Hudson River Park’s STEM Activity of the Week offers free online resources for students and families to learn about the Hudson River. With many learning opportunities moving to online and virtual platforms, we have started this series to share a hands-on activity that is a fun and engaging way to connect with the Hudson River.

Check back weekly for new lessons focused on Hudson River ecology, Park research and sustainability, and be sure to check out our previous activities.

STEM Activity of the Week

Bird Beak Buffet

Hudson River Park provides important habitat to over 100 species of birds that fly through the Park every year! This STEM Activity of the Week teaches students how each bird species has unique adaptations to help them get the food they need to survive with an interactive game we like to call Bird Beak Buffet. Students will discover how specific beak shapes are indicators of where, how and what a bird eats. The diversity of beak shapes within the park allows for so many species to thrive right here in our backyard.
