IPA: //nɪˈdɪfəgəs//
KK: /nɪˈdɪfəgəs/
Describing birds that leave their nest shortly after they are born.
The nidifugous chicks quickly ventured out of the nest to explore their surroundings.
Nidifugous → It is formed from "nidi-" (from Latin "nidus", meaning nest) and "fugous" (from Latin "fugere", meaning to flee or escape). The word describes animals that leave the nest shortly after hatching, thus fleeing from it.
Think of animals that 'flee' ('fugere') from their 'nest' ('nidus') shortly after they are born — that's why nidifugous refers to those that leave the nest.
