VOLUNTEER AS A HORSESHOE CRAB MONITOR
Signups for 2024 are now closed. To receive email notifications about horseshoe crab monitoring volunteer opportunities in 2025, or any of our other volunteer opportunities, subscribe to our eGret newsletter.
Horseshoe crab monitoring is a fun and easy volunteer activity, and an important way to contribute to scientific research and bird protection. Volunteers join NYC Audubon on beaches in Jamaica Bay on 12 nights in May and June to count, measure, and tag Atlantic horseshoe crabs, the eggs of which are a critical food source for migrating shorebirds like the Red Knot. NYC Audubon coordinates monitoring efforts at two beaches, Plumb Beach in Brooklyn (split into a east and a west side) and Big Egg Marsh in Queens, as part of a larger Horseshoe Crab Monitoring Network. Monitoring dates are chosen based on the full and new moons. Scroll down for more details about NYC Audubon's monitoring sites and the 2024 monitoring dates.

IMPORTANT NOTES
GROUPS AND FAMILIES WELCOME!
Kids are welcome, but we require that minors under 18 years old be accompanied by a parent or guardian. Please note that it will be dark by the end of the shift, and there will be some wading in the water.
ACCESSIBILITY
Participation in this project requires walking about one mile on the beach and other uneven terrain, including wading through water of up to 10” deep. Note that it will be dark by the end of the shift, and while no specialized equipment is needed, you will need to bring water shoes/shoes that can get wet, and a headlamp.
TRANSPORTATION
Volunteers are responsible for their own transportation to the monitoring sites. Public transportation by bus and subway is limited, so be sure to carefully check availability or arrange your own way there. NYC Audubon does not arrange carpools but may be able to facilitate connections with other volunteers. Once you are assigned to a shift date and location, feel free to contact your fellow volunteers to share transportation.
GEAR AND CLOTHING
For your volunteer shifts, you’ll need to bring with you:
- Clothing that you don't mind getting wet
- Water shoes, old sneakers, or tall rubber rain boots
- Warm layer and windbreaker (it’s always a little cooler at the beach)
- Foul-weather gear in case of rain
- Change of pants, socks, and shoes
- Water bottle to rinse off your shoes
- Headlights with extra batteries (you’ll need your hands, so bring a headlamp, not a flashlight)
- Insect repellent
