Taken at the Midewin National Tallgrass Prairie in Wilmington, Illinois.
These dickcissels seem to take exception to the lack of avian representation on this sign.
Dickcissels are a sparrow-like bird of the prairie grasslands of the United States. Dickcissels congregate in huge flocks in migration and on their tropical grassland wintering grounds. The breeding male is colored like a tiny meadowlark, with a black “V” on a yellow chest.
