The lists are organized according to the date sightings were REPORTED. (If an observer waits to report a sighting it will appear on a later list.) All data reported--incl. First SEEN, Wave SEEN, Other Observations--can be found in the data archives. (The archives include raw data, exactly as reported from the field. Journey North staff review raw data, edit as needed, then publish the weekly data summaries.) Facebook Pinterest Twitter © 1997 – 2019 Journey North. All rights reserved.
