Did you know snapping mountain-top photos of smog and listening for frog calls can help scientists? Get ideas for how you can participate in citizen science—projects in which volunteers and scientists work together to answer real-world questions and gather data.

Bird Census

Join the Audubon Society's Christmas Bird Count and contribute to a wildlife census that will help scientists assess the health of bird populations.

Red-tailed hawks hunt from a carefully chosen perch, usually a tree branch, fence post, or telephone pole located along the edge of an open field. They dive with their legs stretched behind them and their wings open.
Celebrate Urban Birds

Observe birds in an urban neighborhood for the Celebrate Urban Birds project, and send the data to scientists at the Cornell Laboratory of Ornithology.

Monitor Bird Nests

Join NestWatch, a continent-wide project to monitor bird nests. The project was started by the Cornell Laboratory of Ornithology and the Smithsonian Migratory Bird Center.

The Horseshoe Count

Join The Horseshoe Count, a survey that gets volunteers to count horseshoe crabs during spawning season at beaches in Delaware and New Jersey.

Butterfly Census

Contribute to a census of the butterflies of North America—in the United States, Canada, and parts of Mexico. Participate in a one-day butterfly count in your area for the North American Butterfly Association.

Monitor Water

Use a test kit to sample local bodies of water for water quality data and share the results with other communities around the world.

Count Birds

Participate in the Great Backyard Bird Count, an annual event that gets bird watchers to count birds across the continent and then tallies the highest number of birds of each species seen together at one time.

Observe Appalachian Flowers

Monitor the timing of plant flowering in the Appalachian Mountains as you hike trails. The Appalachian Mountain Club will use the data as part of a study to understand how changes in climate are affecting mountain flora.

Survey Monarch Populations

Help the Monarch Larva Monitoring Project collect long-term data on larval monarch populations and milkweed. Volunteer to conduct surveys in your local area.

Learn About Local Plants

Join the National Phenology Network's plant monitoring program. Learn about plant species in your area and record your observations about observable phases in the annual life cycle of plants.

Observe Plant Life Cycles

Join Project BudBurst to gather environmental and climate change information in your local area. Observe the life cycles of trees, shrubs, flowers, and grasses to see when they have their first leafing, first flower, and first fruit ripening.

Measure Snow Depth

The Community Snow Observations (CSO) project relies on snow depth measurements collected by participants to help scientists understand the impacts of climate change in the mountains. Citizen scientists can submit snow measurements, allowing scientists to analyze the data and integrate it into models and remote sensing products.

Collect Weather Data

Volunteer to join the Community Collaborative Rain, Hail, and Snow Network. The data you help collect will be used for weather forecasting and monitoring, severe weather alerts, and climate studies.

Classify Galaxies

Do what a computer can't! Join the Galaxy Zoo project to help scientists classify galaxies according to their shapes.

Bird Feeder Stakeout

Help Project FeederWatch with a winter-long survey of birds that visit feeders at backyards, nature centers, community areas, and other locations in North America.

Bird Watch

Join eBird, an online checklist project created by the Cornell Laboratory of Ornithology and the National Audubon Society. Ebird allows people to report real-time bird sightings and observations.

Observe Coral Bleaching

If you live in Hawaii, join Eyes of the Reef Network to help monitor and report on coral bleaching and disease and marine invasive species.

Chesapeake Bay Foundation

Love the water and being outside? Get in touch with your state’s local water resource office to find out how your class can volunteer for various projects like tree-planting or oyster-growing. Even if your class cannot do something hands-on, they can promise to take action signing the Chesapeake Bay Clean Water Blueprint pledge, or something similar for your area.

Observe Wildlife Anywhere

Photograph plants, animals, and other organisms on your own or as part of a BioBlitz. Use the iNaturalist app or to upload your observations and add them to a global database of biodiversity to support local to global research projects.

Document How Landscapes Change

Change in the environment happens gradually, so you can help tell the story by uploading a photo to Chronolog. Chronolog creates time lapses of important ecosystems to better understand how these landscapes are changing.
