We had some sunny weather this past weekend and temperatures soared to the upper 40’s (about 8-9 degrees C). As I was walking through my local marshland park, I heard an approaching loud noise, and before I knew it the sky was full of blackbirds. I turned my camera skyward and snapped off a few shot.
From the photos, I can’t identify all of the types of birds, but there seems to be a mixture of Red-winged Blackbirds and grackles and maybe a few others. What I find most fascinating, though, is the variety of wing positions, sizes, and shapes that you can see. Unlike the geese that I see flying in beautiful V-shaped formations, these blackbirds seem to be utterly lacking in organization as they move from place to place.

Our mixed flocks have common grackles, red winged blackbirds, brown-headed cowbirds and occasionally rusty blackbirds (call sounds like rusty wheel.)
Disorganized chaos, systematically captured.
Well said.
Reminds me of flocks of starlings, but they move like schools of fish in the air.
