IPA: /nɒnˈbriːdɪŋ/
KK: /nɑnˈbridɪŋ/
Referring to animals or plants that are not reproducing or are not involved in the process of reproduction.
The nonbreeding season is a time when many animals do not mate.
Nonbreeding → It is formed from "non-" (meaning not) and "breeding" (from Old English "bredan", meaning to bring forth or produce). The word "nonbreeding" refers to the state of not producing offspring or not engaging in reproduction.
Think of 'not' ('non-') producing or bringing forth ('breeding') — that's why nonbreeding means not engaging in reproduction.
