A pair of Bullock Orioles built this nest last year in our elm tree. I listened to the babies when I hung out wash. Then one day they were gone but left this nest behind. It blew down in a bad snow storm this winter. They used hay bailing twine and shredded it somehow. The colors are yellow, blue and orange. The entrance and inside is lined with snippings of John's hair that I throw out on the lawn for the birds to use. It is a bag like structure and woven better than the best of human weavings. It is a work of art. I love looking at and touching it.
