Many species of birds on Antelope Island State Park are pigging out on wild sunflower seeds at this time of the year including Red-winged Blackbirds.
The plumage of male juvenile Red-winged Blackbirds is highly variable during their first year, some of the young blackbirds can look like females and some can look more like adult males.
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 .
Even though it is late May there are still male Red-winged Blackbirds displaying and singing their little hearts out here in northern Utah and that is what this male blackbird was doing.
