This new feeder combines the patented Eco-Friendly Squirrel-proof Sunset Orange Sky CafÃ© dome with a vinyl coated 1 1/2 inch wire form that allows easy access for Orioles. The bright orange dome is a magnet for migrating Orioles and Orioles that are summer residents. The dome also helps protect the jelly, oranges and meal worms from the rain and sunlight. The cage excludes Robins, Starlings, Blue Jays and other large birds that would devour all the food. Although the Baltimore Oriole is longer than our Easter Bluebirds the slender body of the Orioles allows them to easily slip through the 1 1/2 inch opening for food. It comes with a new custom made from sturdy UV stable resin (polyethylene). Meal Worm Cup that is removable for easy cleaning. The center food cup is designed and placed far enough from the wire to exclude large birds from reaching through the wire and getting the Oriole food. While the feeder works great for jelly and oranges, the fact that it can be used for feeding mealworms to Orioles is a big advantage since the mealworms don't attract bees like the jelly and oranges do. We often switch to just mealworms in July when bees seem to be the worst. Comes with 2 inch hanging chain and is pole mountable. Image shows feeder on pole mount (cord and cord lock sold separately for easy pole mounting). Lifetime warranty against squirrel damage. All plastic parts made from 100 percent recycled Plexiglas. Made in the USA.
