Watching spring approach

Journey North is a project that tracks online the northward appearance of regular spring events. Among the phenomena tracked are the arrival of robins, the emergence and blooming of the first tulips, and the monarch butterfly migration. Scientists in the field are children in classrooms across the country, who report their sightings online to Journey North, which enters the data into their mapping software. As of today, tulips are reported emerging from school plantings as far north as Concord, MA.
