Almost every time I observe a Catbird or Mockingbird, Merlin finds both and a Thrasher too. I am not sure how it would do with a real Thrasher as I have not found one yet. Merlin is a great tool but you can not list a bird just because Merlin says so. Pat Tamborra, Salem Sent from my Verizon, Samsung Galaxy smartphone Get Outlook for Android<https://aka.ms/AAb9ysg>
