Thanks to Mon@rch, who presents stunning video at his blog, I'm trying out blip.tv for video. This afternoon, I captured this sparrow in our backyard using Megan's Kodak p850 camera. The clicking noise you hear is the camera adjusting its image stabilization. I need to turn that feature of the camera off when I shoot video!
Although I may work as an ecologist (this link is fun, pictures of me with hair!), I am by no means a birder. I make my living working with Ohio's 2300 plant species. If I were to guess, I'd say this was a song sparrow, but I'm not really sure. This is where I need your help!
