This extremely versatile window feeder by Droll Yankees is simply called “The Winner” or W-1 for short.  Cousin to the X-1 “Seed Saver”, the W-1 brings all the bells and whistles of a high-end platform feeder right to your window.  It has a height-adjustable dome which allows you to limit the size of the birds coming to indulge.  The large feeding tray is perforated for drainage and is perfect for feeding mealworms to Bluebirds or Sunflower Meats to Cardinals.  Perhaps the best feature of this versatile feeder is how it attaches to your window.  The three suction cups mount a bracket to the window - the feeder may effortlessly be removed from the bracket for easy cleaning, filling and maintenance.  We agree with Droll Yankees: this one truly is a Winner!  Made in the USA.  Lifetime warranty.
