There were Rusty Blackbirds at Spring Valley this afternoon. I observed
them at the feeders located at the parking lot for the boardwalk. That
was about 4:30.

Lee and all,
Mark your calendar and open a free eBird account

Hotspot
Blitz needs your help locating Rusty Blackbirds, January 30 to February
15,
2011!
Rusty Blackbirds are no longer common or abundant as many early
observers
noted. The species is in steep decline for reasons not fully understood.
The
most recent published estimate by leading investigators suggests an 88%
decline during the previous four decades (Greenberg et al, November 2010
Condor). Rusty Blackbirds winter in Ohio in small numbers compared to
populations found in primary winter range in the SE United States.
During Ohio cold spells when snow is on the ground, rusties appear at
feeders--a secondary foraging choice. They normally forage invertebrates
by
flipping leaves and debris in swamps and moist pools in woodlands.
Alternatively, they choose grains. We see them in corn stubble with
other
blackbirds if we scan flocks carefully.
to be continued...

I had a Rusty Blackbird scouting out the feeders today. I thought it was
a
cowbird until I looked though my binoculars and saw its light iris'. I
saw
another one around a week ago and then saw what I thought was a bunch of
cowbirds. Now I am wondering if they might have been Rusty Blackbirds.
Are
they very common?
