The tri-colored blackbird is a species that is in decline. Lack of habitat is the basis for most declines. I’ve heard that there are ongoing efforts to reverse the trend, but I don’t know if they are effective.
On a few occasions I’ve had a chance to photograph them. Here are two photos of tri-colored and another photo of a red-winged blackbird. They are very similar in appearance.
