Who are the first birds to show up at the first signs of spring? Join us at Grass River Natural Area on Saturday, March 17th, at 9 am for the first walk of the series as we look and listen for these first birds of spring. Grass River is a birding hotspot and a great place to learn your birds. We will also learn how to use eBird to record our findings. Bring your own binoculars or use a pair of ours. There is limited space for this program. Please pre-register.
