What do birds do during an eclipse? Much depends on the day cycle of the species. Is its diurnal, nocturnal or crepuscular?
As usual, Cornell Lab of Ornithology put out a great post on this subject.
- Diurnal aerial insectivores like Purple Martins dropped from the sky and roosted.
- Chimney Swifts that start circling their roost site at dusk began to do so.
- Crepuscular nighthawks were active.
- Nocturnal migrants dispersed.
More locally here in South Dakota, Dr. KC Jensen, of SDSU, reported the dawn chorus of many birds.
