This Kaytee Songbird Hopper Feeder is made with durable weather and UV resistant materials that reduce fading and cracking. The squirrel resistant sliding lid opens wide to make refills a snap. Ventilated trays provide for better air circulation and drainage, keeping the seeds fresh longer. The hopper feeder holds up to 6.5 pounds of wild bird food so you can enjoy more birds for longer period of time before refilling. A nylon coated steel cable allows for easy hanging.
