We have White wings visiting our feeder. A few years ago they were considered endangered, so Texas Parks and Wildlife had an employee that dedicated his time and expertise to studying the demise the White wings. Unfortunately for him, the White wings did just fine on their own, and are now numerous, so he had to find another research opportunity. Here are two White wings on a branch in our back yard, ready to drop down on the platform feeder. They are called White wings because of the white feathers lining their wings. Makes sense, doesn't it?
