<speciesfyi-glossary slug="precocial"></speciesfyi-glossary>Definition
Describing bird chicks that are relatively mature and mobile from hatching, capable of feeding themselves shortly after birth.
Detailed Explanation
Precocial species — ducks, shorebirds, ground-nesting gamebirds — invest heavily in large, yolk-rich eggs and have very short incubation periods relative to adult body size. Their chicks are covered in insulating down and can thermoregulate soon after hatching. This developmental strategy suits ground-nesting birds where nest predation risk is high and rapid departure from the nest is critical for chick survival.
