When out for a walk this morning I came across a treasure!
It was laying at the base of a tree, discarded by it's previous owners. Looking at the bits of remaining, light blue (possibly speckled) shell fragments, I'd say they successfully raised a family.
I'm not up enough on nest/shell identification to speculate what type of bird may have created this nursery, but it sure has a lot of interesting inclusions.
One of the interesting bits is a clearly labelled, cellophane, "Allan's" candy wrapper. There are also other bits of paper and plastic right alongside the more traditional building materials like straw, bark, leaves, mud, and sticks.
I can't wait to show my granddaughters! Maybe they'd like to take it to school for Show and Tell and then perhaps donate it to the school for other classes to see as well.
It's very sturdy and well built. I might take it to the wild bird store and see if they have any thoughts about what type of bird may have built it.
