this is a corncrake chick, also commonly misidentified as a rail’s chick! crow babies are MUCH uglier…
putrid little man
baby boy
Above, a precocial (mobile at birth, cute fluffball) baby, like chickens and ducks have. They’re able to run around and pick up food and act like birds. You see this in ground-dwelling species like shorebirds, where they can run after the adult. Downside, they need to be incubated for comparatively long times in the egg.
Below, an altricial (nakey and helpless at birth, terrible ugly beast) baby, like most songbirds have. Baby crows start out nakey, floppy little sock-puppet things that can’t really move and have to have food stuffed down their throat by adults. They hatch from the egg much sooner, and can be more easily contained in a nest, but are useless on their own.
