradually develop feathers that replace the down.
4. Head: The head of a baby cockatoo is relatively large compared to its body. Their eyes are usually dark, and they may have a slightly disproportionately large beak. The beak is typically a lighter color compared to adult cockatoos, and it may be yellowish or pinkish.
5. Feet and Legs: Baby cockatoos have weak feet and legs when they first hatch, as they rely on their parents for care and support. Their feet may be pink or gray, and their claws are usually small and not fully developed.
6. Behavior: Baby cockatoos are entirely dependent on their parents for food and protection. They spend most of their time in the nest, where they are cared for by both parents. They beg for food by making vocalizations and fluttering their wings. As they grow and develop, they gradually become more active and independent.
It's important to note that the specific appearance of baby cockatoos can vary depending on the species and individual bird. As they grow and mature, they undergo changes in their coloration and physical features until they reach adulthood.
