The Earth Week Birding Classic was held from April 15 to 25, 2021. The goal of the event is for teams in seven different categories to count as many species of birds as possible over a 24-hour period any time during the week beginning on Apr 15 at noon and ending at noon on April 25. This non-profit event is co-sponsored by the Environmental Studies program at Penn State Altoona and Juniata Valley Audubon Society.
