- Quail Declines
- Citizen science efforts such as the Great Backyard Bird Count can tell us a lot about the health of our environment. For example, data from two similar projects, the Christmas Bird Count (CBC) and the Breeding Bird Survey (BBS), are vital in allowing us to monitor the status of quail and other bird populations in North America. Your input for the GBBC can also help us in this effort.

- Snow Depth Survey
- In 2001, Great Backyard Bird Count (GBBC) participants went out in force with binoculars--and rulers. In addition to recording the bird species they saw, they measured the snow, submitting some 52,000 reports of snow depth from across the United States and Canada. Researchers at the Lab of Ornithology then used this unprecedented wealth of data to create a snapshot of bird distribution and snow cover.
