I belong to couple of groups on Facebook that are all about birds and in a couple of those groups people ask for bird identification from images they have taken, there are a few groups that are strictly about identification.
Female Red-winged Blackbirds seem to be the birds that are most often misidentified probably because they look so different from the males. Red-winged Blackbirds are sexually dimorphic.
the condition in which the males and females in a species are morphologically different, as with many birds.
I have seen novices identify female Red-winged Blackbirds as Seaside Sparrows, young Varied Thrushes, “some kind of sparrow” and many other misidentifications. In one group alone I think they are misidentified about 10 to 12 times a day.
Bill shape, bill size, body size, shape, color, plumage patterns, leg color, leg length and eye color can all be used as keys to identification in Red-winged Blackbirds and all other birds.
I wanted to include a photo of a male Red-winged Blackbird for comparison, the males and females really do not look alike in color or plumage, but they do have the same shape, the same bill size and shape, the same legs and eye color.
Bird identification can be complicated and for novices I always recommend purchasing field guides or downloading bird guide apps to their phones especially if they are serious about photographing birds. The guides really help but actually studying the guides is more helpful.
Life is good.
