Hello from Metinic!

Sequoia here with this week’s blog. Last Wednesday the 17th we had staff come out to the island to assist us with the GOMSWG census. During this census we identified all nests in the colony. This year we counted 910 tern nests, this is a record for Metinic! This number is also lower than the actual nests present because no matter how hard we try we aren’t perfect at detecting nests. To account for error we use the Lincoln Index which is a form of mark recapture, where we go out and see what percent of the nests were missed. Once this correction was applied we have an estimated 1,021 nests on the island!

We also had some exciting things happen during our census. We found a Leach’s Storm-Petrel, a Savannah Sparrow chick evading a snake who had already caught its sibling, and a few Spotted Sandpiper chicks running around on their stilt-like legs.

Other exciting news, we had our first chick hatch on Friday! An Artic tern chick was the first to be found in our productivity plot. We nicknamed him Eddy due to the fact that Eddy Edwards, the Deputy Refuge Manager, had the closest guess to the number of nests on the island, which we all thought was a bit high but were proven wrong. Friday afternoon and into the weekend we had many chicks hatching, so now we are getting into the grove of weighing, measuring and banding each chick in our productivity plots.

Through all of our adventures we are sometimes lucky enough to be fueled by the homemade snacks that Carol sends out to us, which we greatly appreciate!

Until next time.

Common Terns tend to be the more tenacious nest protectors. This photo was taken while measuring chicks and getting hit by the parents.

This is a good example of Garter Snake predation on Metinic. It’s munching on a unlucky Savannah Sparrow chick. We’ve sent 31 snakes back to the mainland so far this year.

Hello everyone!

This is Emma updating you from Metinic, where we’ve been enjoying the plentiful amounts of sunshine over the past week. With increased temperatures comes layers of zinc sunscreen, great laundry weather, and daring plunges into 50-degree Maine waters after long workdays in the sun.

The birds also seem to be enjoying the good weather. This past week we set up our productivity plots with help from the Refuge staff. Using these plots, we hope to monitor at least 60 total Arctic and common tern nests throughout the season for different factors of reproductive success, including hatching success, survival, and growth of the chicks over time. Although we don’t have chicks yet, we are expecting our first one within the next week!

As the common eider eggs hatch, we continue to see common eider crèches (groups consisting of hens and ducklings) around the island. We have also been monitoring spotted sandpiper and black guillemot nests. The spotted sandpipers nest in low vegetation along the shoreline and in the upland areas. The parents do a great job hiding the nests and it’s easy to miss them if you’re not looking carefully! The black guillemots nest in burrows along the coastline, which makes for fun but challenging work trying to locate them. It really puts our rock-climbing abilities to the test. The overall variation in egg size and coloration among species is really fascinating and beautiful to see.

Can you guess who these nests belong to?

I enjoy seeing the many flowering plants on the island as the season progresses. Just yesterday we came upon a patch of blooming irises! We also don’t mind the wild strawberries that provide a sweet little snack during morning bird walks. We look forward to seeing what the next week brings as we prepare for the annual census that will give us an estimated number of common and Arctic tern nests in the colony this year. It will be interesting to see how the numbers compare to years past.

Happy birding!

Hello from Metinic!

My name is Sequoia, I am one of the two technicians on Metinic Island this summer. I am currently going into my third year at the University of Maine, majoring in wildlife ecology. 

I grew up in a small town in upstate New York, named Moravia. I am an avid outdoors person. I enjoy birding, hunting, hiking, cross country skiing, horseback riding and herping.

While I might not be a “bird person” I wanted to spend this summer learning more about birds so that I can apply the knowledge in the future. Also who wouldn’t want to spend the summer living on such a beautiful island!

My name is Emma and I am the other technician here on Metinic Island. I am a senior at the University of Rhode Island, finishing up my bachelor’s degree in wildlife and conservation biology. Sequoia and I share similar interests, including hiking and working with horses. I enjoy birding along the coast of Rhode Island, especially when there are shorebirds and seaducks involved.

I am thrilled to be spending the summer in such a special place. One of the highlights for me so far was seeing all of the warblers as they passed through during migration. The species diversity on Metinic keeps us on our toes and we never know what we will see next!

We have a bit of catching up to do. We started out the season with a two week quarantine. After flipping a coin, Emma ended up camping in the shed. It wasn’t as bad as it may sound. In fact, one of the best parts about sleeping outside is hearing the storm-petrels at night!

During our first week, we rounded up the 120 resident sheep and moved them away from the tern nesting area. More recently, we kept busy counting the 209 gull nests and 36 common eider nests on the north side of the island. We are continuously documenting all of the amazing bird species here and continue to monitor the common and arctic terns as they get settled and start nesting.

Currently we’ve documented more than 200 tern nests but we’d estimate around 250-300 have been established. Last Sunday we saw the first herring gull chicks hatching and Wednesday we spotted the first ten common eider chicks. 

Though we are already three weeks into the season, we will catch you up as we go. So keep checking in to see what Metinic Island has to offer!

Until next time,

Sequoia & Emma
