Just visited a site I enjoy called Home Biology and guess what I found?
Information about ZipcodeZoo.com. What a FUN site! It uses your ISP address to determine where you live and give you information on local wildlife, weather, endangered species, etc. Though I'm not going to vouch for the accuracy of your location. You might have to tweak that once on the site!
What a great resource for nature study! Go to there. Have fun!
