| | The Birds of North America Online: Fox Sparrow |
 | | H, I: Songs of the Red Fox Sparrow, whether from Newfoundland (H) or Copper River drainage in Alaska (I), consist mostly of pure whistles, and each male tends to have a single song form. |
 | | In Alaska, Red forms also have song dialects; songs from Copper River drainage, for example, are different from those in rest of Alaska, and males from Copper River drainage do not respond to playback of songs from elsewhere, and vice versa. |
 | | If a male Red Fox Sparrow in Newfoundland has 2 songs, he alternates them, in A B A B A B format (Blacquiere 1979), though Red forms in Alaska with 2 types do not always alternate (L. Peyton unpubl.). |
