Mourning Doves

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
