The Purple Martin. This bird brings back many memories as I drove from our home in St. Louis to visit my parents in Illinois. We would pass through this little town called Griggsville, better known as the "Purple Martin Capital of the Nation". This little town of 1,200 people claims to house more Purple Martins than anywhere else in the U.S. The Purple Martin is famous for eating 2,000 mosquitoes a day! Now, that's something worth celebrating!
