These surveys can be done in any region of the country, with your club, with your class, or even with your little brothers and sisters. But if you plan on surveying bird or frog populations on private land, be sure to get permission first. Choose a safe and manageable site for your survey. You can become part of a wider survey effort, too. Every region of the country is home to a unique set of birds, amphibians, and other wildlife.
Timing is important, too.
Both surveys need to occur when the male birds and frogs are calling, usually between March and July. This site provides links to several other great sites with teacher activities and projects. Once you have learned which birds and frogs live in your area, it's time to identify them. Most surveys rely on sight and sound to determine animal populations. You've picked a site, and you've determined which species live there.
