In the last few days we began our island wide Alcid (puffins, guillemots and razorbills) monitoring. This means we get a look at our first puffin and razorbill chicks! At the beginning of the season we searched within the rocks, ledges and debris around the edge of the island for burrows of Alcids. After marking their nests, we planned to return once the chicks hatched.

Alcids are burrow nesters, meaning they lay their eggs inside a tunnel or crack in the rocks or soil. This keeps the eggs and chicks safe from most predators and also keeps the temperature for incubation fairly steady. Puffins and razorbills put all their eggs in one basket (so to speak) and lay only one egg in their burrows, while guillemots lay two. It’s interesting to note that guillemot eggs and razorbill eggs are speckled white and puffin eggs are solid white. I wonder why that is?

While we were checking alcid burrows Jordan came across a beautiful find. A leach’s storm-petrel! (see above photo) These strange pelagic seabirds nest throughout Petit Manan in burrows dug into the soil and sod. At night we can hear their strange calls that sound a lot like giggling. They are truly mysterious and beautiful creatures!

With the season coming to a close we are saying goodbye to our field tech and friend Andrea. It’s been a great summer with all four of us here and we are sad to see her go. Andrea will be getting back to school this fall at Umaine where she is studying Zoology with a focus on seabirds. Good luck Andrea!
