Monster flock of mixed grackles and starlings above the marsh behind my house today. A friend said he'd seen lingering red-winged blackbirds among such flocks at this late date (#climatechange much?) but I didn't spot any. Raucous unoiled-gate squeaking, squealing and chattering (next vid in thread) until our resident pair of red-tailed hawks scared the whole flock off in a rushing, wing-dusting black cloud. #birding
