Observation details
At 8:20 a flock of all dark swifts appeared in the sky just above the waterfall. We could not believe our eyes! We counted and recounted and did not see any white on them. They were very playful chasing and diving after each other. Five disappeared while seven flew east of the waterfall area and then disappeared and reappeared in that area until around 8:50. At 8:50 we observed one of the swifts fly north across the road. Attached photos show the black coloration and squared off tail. One photo shows five black swifts in one frame but they are far away and fuzzy.
