This is one of the 3 times we found them doing this uncommon birdcall sound and behavior.
As on wikipedia (http://en.wikipedia.org/wiki/Guinea_pig) it indeed seems to be related to stress...
We have no idea what triggered it. The guard that makes the sound appears to be Queenie (see my other videos for the Brown Abyssinian red eyed pig who is shown newly born in the birth vid.) who is 3rd in rank in the 8ft cage and was hiding behind the colored house.
For me it's the first time I heard it.
My gf has heard it the other 2 times a few months back.
i had five and my mom gave 4 to my cuzn's snake and my friends dad ate the last one
