Today's Bird is the Common Nighthawk! They're nocturnal birds that eat mosquitoes and other bugs. Mostly, they swoop around kind of unpredictably following the flight patterns of their next meal. Common Nighthawks are all over the United States in the summer, so look out for one in your neighborhood, especially after a big rain. Look for a bird that's bigger than a bat (wingspan's almost 2 feet!) with triangular wings and white wing bars. I found this guy in the early morning (7:30 or so) at Estero Llano Grade State Park on May 24, 2012.
