First week on the Island and already so much has happened! There are just two of us here on this small 17 acre island off the coast of Jonesport, ME, but it feels a whole lot bigger. We arrived Thursday by boat, where we hauled all our gear into our small 12 x 10 cabin, our home for the next 12 weeks. With limited solar power and no running water, there’s definitely an adjustment period. Every morning we set our alarms for around 6:30. At 7:00, we record the weather, including wind, temperature, visibility and sea conditions. We then make a walk around Eastern Brothers (walking across the bay or rowing our boat, depending on the tide) and conduct a morning bird survey. We’ve already had a high of 184 Black Guillimots and 7 common terns, which is promising for this season. After we’ve finished, we have breakfast which is cooked on a small two burner propane stove (oatmeal and cranberries has been our go-to). Next, we go out to our observation blinds on both Eastern and Western Brothers to watch for tern and alcid activity (alcids are a family of birds which include Atlantic puffins and razorbills). The terns are here daily, letting their presence be known if you get too close to their nests (we’ve already found a nest with 3 eggs and another with 2, hoping the other pair will nest soon!). It’s not unusual to watch as the male brings back fish for the females who are sitting on nests. We have yet to see any alcids, but we’re not discouraged because it’s still early in the season. The weather here has been warm mostly sunny, giving us excellent views of all this island has to offer. Keep up with us and tune in next week and for the next 12 weeks, this is looking to be a great field season off the coast of Maine!

The nesting season is ramping up on Metinic! We found our first tern egg on Wednesday and more nests have popped up every day since.

Elsewhere on the island, we’ve found Common Eider, Herring Gull and Great Black-backed Gull nests. Some of the island’s birds are further along and already have chicks. At least one eider clutch has already hatched, with the three ducklings sticking close behind their mother as she cut through the waves. On our first trip to the southern end of the island, we came across half a dozen Killdeer chicks darting around the marsh while several Canada Goose goslings swam across a protected cove with their parents.

Killdeer chicks can run soon after they hatch. They also look like cotton balls on stilts.

Metinic is unusual among Refuge seabird islands in that it hosts a permanent terrestrial predator: garter snakes. Though generally small, these snakes could pose a threat to diminutive tern chicks, so we do our best to catch any near the colony. When caught, they often release a musky smell that fades from clothing after a few hours. These snakes then take a one way trip to the mainland, where they can get their fill of rodents, away from nesting seabirds.

This snake and two others are now spending their days near Rockland.

Between stretches of fog and steering sheep away from the tern colony, we managed to find some time to continue our shorebird monitoring efforts. People up and down the Atlantic coast are curious about shorebird numbers and movement, so we do our best to keep an eye out for birds on the rocks and beaches. It’s also a good way to get our species list up. Two American Oystercatchers and a Purple Sandpiper helped to get our list up to 81 this week.

Shorebirds can often be found in mixed-species flocks. This Purple Sandpiper was noticeably smaller than the Black-bellied Plovers and Ruddy Turnstones it was with.

Until next time!

This week Petit Manan welcomes the remainder of our crew- Shelby and Jimmy! And with them they brought nesting terns and beautiful weather!

As our second week on Petit Manan comes to a close, we have given up our reign of the island to the birds. No longer can we go to the outhouse in the middle of the night without hearing the territorial “ka-ka-ka” of Common Terns before they swoop towards our heads. Where once we could walk freely there are now hidden nests and incubating mothers that we must be careful not to disturb. And we couldn’t be more excited!

While searching for red-backed salamanders, I found this year’s first Savannah Sparrow’s nest hiding under a rotting log!

And finally the one we’ve all been waiting for… the first tern egg of the season! Since then we have found three more nests, but without the safety in numbers of the whole colony nesting, these terns may have abandoned their egg so not to be targeted by Peregrine Falcons.

We hope to have another Egg-cellent week, as next we begin checking rock crevices and artificial burrows for Atlantic Puffin, Razorbill, and Black Guillemot eggs!

Until next time here is a bit of wisdom, “I value my garden more for being full of blackbirds than of cherries, and very frankly give them fruit for their songs.” -Joseph Addison

The first common tern egg of (hopefully) many.

