tanzaniabirdatlas.com [1] is the official site for the Tanzania Bird Atlas project.

The project

"...is not just about mapping the distribution of birds in Tanzania. By collecting data on a monthly basis and concentrating on evidence of breeding we hope to understand much more about the seasonality of our birdlife. It is sometimes difficult for people unfamiliar with the tropics to understand how different animal and plant life cycles can be without the all pervasive effect of a harsh winter."

Birders are invited to contribute observations directly to the website.
