Monarch Butterfly Migration Explorer

There has been a huge drop in the number of Monarch butterflies that made it to Canada this year. Let's see if we can see the difference using Flickr photos.

The data isn't perfect, for example Flickr itself has had ups & downs over the past few years, and the number of digital cameras that we've been carrying has been changing quickly, but this should give us some idea of what's going on.

There are still things I'd like to add if time allows:
