The newest space robins
At 6:40 am five American robins flew into our nets. What a great start to the day!
Other bird species we’ve seen so far
While we’re on the lookout for American robins, we see lots of other bird species. Brian’s been taking some pretty spectacular photos of them, so we thought we’d share them with you.
Busy as a beaver!
The other evening we decided to go check out one of the many nearby beaver lodge and dam complexes. We are in Canada after all!
Have you ever heard the expression “He/She is as busy as a beaver”? It comes from the fact that beavers are famous for keeping themselves very busy gnawing away at the trunks of trees until they fall to the ground – timber! – and can be used to build their homes (lodges) and dams to create lakes where there were previously small streams. You can learn all about beavers here and the structures they build here:
Although I had heard a lot about how busy beavers are, I had never seen it with my own eyes and wow, was I impressed! Seeing first hand all the work these beavers have done made me feel awfully lazy. Take a look for yourself:
That’s all we have for today, but tune in again soon to meet the next batch of space robins!
This morning we woke up to a lot more bird songs in the forest compared to what we’d been hearing in the days before. We were pretty excited. We waited and watched for any of them to fly into our nets.
In this video, you can’t really see that there are lots of birds around, but you sure can hear them! At the end of the movie, you’ll also see Brian and Nicole coming out of the woods where we have some nets up. See those cloth bags they are carrying? Each one has a robin in it! The bags are used to transport the birds safely to the location where we work with them. Our nets caught five birds this morning, all at once. We really hit the jackpot!
Meet our four new space robins: Zee, Big Mac, Pepperoni and Billie Jo
We’ve got four more space robins to introduce you to today! You may be wondering why there are only four birds to introduce you to today, even though we actually caught five.
It’s because not all of the birds we caught were big enough to carry the mini-GPS tags, so we had to let them go after weighing them. Here are photos of the four new space robins:
Suiting up a space robin
This movie shows Nicole and Brian suiting up one of our new space robins with a harness and mini-GPS. You can see the bird is relatively calm and cooperative.

Releasing a space robin back into the wild
This movie shows Brian releasing one of our space robins back into the wild. Nicole showed us that if you put a bird on it’s back, it stays very still because it has no experience being on its back in the wild – it just doesn’t know what to do on it’s back, so it does nothing. The movie shows Brian giving this technique a shot – pretty neat!

How to hold a little bird
This last movie is of Nicole showing us how to hold a little bird. She does the demonstration with a cute little Black-capped Chickadee, not a robin. You can read about Black-capped Chickadees here: https://www.allaboutbirds.org/guide/Black-capped_Chickadee/id. Nicole shows us two different ‘grips’ (or holds) that keep the bird safe while it is being examined: ‘Bander’s grip’ or ‘Photographer’s grip’.

More space robins are on their way!
Well, that’s all we have to report today, but we think that a whole lot more robins will be showing up in Slave Lake very soon. That’s because Nicole has a friend living in the city of Edmonton (which is located about 250 km south of Slave Lake) who told her yesterday that there are tons of robins in Edmonton all of sudden. As the birds make their way north from Edmonton, some of them will likely stop in Slave Lake to eat and rest. So stay tuned!
Our adventure began in Vancouver, British Columbia, Canada on Wednesday, April 13th. After a solid day of driving up and over the Rocky Mountains, we arrived in Alberta on Thursday. Here are some photos from the drive. You can see our team mascot in the photos – a stuffed animal version of an American robin. His name is Chirpy, and we brought him along because Mrs. Christie-Blick’s 5th grade class at Cottage Lane Elementary asked us to. You can see that the kids even outfitted Chirpy with a pretend GPS unit and string harness.
Check out our field site & meet our team!
On Thursday evening around 8:30 pm, we arrived at our field site in the boreal forest, where we will catch and tag 30 American robins over the next week to ten days. We are working and collaborating with scientists at the Lesser Slave Lake Bird Observatory (LSLBO) and the Boreal Centre for Bird Conservation, which are located just north of the town of Slave Lake, Alberta.
And, here’s a photo of our team. My Dad and I are on the far left. Willem is my super-handy Dad who has come along for the adventure and to help us with whatever we need help with – thanks Dad! Next to me are Ruthie and Brian, who are both graduate students at Columbia University in New York. Ruthie is working towards her PhD in Earth and Environmental Sciences at the Lamont-Doherty Earth Observatory, and Brian is working towards his PhD in Ecology, Evolution and Environmental Biology. Nicole – our resident bird banding expert – is on the far right. Nicole is a bird biologist who has been working at the LSLBO for almost ten years. She knows a whole lot about the birds here, and how best to catch them!
