[Tweeters] Black Swifts hunt at up to 4000 meters high under a full moon and: “Black swifts descended rapidly during lunar eclipse -- ScienceDaily”

[Robert O'Brien]

This of course is the Eurasian Swift, Apus apus not the North American
Black Swift that we have here on the West Coast. But who knows? It had
already been established that Apus apus can stay aloft for long periods of
time . But the time reported in this study is astounding.  Bob OBrien
