To distinguish between the songs of the Summer Tanager and the Scarlet Tanager in mixed-species flocks during spring migration in the southeastern United States, consider the following methodology:

  1. Song Structure and Rhythm:

    • Summer Tanager: Their song is typically longer, more musical, and has a sweeter, flowing quality. It often features descending phrases and a more consistent rhythm.
    • Scarlet Tanager: The song is a series of short, robin-like phrases with a more choppy or broken rhythm.

  2. Pitch and Tone:

    • Summer Tanagers tend to have a higher-pitched, sweeter tone.
    • Scarlet Tanagers may have a slightly lower pitch with a harsher quality.

  3. Phrases and Syllables:

    • Listen for the number of syllables and unique phrases. Summer Tanagers may have more complex sequences, while Scarlet Tanagers might repeat shorter, distinct phrases.

  4. Visual Identification:

    • If possible, observe the birds. Male Summer Tanagers are entirely red, while male Scarlet Tanagers have a red body with black wings and tail.

  5. Audio Resources:

    • Use audio recordings or birding apps to compare songs in real-time, aiding in identification based on recorded characteristics.

By focusing on these elements—song structure, pitch, unique phrases, and visual cues—you can effectively differentiate between the two species.