Check out our team T-shirts! Nicole drew this ‘space robin’ and we all liked him so much that we got some fun t-shirts made with him on it. If you looked through the set of slides I posted on the first blog post, you might be able to guess why Nicole drew the robin wearing a NASA astronaut’s space suit. Any guesses?
If you haven’t already figured it out, the robin is wearing a space suit because we are using information collected from satellites in outer space that are looking down at the Earth with special sets of ‘eyes‘ that we call sensors. From these satellite sensors, we will learn about two main things:
First, some of the satellites – the GPS satellites – tell us exactly where the robins are as they are migrating. We’ll call these the ‘bird location satellites’. You can learn more about them here.
Second, other satellites tell us about the habitats the robins are using or avoiding as they migrate – like, if there is still snow on the ground, or if they are spending time in a forest or a grassland, if the plants around them are very dry or sitting in big puddles of water, or if there is a forest fire burning. We’ll call these the ‘bird habitat satellites’. You can learn more about them here.
In addition, a third set of satellites will actually be used to transfer the information on where the birds are, from the bird, to me and my team once we’re back in New York. We’ll call these the ‘information transfer satellites’. You can learn more about them here.
Who knew that robins and satellites could work so well together?!
How to catch a robin
The first thing we did after getting a good night’s sleep was to make a plan for how to catch 30 American robins. I’d assumed that we’d be using the ‘playback technique’ where you play recordings of singing robins on one side of a mist net in the hopes that a curious bird hanging out on the other side of the net will fly into as she or he flies over to check out whose singing in their territory. I was familiar with this technique from my work on another project in Alaska, but Nicole had another idea that she thinks will work better to catch the robins migrating through our field site.
Nicole told us that the birds will be attracted to a bird bath because migrating robins are both thirsty and like to keep clean by bathing, but there’s not a lot of water available to the birds at this time of year because the nearby lake is still frozen and it hasn’t rained enough to create many puddles. So we filled up a big plastic box with water (this is the bird bath), and put it in a nearby field. Then, we got an empty soda bottle, cut a little tiny hole in the bottom, and stuffed a small piece of blue sponge in it. Next we filled up the soda bottle with water and hung it upside down over the bath, so that drops of water would fall from the sponge – kind of like a shower. When the drops of water from the bottle hit the bath water, they make a ‘drip drip drip’ sound that Nicole thinks will attract thirsty robins! We also put up four mist nets in a box shape around the bird bath so that any potential bathers would fly into a net on their way to/from the bath. Genius! Here is a photo of the bird bath and net setup.
While we waited for robins to notice the bird bath and hopefully get stuck in our nets, we went inside to get ready for the first bird that we hoped to catch. Ruthie and I worked on testing the mini-GPS tags (made by Lotek wireless), making sure they were fully charged, and programming them to work once they’re attached to a bird. Brian and Nicole worked on making the harnesses that the mini-GPS tags will be attached to, and my Dad went on a hunt for more harness material.
Not much time went by before our first American robin flew into a net, although it wasn’t one of the bird bath nets, it was a net that the LSLBO’s Bander in Charge (Richard Krikun) had set up about 2 km away for his own study. Thanks for sharing Richard!
Meet our first space robin: Trail Blazer
Meet ‘Trail Blazer’ – our first volunteer space robin! Isn’t he cute?
Here is a video and a picture that show how Trail Blazer was caught, how he was weighed, and then equipped with a harness and mini-GPS tag.
Once we were sure the harness and tag were secure and not bothering him, we took Trail Blazer outside and released him. He seemed to fly just fine with his new gear on, and perched for a while in a tree to do some feather rearranging. We hung out near him for about an hour to make sure that he was okay. Eventually he flew off confidently, presumably continuing his migration northwards.
Safe travels Trail Blazer!
Where is Trail Blazer migrating to and where will he start his family?
We won’t know the answer to these questions for another two months from now because the mini-GPS tag that Trail Blazer is wearing will only send information on where he’s been to the ‘information transfer satellites’ once, in mid-June. Not only did we program his mini-GPS tag to collect information on where he decides to start his family, but also to collect information on the migration route he’ll take to get there! We programmed Trail Blazer’s tag to record his location every two days from the day we caught him (today) until about June 15 when his mini-GPS tag will likely run out of battery power. It’s a long time to be patient and wait to find out where he goes. While we’re waiting, we’ve got 29 more American robins to catch and outfit with tags, so we’ll have plenty to do to keep us distracted for a little while.
