Each spring, huge flocks of blackbirds migrate north. The majority of the birds in the flocks tend to be Red-winged Blackbirds, Common Grackles, and European Starlings. But, if you look carefully, you might get luck and find some Rusty Blackbirds as well. The Rusty Blackbird has experienced significant declines recently. The Rusty Blackbird Working Group (RBWG) says that their population has declined by 85-95% in the last 40 years. Unfortunately, there isn’t much known about why they are declining. The RBWG is working to change that. In 2014 and 2015, they organized a Rusty Blackbird blitz to count this species during their migration. This effort has provided a much deeper look into the life of this species. You can now read about the results of this study here.
