Good evening everyone,

It has been a while since I have posted and I wanted to update you on what we have been doing here on Metinic. Yesterday we completed the Gulf of Maine Seabird Working Group (GOMSWG) Census! In other words, yesterday was the most exciting day of the season because we got to find out how many birds we have nesting on the island!

The GOMSWG census is completed by carefully walking across the entire colony, while counting every single nest found and the number of eggs in each nest. Every nest we find is marked with a popsicle stick. Doing this allows us to calculate our error after the census by comparing the number of marked nests (with popsicle sticks) to unmarked nests (without popsicle sticks). It is important to get an idea of how many nests were missed during the census to provide a more accurate estimate of birds nesting on the island.

While it may seem simple to walk around the island counting nests, in reality it requires great attention to detail, patience and cooperation among the whole group. The colony is divided into a grid system. This allows us to walk in a line across each grid, to insure we cover every inch of the colony. Terns also nest on cobble beaches where the eggs blend in with the rocks. (At times it feels like the most difficult game of ISpy ever played).

The terns do not appreciate us walking around their eggs and they make their presence known. It is impossible to get through the census without get pooped on or dive bombed by a tern at least once. To protect ourselves we wear rain coats or old shirts, and flags on our hats. To an outsider looking in we must look absolutely ridiculous, but I would rather wear a flag on my hat than get hit in the head by an angry tern (trust me – it hurts!).

In total we discovered that we have 831 nests (or pairs of terns). Therefore, we have approximately 1,662 birds inhabiting the island for the breeding season. It is hard to believe that by the beginning of August every single bird will have left the island to travel South to their wintering grounds!

Every day on Metinic is a new adventure – I am excited to see what the rest of the season holds!

All the best,

Mary

P.S. Chicks will be hatching soon – stayed tuned!
