Bird Banding! guest post by Meghan Jacklin

Ever wonder what it’s like to be a biologist? It is a truly rewarding career, but it might not be what you expect! Read on to learn about what a career in biology can be like, in a post from our guest writer Meghan Jacklin.

My name is Meghan, and I am a biologist in Edmonton Alberta. I was first inspired to care about wildlife and natural areas from a young age through my love of wolves, and my family canoeing and camping activities. I struggled to find the right education, until I heard about the Environmental sciences program at the U of A. I got my bachelors degree in Conservation Biology, and then it was time to head out into the real world!

During my degree I started volunteering for a local organization called the Beaverhill Bird Observatory. That is where things got really interesting. The Beaverhill bird observatory studies bird migration through bird banding. But what is bird banding?

Bird banding means putting a lightweight metal band with a unique number on a bird's leg. If this bird is ever caught or found dead somewhere else in the world, we have learned valuable information about that bird and where it traveled!

 Neat! But why do this?

About 40% of the worlds 10,000 bird species are migratory, meaning they spend part of the year in one place and then undertake a large movement to another location for a different part of the year. This can make them uniquely vulnerable – if their habitat, the place that they live, is destroyed or damaged in one area, but not in the other, we may not recognize what the problem is without understanding where birds are migrating to and from.

What else do we learn from bird banding?
We also can determine whether a bird hatched this year or is an adult. This helps us understand whether problems are occurring at the breeding grounds (if not many babies are hatching) or if problems are at the wintering grounds (there are enough babies but not many returning adults). We can check roughly how fat a bird is! This is important because some birds migrate hundreds to thousands of kilometres, sometimes without stopping. They must put on lots of weight before starting so they have enough fuel to make it to their journey's end.

How does it actually work?
We first have to get up reeeaaally early, because that is when the birds are around! We get up half an hour before the sun even rises – urg. It is worth it though! We then set up a series of very fine mesh nets, so fine that you can hardly see them. As the birds are flying through the bushes in the early morning, they don’t see the nets, and fly right in.

Then the staff and volunteers get busy. We check the nets every 30 minutes and remove every caught bird, and place them in individual cloth baggies to bring back to our banding lab. It takes lots of training, and dexterity to carefully take the birds out of the nets! We also get our exercise in, seeing as the distance to check all the nets is around 1 km in length, and we need to walk that every 30 minutes.

Once we get back to the lab, we start the banding process. We add the band using special pliers, and this part is actually pretty easy to learn. What’s harder is accurately determining the age and sex of the bird. That requires study and practise, and careful reading of the “bird banding bible” Pyle, the widely accepted expert in North America.

During the banding process, we also get pooped on… a lot! We learn a lot about birds and can help their species to thrive, but no wild bird enjoys being caught, and they let us know! We are covered in poop, and little scratches from beaks and claws by the end of a day. Most songbirds don’t hurt too much when they bite, but if we catch a bird used to cracking seeds – ouch!

 With all that said, bird banding is a very rewarding path for a biologist. Until you start to look and listen, you don’t realize the beautiful colours, shapes, and sizes of the birds right here in our backyards. With all the troubles that birds face, from window strikes, cat predation, habitat loss, and changing climate, it is wonderful to know I am making a difference.
If this sounds right for you, it’s never too early to get started. Many banding stations are open for the public to visit, volunteer, and learn about this important work. Look for one near you!
