Why can you hear a skylark but never see it?

Question

i love the skylarks song and spend ages looking in the direction of where its sound is coming from but i can never spot it!

Answer 1

they sing when they are hovering very high up, and it is a loud song. if you have patience, scan the sky for a little dot, thats all you can see. you might spot one as it comes down, they stop singing and dive rapidly to the ground after the display.

Answer 2

Because of their brown feathers, its most likely that they are blending in with the enviornment, and there for you cant see them. also they have a very loud song, so if you hear it, you might be hearing it from far away
