I have come to realise, I don't have all the answers, I don't even have all the questions yet... but I'm working on it. Blue jays make an almost screechy noise similar to crows .

Can sharks hear a hum when something yummy is around? Sharks have keen hearing, a huge advantage in the ocean since sound travels both farther and faster in water. On top of that, sharks can pick up on very low-pitched noises known as infrasounds. Many oceanic sounds fall into this frequency range â a perfect example is the noise fish make when they're in trouble. Sharks hear this noise and know where they can track down some easy prey. Scientific studies have proven that when sharks pick up on infrasonic sounds â often their first clue about the location of prey â they usually swim over to the source in a hurry.
