I live in the Kansas City area, and for the last few summers have heard a distinct songbird call but haven't been able to visually id the bird. The call is a 3-note call that sounds like a high recorder or penny whistle, and it's 3 pitches La------Sol-Mi Sometimes La--sol-fa mostly a minor 3rd. it's a very high clear song that's whistled- no 'words' associated with the call as far as I can tell. Can anyone direct me to what bird might be making this call? I'd like to find a picture of it so that I can start looking for it. Thanks!
