“An Unexpected ‘Tern’ of Events”

This morning we went hiking around the northern coast of the island. We traveled with Lab Coordinator Bonnie Clarke and External Relations Coordinator Alexa Hilmer as they guided us on a two-hour tour. Bonnie focused specifically on the geology of the island, highlighting the fact that the island is mostly granite with portions of other strikingly visible igneous and metamorphic features (e.g. dikes).

In part two of the hike, Alexa continued our discussion of the American impressionist painter Childe Hassam. She brought prints of some of his paintings from Appledore and we had fun trying to find the specific location and the exact vantage points (lines of sight) where he sat to create his masterpieces. Even today, almost a hundred years later, we continue to be inspired by the same, ever-changing views of light on rocks and water.

One of our animal observations from the hike was that the gulls on the northern cliffs definitely seemed more anxious of humans than those nesting around the dorms and labs. We got to witness two gulls locking beaks in a heated battle for territory and dominance. It was neat to see up close some of the behaviors we had learned about the day before!

When hiking through the gull colony it is best to heed President Theodore Roosevelt’s policy — “speak softly and carry a big stick."

As the morning continued, we hiked south towards Smith’s Cove. This southernmost tip of the island contained some phenomenal evidence of both glacial movement as well as metamorphism within the granite. And (perhaps most importantly?), since the southern end of the island is not a nesting area for gulls, our team got to enjoy a momentary respite from the attack birds as we examined and discussed the rock formations.

After our great morning walk, we had the opportunity to hear from the REU (Research Experience for Undergraduate) student interns. In addition to two-week course offerings, undergraduate students also have the opportunity to apply for research intern positions that allow them to research for 10 weeks on the island. Some of the topics the 2018 interns are researching include: sea animals eating plastics; parasites that possibly influence green crab behavior; the effects of sound vibrations on hermit crabs; and seal populations and entanglements. We hope our students back home will have such amazing opportunities for themselves in the future!

After lunch and a seal identification crash course from Alexa, we were able to put our skills in identification to the test with a boat tour of neighboring Duck Island. Staying a safe (and federally-mandated) distance away we were able to practice distinguishing the different characteristics of the Harbor Seal and Gray Seal as we viewed them “hauled out” on the rocks and bobbing in the water near our boat!

The highlight of the day was our attempted visit to the tern colony on White Island. Last night, Dr. Liz Craig taught us about the Common, Roseate, and Arctic Terns; These three tern species are the subjects of conservation and restoration programs on the Isles of Shoals. We were prepared to visit the island via small inflatable rafts that required a water landing (our feet would get wet) and then we were going to explore what promised to be a loud and messy tern colony. Some of us were dressed better for this adventure than others.

Alas, It was not meant to be. We learned first hand what Eisenhower knew when he said: “Plans are worthless, but planning is everything.” The weather was not cooperating, so we did what teachers do best and improvised our plans. Liz (who is now everyone’s rockstar role model) captured a few baby terns and brought them to us on the boat, which was securely moored just off shore!* Can you imagine?! We got to participate in taking measurements and banding baby terns aboard the boat. We learned the importance of banding to help scientists follow bird flight patterns and better understand their nesting behaviors. Everyone had a “tern” to hold a baby chick and we all hope to “retern” again someday!

*Please note — no chicks were harmed during this quick, educational adventure. After being measured and banded, they were safely transported back to their nests on land.
