  • Bat Monitoring with Maria Brown

    Tuesday, October 16, 2018

    Time: Meet at 6:15 pm at the parking area at Brookside County Park

    Join Maria Brown as we learn about bats with the help of bioacoustical monitoring that records the search call of the bats (sonar) in search of insects. Each bat species has a specific call that is not shared by other species and can be identified by the sonogram produced on the laptop screen. Watch the sonogram on the screen seconds before the bats fly over head. How many different species of bats will we observe? Come and find out!

  • Stop and Shop Card Fundraiser

    We have a easy way for you to support our Chapter that won’t cost you a penny. Stop and Shop has a fundraising program for non-profit organizations. They sell us gift cards at a discounted rate and we sell them at face value. So, a $50 gift card costs you $50. You would already be spending that at the grocery store anyway, and Great South Bay Audubon makes a profit.

    Use these gift cards for purchasing anything at Stop and Shop, or give as gifts. There is no limit to how many you can purchase, no expiration date and no fees. You don't have to spend it all at once; you carry a balance over on the card. It really is that simple. Gift cards are available in $25 and $50 increments.

    If you are interested in participating in this program, please click here for an order form, or purchase them at any of our General Membership meetings. As always, we appreciate you support.
