What animal sounds do you like to hear?

Okay they may not have the power of speech or the ability to punctuate XD, but nevertheless animals do have many weird & wonderful vocals. From birds singing to elephants trumpeting, there’s a lot out there. I love the sound a horse makes, a whinny if you will. A lions roar has the hairs on the back of my neck standing to attention. There’s a bird, I think it’s the secretary bird, which mimics whatever sound it hears. Spectacularly impressive stuff right there. So, how about you?
