I remember well my confusion the first time that someone identified a bird like this one as a female Red-winged Blackbird (Agelaius phoeniceus). “How can it be a Red-winged Blackbird, when it’s not black and doesn’t have red wings?” I naively asked.
I have learned a lot since that moment and have resigned myself to the reality that the names of birds and insects are often not descriptive (or apply only to one gender of the species).
Female Red-winged Blackbirds seem to forage for food in the underbrush most of the time and I have found it to be harder to get a good shot of females than the males, which seem to like to perch and pose prominently on the cattails. This female lifted her head for a brief moment, permitting me to get this shot, and then quickly returned to work.

It’s true-without a bird book I’d never know that this was a female red winged blackbird.
As usual a shot worth spending time to enjoy
Well done. There certainly are some confusing colourations on couples and then sometimes the juveniles are different yet.
