When Mom just arrived, and the chicks talked to her a bit (so nice to hear baby squawking again) I could've sworn that one of the chick's squawks ended with a bit of a squonk
I think that the mic has a tendency to distort sounds (there's an intermittent sound now, a high-pitched sound, that I've heard before on this site)
Just happened again, a chick squawking, ending in a squonk
