NestWatch is a nest-monitoring project developed by the Cornell Lab of Ornithology in collaboration with the Smithsonian Migratory Bird Center and funded by the National Science Foundation. Sign up with your classroom to become a certified NestWatcher and help track the status and trends in the reproductive biology of birds including nesting, eggs laid, eggs hatched, and hatching survival. Record your observations on the NestWatch App. Data collected through this citizen science project is intended to study bird populations and how they may be changing as a result of climate change, habitat loss, and the introduction of invasive species. You can even create your own nest box trails to monitor birds more closely. NestWatch’s new free resource for middle school educators, called Thinking Outside the (Nest) Box, can help educators anywhere in the country create nest box trails for birds on school grounds in order to provide habitat and project-based learning.
