A new citizen-science project has kicked off this week called the Global Amphibian Blitz. It is like eBird in that it hopes to gather large amounts of distribution data via a network of observers around the world. Also like eBird it is a good way to store your observations for your personal records.
Another interesting feature is the ability to upload photos of your observations. This is useful if you are unsure of a species identification. This allows other people to weigh in on the correct species ID.
The first day in operation the database recorded observations of 154 species from 18 countries.
