Which feature indicates that a spotted thrush observed is a Mistle Thrush rather than a Song Thrush?
Answer
Its spots are generally larger, rounder, and sparser, often not extending as high up the throat
The Mistle Thrush is identified as the largest of the three spotted thrushes discussed. Its plumage pattern, while spotted, differs significantly from the Song Thrush. Specifically, the Mistle Thrush typically displays spots that are larger and rounder compared to the sharper, V-shaped markings of the Song Thrush. Furthermore, a key differentiator is the spatial distribution of these spots; on the Mistle Thrush, the spotting frequently does not reach as high up the throat or upper breast area as it does on the Song Thrush, which often appears more heavily marked across the entire chest.
