Ebird is a real-time, online checklist program. Bird sightings entered into ebird make a contribution to our understanding of nature when they are collected and organized into a central database where they can help complete a picture of the life of birds. By keeping track of your bird observations and entering them into the eBird database, you’ll benefit, too. You can access your own bird records anytime you want.

Project FeederWatch is a winter-long survey of birds that visit feeders at backyards, nature centers, community areas, and other locales in North America. FeederWatchers periodically count the highest numbers of each species they see at their feeders from November through early April. FeederWatch helps scientists track broadscale movements of winter bird populations and long-term trends in bird distribution and abundance.

Urban Bird Studies
Urban Bird Studies is a group of projects to help us learn more about birds in cities. Data are collected by citizen scientists across North America and in many other countries. Scientists at the Cornell Lab of Ornithology use the data to answer scientific questions about urban birds. Anyone can participate in the two types of projects--its easy and fun!

YOU CAN HELP SCIENTISTS ANSWER THESE QUESTIONS:

1. Why do city pigeons exist in so many colors?

2. What color mate does a pigeon choose?

PigeonWatch participants observe pigeons and send their data to the Cornell Lab of Ornithology, where scientists compile the information and use it to examine these two questions of scientific interest. People participate by counting pigeons and recording courtship behaviors observed in their neighborhood pigeon flocks.

Each year during the height of the avian breeding season, June for most of the U.S. and Canada, participants skilled in avian identification collect bird population data along roadside survey routes. Each survey route is 24.5 miles long with stops at 0.5-mile intervals. At each stop, a 3-minute point count is conducted. During the count, every bird seen within a 0.25-mile radius or heard is recorded. Surveys start one-half hour before local sunrise and take about 5 hours to complete.
