Your Observations Matter: The Role of Citizen Science in Spring Migration

March marks the beginning of spring migration, with birds returning to Ontario from their wintering grounds. Scientists and conservationists rely on everyday birders to help track migration patterns, populations, and behaviours. Because of this, citizen science projects empower bird enthusiasts to contribute valuable data while enjoying birdwatching.

Rich understanding and appreciation of our surroundings helps us to develop a sense of place. Today I want to talk about the value of citizen science to help us engage with spaces that are important to us. Citizen science not only provides us with an opportunity to connect more deeply with the spaces that we occupy and frequent, it allows us to feel like we are part of something bigger. Small, grassroot efforts can contribute to conservation management and environmental protection.

What Is Citizen Science?

• Citizen science is when the general public participates in scientific research.
• Birdwatching data is especially useful because it covers a broad geographic range and long-term trends.
• Organizations like Cornell Lab of Ornithology, Bird Studies Canada, and Nature Canada depend on public observations.

Key Citizen Science Projects for Birders in Ontario

1. eBird (by Cornell Lab of Ornithology)

   • A global database where birders log sightings.
   • Helps track migration timing, species abundance, and distribution.
   • Tip: Log your sightings at local hotspots like the Barrie Waterfront, Minesing Wetlands, or Copeland Forest OR in your own backyard. 

2. Project FeederWatch (Birds Canada & Cornell Lab)

   • Runs from November to April, tracking winter bird populations.
   • March data is crucial for understanding how birds transition from winter to migration.
   • Tip: If you’ve been feeding birds all winter, report what you see before the season ends!

3. NestWatch

   • Focuses on bird nesting habits, monitoring when and where birds build nests.
   • Great for homeowners with backyard birdhouses or nesting birds nearby.
   • Tip: Keep an eye on chickadee, bluebird, and tree swallow nests as the weather warms.

4. Global Big Day (May Event, but Plan Now!)

• A worldwide birding event where birders count as many species as possible in a single day.
• Spring migration peaks in May, but March is a great time to scout locations and practice bird identification.

Why Your Observations Matter

• Helps scientists understand climate change’s impact on migration patterns.
• Aids in conservation efforts by identifying declining species.
• Contributes to local and global bird research, ensuring better protection for habitats.

How to Get Started

• Download the eBird app and start logging sightings on your walks.
• Set up a feeder and record birds for Project FeederWatch before April ends.
• Install a nest box and participate in NestWatch by tracking nesting behaviors.
• Join a local birding club or Facebook group, like our group Ontario Birds to share observations.

By identifying and reporting species that we see in spaces that are important to us, not only are we further connecting to places that matter to us, we are helping to conserve them and the species that inhabit them. Every single sighting is of value, whether it's a common chickadee or a rare warbler. By becoming more involved in identifying and reporting species in your area you may find yourself even more appreciative of the local biodiversity. You're also actively helping to protect and understand bird populations. 

I hope you invite the opportunity to grow in your knowledge and appreciation of the species that exist in places we call home.

Warmly,
