Mourning doves are commonly seen sitting in our pine trees or searching on the ground for sunflower seeds that have fallen from the feeders. They often have favorite perches where they sit, and from which their distinctive coos can be heard. However, they are easily startled, and take off like a shot. Their initial flight produces a sharp whistling sound, followed by the gentle flutter of their soft wings.
Time, as he passes us, has a dove’s wing,
Unsoil’d, and swift, and of a silken sound.
~William Cowper
walking on a country road 
I love the sound of these birds. Sometimes they perch on the lines in great numbers along our road. A subtle reminder of their urban pigeon cousins.
Yes, I love to hear their soulful sound. I sometimes see them sitting on the lines too, but usually only in pairs. There must be more of them where you live.
When we first had our house I heard them and I thought it was a dog moaning…. thought my neighbour was keeping some poor dog on a chain! Soulful is a great word for the call!
they have soothing sounds……unlike Herons who only SCREECH!
I’m not sure I’ve ever heard a heron, and from your description, I’m not sure I want to. 🙂
they make more crocking noises than any other sound.The sound they make when you startle them is scary!

Not the sound you would expect from such a beautiful bird.
exactly! They look beautiful but sound ugly.
