Magpie Nesting

I had just washed my special Koala Tea Cosy knitted by my Mother using Mohair, hung it on the line to dry. As I was standing over the sink in my kitchen I looked out and there was this Magpie pulling mohair with its beak for its nest. How smart is it. Many of my lady friends have reported similar visits from birds that peck wool drying from the clothes line.
