It’s springtime in the Northern Hemisphere, and one of nature’s greatest spectacles is unfolding: the migration of billions of birds to their breeding grounds.

There was nowhere to go, nothing to do. I started watching the birds in my yard out of sheer boredom, using the Merlin bird identification app from the Cornell Lab of Ornithology to figure out which species were visiting my feeder and recording my observations in the eBird online…
