A bird that treats branches like open mics and never checks its watch.

means A bird species known for producing melodic, complex vocal songs — and by extension, a person with a lovely singing voice.

from Simple compound of 'song' + 'bird,' first describing birds of the order Passeriformes (specifically the suborder Oscines, literally 'songbirds' in taxonomy) whose vocal organs let them produce true melodic song rather than mere calls. English speakers later stretched the word affectionately onto human singers — a cousin of other animal-voice metaphors like 'nightingale' used for a sweet-voiced person.
