Rusty Blackbird is a North American species of high conservation concern. Since the 1960s its population has declined 85 to 99%. Causes of this trend are unknown at this time, but the scientific community suspects global climate change and habitat degradation/loss. The 2014 Rusty Blackbird Spring Migration Blitz is a citizen science effort to engage birders in seeking out "rusties" and to submit their observations on-line. Check out the link for details.
