Ever wonder what we do in the field? Check out this video of Bertrand Chair, Joan Walsh, marking Roseate Tern nests on Great Gull Island, NY. Jeff Collins, Director of Conservation Science at Mass Audubon, asked Joan to share what a day in the field looks like on Great Gull Island. Joan has worked on Great Gull Island off and on for 39 years. The island is home to 18,000 Common Terns and 3,000 federally endangered Roseate Terns.
When she reaches a Roseate Tern nest box, if there is a nest, she marks it with GPS coordinates and records data on eggs and nestlings. Roseate Terns prefer to nest under vegetation or in man-made nest boxes. The work seen in this video was part of Joan’s 5-day effort to mark nests.
Important: It is illegal to approach or disturb a nest without a permit. Joan works under a permit to research Roseate Terns and Common Terns.
*Video footage was sped up when Joan is doing the nest box marking to fit more content in 1 minute. Joan is not that speedy!
