According to the Cornell Lab of Ornithology:
"Rusty Blackbird is one of North America’s most rapidly declining species. The population has plunged an estimated 85-99 percent over the past forty years and scientists are completely puzzled as to what is the cause. They are relatively uncommon denizens of wooded swamps, breeding in the boreal forest and wintering in the eastern U.S. In winter, they travel in small flocks and are identified by their distinctive rusty feather edges and pallid yellow eyes."
Thanks for letting me share this rusty blackbird encounter with you, be well, and come back soon.
