Common Tern on flagpole

Common Tern on flagpole

Another year on PMI! After two weeks of cold weather and high winds the terns have finally started to nest. Maybe not in the numbers that we are used to but it’s still early enough for more terns to arrive and settle in for the nesting season. The Alcids on PMI don’t seem to waste any time, Atlantic Puffins and Razorbills have already laid eggs at least 3 days ago and hundreds of Black Guillimots are still prospecting all over the island.

Tern eggs are made to blend in with beach materials such as sand, pebbles, and seashells but nesting up and away from the beach can be risky as some tern eggs can stand out against the vegetation and island dirt. Puffin and Razorbill eggs don’t need to be camouflaged as most Alcids nest in deep, dark burrows away from the eyes of arial predators. Puffin eggs are all white and a little smaller than the Razorbill’s bigger, speckled egg.

Last week while over on Green Island, which is ajacent to PMI and only accessible at low tide, we resighted an American Oystercatcher! We know they try to nest there every year, but haven’t yet been able to resight one yet. Now with the numbers on his bands we can find out who he is.

Black Guillemot chick! (about actual size)

Today we started banding Black Guillemot chicks! We have been waiting excitedly to start this, and could hold off no longer!  We had to wait this late in the season because Guillemot chicks take a size 4 band (2 sizes bigger than terns!) and we needed to find chicks that are old enough so the band will not just slip off. In addition to banding the chicks, we also weigh the chicks and take their wing cord length. These measurements will give us an idea as to if and when these chicks are likely to fledge.

Measuring wing cord

In the next couple days we will be checking all the burrows that had eggs in them for chicks. “Grubbing” chicks is almost like a puzzle; we have to figure out where the chick hid, and then how to maneuver our arms so we can reach into the burrow and grab the chick. This can be difficult as some of the burrows are very deep! Our chick banding efforts will let us assess guillmont productivity  this nesting season by comparing hatch and fledging rates to our original egg counts.

Charlie thought they looked cute enough to eat, but swears the chick started it!
