If it's goldfinches you want to see, the Nature's Way Thistle Seed Feeder is an attractive and highly durable choice for serving the thistle seed these birds crave. Specially designed feeding ports are tailor-made for finches while keeping squirrels out. You know that finch feeders need to be cleaned frequently, so how cool is it that this one is dishwasher safe? The patented Twist and Clean feature makes it easy to disassemble this feeder for cleaning. The Even-Feed baffle system ensures that even when seed is running low, all perches remain stocked with seed, allowing more viewing opportunities for you! Rust-free metal perches and roof complement the stay-clear polycarbonate tube.