Check back here in a few days for more pictures, videos and space robin introductions!
This field blog is written for a very special group of people – elementary school children who are curious and eager to learn about Earth and the animals we humans share it with! While I’m getting ready to head to the field, I wanted to give kids like you some background information that should help you understand the upcoming series of blog posts I’ll send from northern Alberta, Canada. I asked my colleague Mary McLean-Hely, who is a friend and expert curriculum developer, to write the article below for elementary school kids just like you – I hope the information is both interesting, and even a little fun! –Natalie Boelman, ABoVE researcher with Lamont-Doherty Earth Observatory and Columbia University
Have you ever left on a trip during a school break only to get stuck on the highway with what seems like millions of other people? Well imagine hitting the road with three billion people! That’s about half of the people on Earth!
That’s also how many birds travel, or migrate, each spring from all over North American to the arctic and boreal regions in Canada and Alaska. Some populations of American Robins are among these three billion birds.
Why do the American Robins travel north in the spring? The tundra and boreal (or northern) forests near the poles are cooler and provide great conditions for robins to mate and raise families. It’s like an all-you-can-eat buffet of plant life and insects! There are countless mosquitoes that fill the air in big, gray, buzzing, bug clouds. Robins feast on them! They also like spiders, beetles, seeds and berries, which are plentiful. Yum!
In addition, the summer days are very long and provide the busy birds time to find a mate, make a nest, and take care of their eggs and baby robins. There are not a lot of predators, or animals who feed on robins, providing a safe place to raise their chicks.
Although the individual days are long, the breeding season is short. During the short time, birds have to feed their chicks as much as they can with protein-rich insects and spiders. They also have to fatten themselves up as they will need the energy to fly south.
The start of cold winter temperatures tells the birds to start their fall migration. The birds and their young hit the road again flying south to warmer regions, like New York or California, for the winter. It’s kind of like millions of people heading home at the end of summer vacation. We’ll be learning and telling you more about their birdie vacation as it happens, so stay tuned.
Climate Change and a Migration Mystery
Recently, the climate in the polar regions has changed. Scientists think it may affect the migration pattern and habits of the American Robin but they aren’t sure how. It’s a migration mystery!
There are many scientists all over the world studying the changes in the climate in the polar regions. With the information they gather, they learn about how climate change affects plants and animals living near the polar regions.
Together with other scientists, I’m studying the environment, growth of plant and bug life, and other animals in the bird’s habitat. With this information, we will learn how the changing climate affects the birds and other animals, as well as plant life. We’ll be able to make predictions about what may happen in the future for the migrating birds.
Come Fly with Me!
My team and I are currently en route to visit the boreal forest near the Town of Slave Lake in Alberta, Canada, and they will be taking a new piece of technology. We have tiny Global Positioning System (GPS) devices that we will put on the birds. The GPS device is a radio system that uses signals from satellites to tell you where you are and to give you directions to other places. It works like the navigation in your car or on the maps on a smart phone. It sends a signal about where the bird is the same way a phone sends a signal about where you are. Then, it shows where the bird is on a bird map app.
But how do you catch a little robin without hurting it? Sing it a song! We will attract the birds by playing bird songs. When the birds come, we will catch them in large, soft nets. Next, we will carefully and gently place the GPS devices on the birds. Finally, we’ll set the birds free. The robins will probably be a little scared but they’ll quickly recover and continue on their way. If all goes well, the GPS devices will send data about where the birds are. Our team will use this data to see the routes the birds take as they continue their migration. In this way, these tiny birds will help scientists like us understand big changes facing the world.
Over the next ten days, I will bring you along on this adventure to Alberta so you can see how we’ll be working to solve the Migration Mystery of the American Robin! I hope you’ll check in every couple of days to see what we’re up to. I’ll do my best to post pictures and short videos so you can see things in action, and meet the members of my field team and the birds we catch. In fact, a group of smart and curious 4th and 5th graders at Cottage Lane Elementary in Blauvelt, New York (where my daughter goes to school) has chosen some great names for the birds, so I’ll introduce you to each of them as we catch and attach GPS tags to them.
To get yourself in good shape for understanding my series of blog posts from Alberta, I suggest you spend a few minutes going through this set of slides I’ve prepared for you! I hope you will find them fun and interesting: http://above.nasa.gov/Documents/blog/CLE_migrationmystery_Boelman.pptx
