Red-winged Blackbirds
have quite the variety when it comes to their plumage and colors. Epaulet intensity and overall feather patterns are depending on their gender as well as their age, and I guess the individual bird too. This speckled specimen is a young adult male. He still shows some of the beautiful baby pattern but is growing into the black, glossy plumage of the adult males. Just what the goofball in the gif is showing off.
