The Global Big Day is a challenge to bird watchers everywhere: see as many bird species as possible in 24 hours. Will you join the challenge?

Thank you all for joining us during Earth Month! Just because April is almost over doesn’t mean that you have to stop helping the Earth. There are tons of great environmentally-friendly things for you to do all year.

Get ready to go outside (even if it’s just in your backyard) and celebrate nature with us this week! In honor of the 50th anniversary of Earth Day, we’re getting ready for two fabulous events – a virtual Earth Day celebration and the City Nature Challenge!
