Try to describe the call of a Black-faced Cuckoo-Shrike. I did once in my book
"Common City Birds". When I read it now I think it's awful!
The bird call descriptions in the field guides are so subjective. That's why we
have the apps.
According to my stats page, about a third of the visits to my website are
people listening to the sound.
Unfortunately, unaided , iPods and phones don't reproduce the very low or very
high frequencies very well - you need to use earphones or a good quality
speaker.
For most people, particularly males, what you hear is age related. I can only
hear now up to about 6 kHz. So much for grasswrens!
With human speech, I have difficulty with people who gabble - speak really fast
- I hear them OK but maybe the processor in my brain is also getting old.
Anybody know where to have neurons renovated??
