Do bird songs have frequencies higher than humans can hear?
A. The frequency range of human hearing is often reported to be between 20 and 20,000 Hz. As we grow older, we all tend to lose the ability to hear higher frequencies. Many bird songs have frequency ranges between 1,000 Hz and 8,000 Hz, which places them in the sweet spot of human hearing. On the high end, many warblers, sparrows, waxwings, kinglets, and a number of other birds produce sounds that reach 8,000 Hz and beyond.
