I think the take-home point here is that it's really fun and exciting to go
outside at night and hear birds that are migrating overhead but we should use
extreme caution when trying to pin them down to species level. Although some
species have distinctive nocturnal flight calls, some (especially sparrows and
warblers) are so alike that even trying to ID them with sonogram equipment is
extremely difficult if not impossible. If it's this tough using high-tech
equipment, it should be obvious that making these identifications with just our
ears could lead to a lot of inaccuracy. There's nothing wrong with leaving chip
notes unidentified!
