Posts Tagged ‘Maine Coastal Islands National Wildlife Refuge’

Hello from Petit Manan Island, this is Hallie again!

I just wanted to write a blog post to give a shout out to the Friends of Maine Coastal Islands! I was lucky enough to get to talk to most of you briefly the other day while you were enjoying the island from the Acadia Explorer — but I did not get the chance to give you all a massive THANK YOU for everything that you do for the refuge. Work like this would not happen if it weren’t for your support. The work that we are doing out here is so incredibly valuable — the seabirds are benefiting tremendously, as well as all of the young scientists who get to learn from the refuge biologists and the abundant wildlife on these islands. Personally, this is an experience that I will be remembering for the rest of my life, and an experience that is helping me take the next steps towards being the scientist and conservationist that I aspire to be one day!

Thank you all so much again for taking the time to sail out here to PMI and give us a warm hello, as well as for all of the endless support! (And especially to Carol for all of the vegan treats she sends our way each week!)

With Many Thanks,

PMI

Hello friends, Hallie here from Petit Manan Island!

Life here on Petit Manan is going so well. Our tern chicks are hatched and getting close to fledging, our pufflings are fluffier and plumper than ever, and we even have our first black guillemot and razorbill chicks.

One of the cool things about working on such a small island like this is when you have a new avian visitor, you notice. We are up to 110 bird species recorded on Petit Manan Island this season, which is remarkable in itself. We have had everything from warblers to short-billed dowitchers to even a least bittern, a small bird that you typically find in marshlands on the mainland. And as well, we have had a lot of birds with interesting plumage show up to the island — like this Common Murre.

Common Murres are usually a dark chocolate brown, which is produced by melanin. This bird,  however, is silvery-grey — a result of a genetic mutation that inhibits melanin production. This result is called leucism, which is similar, yet very different to albinism. Regardless, it makes up for a stunning result — this bird very well may be one of the more beautiful I have ever seen. Whether or not male or female common murres also think so is up for debate — hopefully this bird’s unique plumage will not inhibit it from procreating in the future.

Melanin is one of many ways birds color themselves. The laughing gulls here use melanin to create that dark mask during the breeding season, which they use to deter other laughing gulls from their nests. You also often see birds with darkened wing-tips, like the terns, in which the melanin is used to strengthen the feathers and make them more durable.

But what other colors do we see here on PMI that have significance in birds?  Since we have been catching puffins this last week, I have been captivated by the bright orange feet and bills that the puffins display during the breeding season.  Puffins, and many other birds, get this rich orange-red color from carotenoids — a color they metabolize directly from their food. Puffins use the intensity of this color to show potential mates and rivals how fit they may be. The brighter their bills and feet, the better at fishing and raising a chick they may be! You can also see melanin in the feet and the mouths of black guillemots!

Next time you see a color in a bird, its worth asking exactly why it is that way. Often even the most subtle of colors on a bird have such an immense meaning. I will be doing the same — sitting here wondering why we get tern chicks in two different colors. Any ideas?

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.

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!

Come meet the 2019 Petit Manan Crew!

Hello all! My name is Hallie Daly, and I am one of the lucky bird-nerds that gets to call PMI their home for the summer. I have been working with wildlife for about 9 years now, having started my obsession when I was just 13 years old. I graduated from the University of California, Davis in 2017 with my degree in wildlife, fish, and conservation biology. I have been lucky enough to have worked internationally on a variety of conservation projects in Romania, the United Kingdom, Guyana, the United States, and most recently American Samoa, with everything from plants, large carnivores, squirrels, bats, and birds. Coming to work with the USFWS at PMI is such an exciting opportunity for me, as I have never worked with a breeding colony of seabirds before! Aside from enjoying wildlife, you can often find me backpacking the John Muir Trail in California, reading books about paleontology, painting, and making horrible puns! I have so much to learn and am so excited to apply my knowledge and skills from my past experiences towards the conservation of these beautiful birds.

Hi everyone! My name is Jimmy Welch and I am the supervisor here on PMI for the summer. I am a returning intern and was first a research technician in the summer of 2016 here on PMI. I have since worked with prairie dogs in New Mexico, sea turtles in North Carolina and researched scavengers and small mammals in Maine. I’ve also recently graduated from the University of New England in May 2019 with a degree in Animal Behavior and Environmental Science. I decided I wanted to come back to work for MCINWR and I was lucky enough to be able to return to my favorite island, PMI! I am really excited for the field season and the opportunity to work with such amazing seabird species again. I hope to utilize my previous experience on the island and my diverse field work background to make it a great summer for the PMI crew and all of the wonderful birds here on PMI.

Hey everyone, my name is Devon Jobe and I’m one of the newest researchers working with the USFWS here on Petit Manan Island! I am a rising second-year student at the University of Maine, and am majoring in both Wildlife Ecology as well as Forestry. That being said, this is only my first real position in my field of study and is a totally new and awesome experience for me! I feel so lucky to have been given the opportunity to be part of  such an exciting project working with breeding seabirds, and I can say with confidence that it is shaping up to be the most interesting introduction into the field of Wildlife Ecology I could have hoped for! I still have a lot to learn but I’m looking forward to doing it here on PMI.

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!

Best,

Hallie

Hi everyone!

This is Mary reporting from Metinic Island. I am happy to announce that we had our first eggs on Sunday! We have been monitoring closely to see whether it is Common or Arctic terns sitting on each of the eggs. It is nearly impossible to tell the different eggs apart by appearance alone, so we have to watch closely to see who sits on the scrape. It is very exciting to think that soon there will be little chicks replacing the eggs!

The weather here on Metinic can get a little nasty sometimes. We got rain all afternoon and through the evening yesterday. The wind can really pick up here too, one day last week the average wind speed was 31 mph! Due to the sensitivity of the terns, it is important that we pay close attention to the weather. Disturbing the colony when the weather is bad, especially when there are chicks, can cause the terns to waste unnecessary energy. On days like this, we limit the number of times we enter the colony and in severe cases we do not enter at all.

Check back in with us soon! Hopefully there will be more eggs and some nice weather here on Metinic!
