Help Scientists Understand What is Happening with Our Bird Populations

Hundreds of thousands of people around the world contribute bird observations to scientists each year. This information is used to reveal how birds are affected by habitat loss, pollution, disease, climate, and other environmental changes. 

Your participation will help scientists trace bird migration, nesting success, and changes in bird numbers through time. These insights inform conservation plans and key actions to protect birds and habitats.

If you enjoy watching birds, contribute your passion to help science and conservation, whether by watching birds at your feeders, monitoring nests, or sharing your sightings any time, anywhere.

SciStarter helps bring together the millions of citizen scientists in the world; the thousands of potential projects offered by researchers, organizations, and companies; and the resources, products, and services that enable citizens to pursue and enjoy these activities. They aim to:
• Enable and encourage people to learn about, participate in, and contribute to science through both informal recreational activities and formal research efforts.
• Inspire greater appreciation and promote a better understanding of science and technology among the general public.
• Create a shared space where scientists can talk with citizens interested in working on or learning about their research projects.
• Satisfy the popular urge to tinker, build, and explore by making it simple and fun for people—singles, parents, grandparents, kids—to jump in and get their hands dirty with science.
