Southern Illinois: Shawnee National Forest
June 3, 6:21 a.m.
Sunrise at 5:33 a.m.
From a utility wire directly overhead, a dickcissel sings his version of the local dialect: dick dick ciss-ciss-ciss-ciss. For variety, sometimes it's only one dick, sometimes only three ciss, but that's about the extent of how much he varies his song. His song is typical of this dialect.
Here's a summary of the dickcissel dialects you can listen to:
Illinois, Shawnee National Forest, one male: IL-107
Indigo bunting, American crow, summer tanager, field sparrow.
