Hello Ron, Bioacusticians
A large number of bird species especially hummingbirds have very high
frequencies, reaching up to 17-19 kHz.
Other examples which I studied are some finches in the genus Haplospiza and
Acanthidops whose higher frequencies are almost 13 kHz. If you want a copy of
this paper let me know

A review of sonograms published on the website www.xeno-canto.org for
brush-finches (Atlapets sp.) reveals many species with songs and calls in
the range of 8-11 kHz.

Every day, the hummingbird eats its own weight in food.
You may wonder how it weighs the food.
It doesn't. It just eats another hummingbird.
