Here's a couple of photos to help forum member in identifying bluegill by sex.
This fish was caught yesterday at my all-male bluegill pond. Note the extremely good body condition due to lack of competition and availability of artificial feed. This fish has a large ear flap or ear tab, black in color and extended posteriorly (tailward). Vivid coloration and burgundy colors on breast. Lots of black tips on scales.

Holding a redear sunfish is like running with scissors.
