Down through the ages, as I've done field recordings in Missouri, I've become used to most of them having a comfortable mix of frogs, crickets and other critters mixed with the chatter of hundreds of avian breeds. January, however, saw a noisy migration of Grackles and the sheer excess of them in our yard and trees was such that I HAD to record a slice of the soundtrack. Being the middle of winter, the birds are unadulterated by any other sound. Not necessarily a good thing!
The finished recording was frightening and disturbing in it's intensity and complexity; it reminds me of the work done by Remi Gassman for Alfred Hitchcock's The Birds, more than anything else. The pattern of massing/the sound growing by the moment/and then all flying off loudly in one rush of thousands of wings is dramatic and chilling. Here is a slice of the full recording. Enjoy the sounds- you've been warned, though!
