A lot of different types of birds have been using this in our northeast backyard...
We've had a bird feeder for a few years, but this year we added a bird house and wanted to get some nesting materials.  This nesting ball has attracted so many different types of birds in our suburban backyard in Boston - they really love this.  It did come with a refill, but we haven't had to use it yet (it has been many 3 weeks now that the birds have been actively coming and taking the fur).  I recommend this.
