Since penguins hunt in the ocean, the babies must rely on their parents for food until eventually, the young bird is old enough to molt (when a penguin sheds feathers on its body and is restored with new ones) and the down is replaced with adult feathers. They do not stay in the nest, and include ducks, chickens, and geese.
If this ever comes to fruition, we would be the silliest looking penguin there ever was!https://web.stanford.edu/group/stanfordbirds/text/essays/Precocial_and_Altricial.htmlhttp://www.paulnoll.com/Oregon/Birds/feather-down.htmlJan R.

Taylor, Thermal Insulation of the Down and Feathers of Pygoscelid Penguin Chicks and the Unique Properties of Penguin Feathers, , Volume 103, Issue 1, January 1986, Pages 160–168, Avian Growth and Development: Evolution within the Altricial-Precocial Spectrumbooks.google.com/books?id=A0HB7Mq4lOYC&printsec=frontcover#v=onepage&q&f=false.Williams, CL, Hagelin, JC, & Kooyman, GL. They will NOT reject them if you touch them. ?” Would you describe it as a “floof-ball”? While similar to precocial birds in that they are both born with feathering, a precocial baby will be able to fend for themselves or follow their parents around and to learn how to hunt within the first few weeks of life. For penguins, the down has a gray or brown coloration. Additionally, body down helps with a penguin’s movement in water. Altricial animals produce large number of offspring with a relatively small energetic investment in each one; therefore, the offspring are born pretty weak and many will probably die. As a wildlife rehabiber, we are deeply saddened when good-hearted people mistakenly think that they are saving a fledgling who is actually being cared for by its parents. When young individuals of altricial species are too immature to be tested before the acquisition of significant experience in the domain of interest, often precocial species are convenient models. Altricial: Precocial: Behavior: Stay in the nest; Unable to move; They depend entirely on their parents; The majority is capable of perching on branches; They leave the nest after 1-2 days; Able to walk and swim; They can find their food but they are accompanied by their parents; Mostly restricted to the ground; Eyes at hatching: Closed eyes. Precocial birds hatch with their eyes open and are covered with downy feathers that are soon replaced by adult-type feathers. Let us know what you think. Please call them and send a photo ASAP if you find a hatchling or nestling with pin feathers.People can truly save wildlife by keeping their cats inside during nesting season.
On the other hand, as an altricial baby gets older, the down feathering thickens, and they are able to self-thermoregulate, but natal down is not waterproof, so until the penguin’s body is mostly covered in contour feathers that can be waterproofed, the bird cannot go into the water or it could risk drowning and hypothermia. If the parents are not around, they may be caring for the other siblings.If the young bird has a well-developed cover of down and walks and swims well, it is most likely that it is a precocial bird and needs to be left alone.Whether on the ground or in branches, altricial and precocial birds make persistent calls with the intention of alerting their parents about their location. http://dx.doi.org/10.1098/rspb.2015.2033 Retrieved from https://escholarship.org/uc/item/0xs4w8d0By clicking send you agree to receive the latest news about penguins. I was bitten by a friend’s house-cat saving it as it was attacked by a feral cat. By contrast, species whose young are immediately or quickly mobile are called precocial
