From the site:
Download Mozilla Sunbird (Mac or Linux)
"Sunbird is our standalone calendar application. It doesn't need another client application to run at the cost of a larger download and higher memory requirements. Because of its standalone nature, Sunbird does not offer any kind of tight integration with an e-mail application, such as Mozilla Thunderbird."
