This bird house is the perfect size.  It is amazingly durable and strong.  The material it is made of is strong and non-breakable.  This is honestly the best bird feeder I have ever owned.  It has see through windows on each side where you put the seed so you can know when you are low on bird seed.  The top roof lifts off easily to add more bird seed when needed.  I love the natural green color of the feeder as it blends in well hanging in my front yard tree.  This is the only bird feeder I will ever need as I expect this one to last many years or forever because of how well-made it is.  I highly recommend this bird feeder to all bird lovers.
