Does anybody have any knowledge about what is making these bird-like sounds at all hours of the day and night? We live across from the water taxi, and we’re hearing what starts out sounding like a bird chirping but then morphs into a car alarm like shrill… Last night continuous from 3:00 AM till around 8:00 AM – we’re getting rummy from the odd hours and sounds, but really can’t figure out what in the world this is! Anybody?
