The menu items under migration and perching/territorial behavior were rearranged, and a paragraph was added at the beginning of "Observing Migrating Butterflies" to distinguish between casual and more detailed ways of watching and reporting migrating butterflies.  In other words, you don't necessarily need to do everything on this page to report a sighting for the map - often a short note of which way you saw them flying is just fine.
