[MCF30]

I've been noticing a strange chirping/squealing noise coming from my engine. Almost sounds like a bird (short clip attached to the post).

Usually occurs when driving at slower speeds, at low RPMs (1-2k). Happens quite frequently too, as of late.

Any ideas of what this could possibly be, or suggestions for areas to inspect? No engine light or error codes currently.
