I can’t believe the season is more than halfway over! Yet there is still so much to observe and enjoy here on Petit Manan island. Recently we have begun to see the first of the arctic migrants, such as dowitchers and sandpipers. We have even seen some wandering passerines like mockingbirds, mourning doves and a fledgling robin. It says something about islands life when seeing a robin is a big surprise!
Unfortunately, the terns have had a rather bad stretch of luck. The combination of bad weather, predation and (seemingly) lack of food have had a huge impact on chick numbers. Parts of the island have done better then others. However, the colony doing okay. We even have a few fledglings flying around!
Most disconcerting, for us researchers, has been watching the great blacked-back gulls swooping in and picking off tern chicks. They are efficient predators. It is equal parts interesting and terrifying to see them hunting. Jill got a great photo of one taking an eider duckling, so you can see one in action below.
This weekend we have been joined by Bangor high-school student Max. He’s been an excellent addition to the crew and has been a great help with our research. Here he is examining a tern egg this evening.
