I know some people go birding so someone might find this neat. This weekend running Friday-Monday is the Great Backyard Bird Count! And this year for the first time, lists can be submitted through http://ebird.org for people internationally who would like to join in.
It is pretty much just what it sounds like: one weekend a year, to get as many people as possible to count birds for at least 15 minutes and submit a bird count list.
All you have to do is watch for birds--could be anywhere, at your feeders in the yard even, you don't even have to leave the house--for at least a 15 minute clip, and submit a list of what kind of birds you saw and how many of each.
