Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs are the bird sounds that are melodious to the human ear. In ornithology and birding, (relatively complex) songs are distinguished by function from (relatively simple) calls.

Famous quotes containing the word bird:
“but as an Eagle
His cloudless thunderbolted on thir heads.
So vertue giv’n for lost,
Deprest, and overthrown, as seem’d,
Like that self-begott’n bird
In the Arabian woods embost,
That no second knows nor third,
And lay e’re while a Holocaust,
From out her ashie womb now teem’d
Revives, reflourishes, then vigorous most
When most unactive deem’d,
And though her body die, her fame survives,
A secular bird ages of lives.”
—John Milton (1608–1674)
