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  

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??
