Spring Migration in St. Louis' Forest Park
For 20 years, my friend Randy Korotev kept extensive notes on birds in Forest Park on the west edge of Saint Louis MO. His article, "Counting Warblers; A Timetable for the Spring Songbird Migration Through Saint Louis," with original data is available online or as a PDF. Click on "Bird and Birding Information," then "Timetable for Spring Migration."
I decided to illustrate his data using TimeToast, arbitrarily choosing the year 2009. Just hover the mouse over the balloons to display them. Click once to see text, links, photo, and photo credit. To extend the timeline and see the dates farther apart, slide the control on the bottom in toward the center. In my other set of pajamas, I teach computer at an elementary school. I made a tutorial video for TimeToast if you're interested. Please feel free to use my "Peak Migration TimeToast" for non-commercial purposes.
In addition to this amazing feat of record-keeping and persistence, Randy is a true Renaissance man. I interviewed him about moon rocks last summer and returned to the moon rock story last December. Visit him at his lunar meteorite website!
