Baby birds, or hatchlings, typically emerge from their eggs either with down or very few feathers, or even completely naked. Some birds, like ducks and chickens, have a layer of downy feathers at hatching. Others, like songbirds, may be almost entirely featherless.
Elaboration: Bluebird is a songbird so naked as a new born child.
Next question.

It's probably too big of a file to send but I'll try to do it in sections.
