I was watching the antics of these Cowbirds (or Blackbirds?) in the bird bath when this odd yellow throated bird joined them for a rather energetic bath, lol. I've never seen this type of bird before, although different species of Cowbirds are quite common here in the large open pastures of Texas. Is he a mutation of some sort? I can't seem to find him in my bird fieldguide. Does anyone have any ideas? Thanks.... :)