It seems as though Wednesdays are the most eventful days here on Ship Island. Last Wednesday  was spent scouring the island for Garlic Mustard plants. This Wednesday was a whirlwind of events. Not only did we find our very first tern nest but it also contained our first egg! Along with that our island supervisor Meredith spotted a roseate tern while we were sitting in the blinds.

Aside from this tern excitement we had two seal encounters right on the shores of our island! I found this so exciting because usually when observing the seals we must do so with a spotting scope to see them on the East and West Barges. However during our blind observation on Wednesday we had an adult seal haul out on to our beach and spend a little time sunning itself.

In our area we have two species of seals, western Atlantic harbor seals, and grey seals. The best way to tell them apart is by looking at their heads. Harbor seals have more of a smaller dog nose with not much of a neck and grey seals have larger ‘horse like’ faces and a more pronounced neck. The seals I’ve most often observed were the western Atlantic harbor seals on East Barge. This is also what we had come visit us Wednesday morning.        Later in the day when all the work around the island is complete is when  I enjoy observing our seals– mainly because right now is their peak pupping time (mid May to July), so we seem to have new pups arriving everyday. On this ever so faithful Wednesday evening I got the privilege of observing a very new harbor seal mom with her pup (I could tell he had just been born as some of the birthing organs were still attached).

What surprised me most though was this new mother promptly lead her new pup into the ocean. This is surprising because everything I’ve read about harbor seals says the pups can’t swim till at least an hour after birth, and here this moms bringing her pup in minutes after birth. Almost immediately after entering the water our new mom brought her pup further into the water (toward Ship I.). This was in order to bring her pup further away from the other seals. So I packed up my things and headed back to the cabin assuming the days excitement was over. Upon returning to the cabin I saw that Meredith had left on a photography adventure. A few minutes after that I received a text from stating there was a pup on our shore. Sprinting to meet her, she showed me what she had found: sure enough sitting atop the seaweed was a pup.

Shortly after looking at the pup longer, and seeing a small piece of umbilical cord, I realized this was the seal pup I had been watching only 20 minutes prior. Meredith and I proceeded to sneak away as not to scare off the mother wherever she may be. Most of the time mothers don’t leave their pups because they need to be together for 4-6 weeks so the pup can nurse. Pups can also be vulnerable to some predators. After dinner Meredith and I went along the islands edge to check up on our young visitor. What we found was his mother hauling out of the ocean to retrieve her new baby. We quickly snuck away so we didn’t disturb them, thus ending another successful Wednesday on Ship Island.

Till next week,

Hi all!  Helen here!  My first week with the seabirds on Metinic Island has been full of exploring, birding, and learning new things!  We started out the week by rounding up all of the resident sheep and driving them to the southern end of the island where we put up an electric fence to keep them out of the tern colony for the season.  We did this just in time as both the arctic and common terns have returned and are actively seeking out mates and nesting sites.  We have begun observing the terns from the blinds and have watched them settling in throughout the week.  We have seen the terns landing on the ground, evaluating various potential nesting sites, and showing courtship behaviors such as the males presenting the fish they caught to females.

Common terns checking out the area! 

The terns aren’t the only ones settling in for the season, the black guillemots are courting and seeking out burrows in the rocks as well.  We have also observed a number of common eider nests with eggs!  We even saw one hen with three ducklings today, which is early for them.  We are expecting to find many more eider nests in the coming weeks as they are still displaying courtship behaviors.  To prepare for the arrival of the chicks, we have begun setting up snake plastic as a means of predator control.  Metinic has a population of garter snakes who enjoy feeding on the seabird eggs and hatchlings, so we set out black plastic that the snakes will be attracted to because they create a warm place for them to hide.  We will periodically check the plastic and gather any snakes into a bucket to release them on the mainland.

Along with setting up and preparing for the upcoming season of seabird chick monitoring, we have been keeping track of our other feathered friends on the island.  Every day we start out with our morning point counts then spend the day exploring around and recording any additional bird species seen/heard, and we end the day with shorebird counts right before sunset.  So far, Mark and I have recorded 71 different species!  Metinic is a great location to support a variety of birds as the island includes rocky coast, open field, forest, wetland, shrub, and pond habitats.  We are looking forward to adding to our list as the season progresses!

