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.

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 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

Hello hello all amazing and wonderful seabird fans!

Hallie here, writing from the currently gloomy and rainy but still wonderful Petit Manan Island!

It has been a very exciting week here on the island! We completed our GOMSWG census as Brandon highlighted, and we had a total of over 1400 tern nests, 640 Laughing Gull nests, and 47 eider nests! In addition, we already have over 47 Puffin nests, 54 Black Guillemot nests, 20 Leach’s Storm Petrel nests, and even a handful of Razorbill nests!

But if you are wondering the specific reason why I cannot wipe a smile off of my face — it is because our chicks have begun hatching! After a period of incubation specific to every species, the chick will begin the long and tiring journey of hatching.  Chicks have a specialized calcified bump on the ends of their bills called an egg tooth, of which they use to slowly chip away at the eggshell from the inside, making their way around until they hatch. For most individuals, hatching takes around 12-48 hours, and they emerge looking like cute little fuzz-balls with little flipper feet — and trust me, its adorable.

4 day old Savannah Sparrow chicks!

From the point of hatching on, for all chicks on the island including the cute little Savannah Sparrow chicks pictured, the job for the parents arguably becomes harder. The chicks not only still require periods of incubation, but they also need to be fed multiple times a day, sometimes even multiple times an hour! We have been finding some chicks increasing in weight by over 300% in a 24 hour period! They honestly grow up so quickly.

For the next few weeks here on PMI, we will be monitoring the productivity and development of our tern chicks, doing provisioning where we will identify fish that the parents are feeding their chicks, collecting fecal samples to look at what the adult birds are feeding themselves, and banding chicks with 2 bands that we can use to re-identify them in later years. Today, if we are lucky, we may even band our first puffling — something that I have honestly dreamed of doing ever since I banded my first bird 4 years ago!

Until next time, bird nerd friends!

(A few of our first of hopefully many eggs on Ship!)

Hi folks!

Bobby from Ship Island here, as the cleverly constructed title suggests, we have eggs here on the island! A total of 13 eggs in 12 nests, which gives us hope that the birds are willing to nest for the breeding season on the island. Whenever Colin or I find a nest with an egg, we turn the egg to stand up, that way when we check the egg later on we can tell if it has been incubated (the egg falls back on its side from the tern sitting on it) or if it has not (egg is still standing up).  However, the number of terns that have been showing up since the last blog post has not been ideal. We have not seen more than 50 terns at once on the island for the past week and a half, at this time last year for contrast, there were 519 breeding pairs. It has become crunch time as we are using our final method to attract the terns back, creating our own tern colony.

This is done with two simple props, audio of a tern colony through multiple speakers, and using wooden decoys of terns (bird manikins essentially). These both simulate that a real colony is on the island and that it is safe to nest for the breeding season. Although it reminds me of The Truman Show in some ways, this method is the best bet to have the terns stay and nest immediately to allow them to be raising young in time for their migrations later in the summer. To paraphrase Princess Leia from Star Wars, the tern decoys may be our “only hope left”, but Colin and I are waiting confidently for our feathered friends to return. Don’t stop believin’ in Ship Island!

Hello from Petit Manan Island, once again!

The breeding season here on the island has really taken flight since our last post, with the majority of the tern colony having laid eggs, as well as the Puffins, Guillemots, and even some Razorbills! I guess one could say that it is off to an egg-cellent start!

We have been focusing the majority of our efforts every morning on re-sighting birds that have been previously caught and banded either by biologists here at MCINWR, or at other colonies along the Atlantic coastline. We even are lucky enough to occasionally spot birds that were banded along their wintering grounds in Brazil and Argentina. But why is it that re-spotting these birds is so important?

One of the terns we work with, the Arctic Tern (Sterna paradisaea), is quite the world traveler. Once they finish breeding in Maine or along other locations across the arctic, they leave to embark on one of the longest migrations in the bird world, eventually ending up in Antarctica! One bird, tagged and tracked from the United Kingdom, was recorded to have migrated 59,650 miles in one year, making it the longest migration that has ever been recorded. Let me put this straight – this is the equivalent to the bird flying around the world twice, and then adding on another 10,000+ miles. Considering these terns live to upwards of 30 years, this bird will travel farther in its lifetime than most people.

And this is why re-sighting birds is so incredibly important! It not only gives us information like how old the bird is or potentially where it was born, but we can also piece together the puzzle of exactly where each bird travels to during these super long and intense migrations, and more importantly gives conservationists a better idea of which land to protect in order to assure that these birds are around for years to come. Definitely makes waking up at 5 am every morning only to sit in a tiny box for 3 hours a little bit better!

Pictured left to right: A sleepy Common Tern that we identified as an individual banded in Nova Scotia in 2013; Puffin nap time makes re-sighting bands a difficult but adorable job; an Arctic Tern with 2 bands that we identified as an individual born here at PMI in 2016

Happy band re-sighting!

So far around the island we’ve come across Common Eider, Mallard, Savannah Sparrow, and Spotted Sandpiper chicks. Although a little behind schedule, we were beyond happy to finally find our first Common Tern chicks! Soon we will start banding them and taking measurements. Hopefully we will start seeing more every day!

Our first Common Tern chick!

Our terns have been acting different than normal. Rather than settling down to incubate, many of them appear to be much more active flying around and leaving the island. We grew suspicious that there might be an owl around. In order to make sure it doesn’t disturb our terns, we set up a total of 17 foothold traps covering all sections of the island. When we placed the traps, we put them in areas that seemed suitable for an owl to land. If the owl lands on the platform that contains the trap, its leg will be caught. This trap doesn’t hurt the owl because it’s padded, but it allows us to capture it so it can be relocated. Though our minds were focused on an owl, we didn’t forget about our frequent Peregrine Falcon visitors. To prevent any unintended capture, we made sure to set off the traps during the day.

Only a few days after setting the traps, we caught the owl! Morgan and I noticed the terns were once again acting strange during our night stint, where we took shifts watching the colony between 6:00 PM and 12:00 AM. The next morning the terns were dive-bombing at the ground, and I could see through my binoculars that the trap wasn’t on the post anymore. It seemed unlikely that we caught an owl, especially since we weren’t completely sure we even had one, and last year it took over 2 weeks to catch it! We walked over expecting to find something like a gull caught up in our trap, but to our surprise it was a Great Horned Owl! We safely caught the owl, covering its head so it would stay calm, and removed him from the trap. It already had a band on its leg, so we suspect that it might be the same one from last year. The owl will be brought to a rehabilitation center to make sure it isn’t hurt, and it will be released somewhere far from our terns! We are so thankful we caught it in time, especially now that our eggs are hatching!

Outside of bird research, we enjoy watching the Harbor Seals bask in the sun and swim around with their pups. The seals can be found on two adjacent islands. One pup decided to visit us on Ship this week. We were nervous when we didn’t see the mom around, but we were taught that after 3 weeks the pups begin to live on their own.

Ship has been very busy this week. We’re hoping to continue to wake up to new surprises every day, but only good ones!
