Here in georgia we had about 95+ coverage of the sun, bird activity wasn't that notable, shadows seemed a little more vivid, but it didn't last long enough for me to notice cricket activity, maybe It would have been different if I'd have taken the glasses off[joke].I was a few feet from the hummer feeder, and about 12 ft from the bird feeder. As far as the light was concerned, I anticapated a bit more more dimming, .I know if I had driven any distance for the same results, I'd have been underwhelmed.