Happy spring migration from the Ship Island crew of two! As the common terns begin to establish the breeding colony and initiate courtship, we’ve been busy making sure the island is ready for them; in short, this means lots of invasive vegetation control. Typical plant culprits include black bindweed (Polygonum convolvulus) invading the brand new gravel nesting areas and garlic mustard (Alliaria petiolata), which we struck hard with the help of some mainland visitors.

Garlic mustard flowering stems can be plucked by hand, but the young florettes left behind need to be blasted with vinegar.

After our push against the invaders, we’ve been able to turn our focus to observing the wildlife around us, which includes numerous passage migrant birds on their way home from the tropics, in addition to resident breeding birds and neighboring seals. These early weeks will be filled with anticipation as we wait for the terns to start nesting, but in the meantime there is plenty to see and do. So far, we’ve documented 40 different species to visit Ship, plus a bonus hybrid Mallard x American Black-duck!

Many passage migrants are only here for a single day before they take off again to continue their nocturnal migration. Here, a chestnut-sided warbler (Setophaga pensylvanica) gleans a precious insect meal to refuel.

Since we don’t have too much in the way of tern nesting progress to report, we thought we would provide a quick introduction to this year’s Ship Island dream team. First off is our lovely Island Technician:

Greetings from Ship Island!!! My name is Kelby Leary ( Yes that’s me in the photo above) . I was born in raised in central Maine and I’ve always loved being outdoors. I just finished my first year in the wildlife ecology program at The University of Maine and working of Ship Island is my very first field position. This is also the most time I’ve spent on the ocean as the area I am from is pretty heavily forested. I’m excited to learn more about all the animals that frequent the island as well as gain valuable field skills. In this first week prepping for the colony we haven’t been to insanely busy so we’ve had some time to really get to know the island. So far my favorite things to do in my free time on the island are watch the seals on the neighboring barges (I’d also never seen a seal in real life before moving to the island) and sitting on the beach watching the sandpipers.

And your friendly neighborhood Island Supervisor:

Hi everyone! I’m Meredith Miles, and I’ve been spending my time since graduating from Bates College last year hopping from field job to field job around the world. My work has recently taken me to Alaska, Peru, and Oklahoma, but I couldn’t be more psyched to be returning to beautiful Maine for the summer. This season I am most excited about getting an insider view of seabird breeding season behavior and gaining a deeper understanding of the ecology of this amazing bird group.

We’ll update soon with more news from our tiny paradise. Happy spring!

Meredith and Kelby, Ship I.

Hey folks! Jill and Morgan here! It’s been a surprisingly beautiful first week on Petit Manan Island; let’s hope it’s a sign for the whole season! The island has been lively thus far with approximately 200 prospecting Common and Arctic Terns, but we’re expecting many more to come! Although PMI isn’t the largest of islands, it still receives a good deal of visitors, especially early in the season when birds are migrating North – we’ve seen 61 species thus far! Not all our guests have been of the bird variety though; we also stumbled upon a juvenile Grey Seal on our rocky shores earlier in the week!

Downy Woodpecker sighting!

The start of the season means preparing the island for all the work to be done in the months ahead. This means setting up observation blinds, for band resighting and future monitoring of foraging habits and chick health, as well as collecting marine debris, building burrows for Black Guillemots and Atlantic Puffins, and marking potential Leach’s Storm-petrel burrows. Daily Alcid counts from the top of the Petit Manan Light have also begun. On a windy day it can get rather cold up there, especially for Jill, who hasn’t quite gotten used to the Downeast summer having just returned from a seabird job in the Galapagos!

IMG_3183.JPG

Can you spot the Leach’s Storm Petrel burrow? We’ve been searching the island for these small holes in the ground this past we week, and we have found 170 potential burrows!

As we prepare ourselves for the research season ahead, the birds are doing the same. The puffins and guillemots are seeking out rock crevices and other sufficient and creative hiding spots for their burrows. The male terns are attracting their mates with a Sandlance dowry. The Common Eiders are seeking out areas of high vegetation to form their nests. And the Peregrine Falcons, Merlins, and gulls lurk about hoping to catch a bite to eat with all these new dining options in town.

The Atlantic Puffins have already begun choosing burrows!

Till next time, here’s a joke to hold you over – Why did the Puffin have a stomach ache? Because it had Alcid Reflux!

Best,

Morgan & Jill
