Red Winged Blackbird, Agelaius phoeniceus. Common across North America, frequently found in marsh, wetland, or pond habitats. Some migrate to Canada for breeding and some migrate to western Mexico for winters, most generally staying throughout the U.S. all year. There are around 22 recognized subspecies. Many studies have been done on this species, looking at their ecological impact. Red-Winged Blackbirds are highly abundant, flocks reaching up to many millions strong. The colorful wing patches on the males are important for territory defense and mate attraction. Though preferring watery habitats, they can be found in nearly any habitat. They are also opportunistic omnivores, meaning they will eat pretty much anything, but prefer seeds and insects. Being sexually dimorphic, the males have a distinct plumage while the females are more cryptically colored and can sometimes be difficult to identify.
