Rusty Blackbirds

Today six Rusty Blackbirds were observed and digiscoped on Old Connecticut River Road in Springfield, Vermont.  These were in a flock of 10+ Red-winged Blackbirds and four Common Grackles.

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.
