Window Bird Feeder includes a Goldfinch thistle bird feeder, clear dome above and a strong tripod window hook. The Window Bird Feeder for Goldfinches is an all metal finch bird feeder that is 17.5 inches tall. This thistle feeder has internal hollow cones that help retain seed along the entire feeder length. The great advantage in keeping the seed dispersed over the feeder permits feeding many wild birds at the same time. Another plus is that squirrels don't like thistle and won't bother this feeder. The clear dome has a 13" diameter to offer good protection from the weather. They are both supported by a strong wire Tripod white metal frame that makes it very tough and stable. The three strong suction cups hold it in place on your window. Best of all is you get to see these Goldfinches up close!
