Two web links have recently come to my attention.
A friend sent me this weblink about the UK's oldest Arctic Tern. The record breaking migration flight of a Red Knot was posted by a birder to the Michigan birding list.
I often think of bird migration as one of the wonders of the world. In each case, both birds have had amazing migrations. In the case of the Arctic Tern, its migration occurred over the course of its incredible length of life. In the case of the Red Knot, its migration occurred in a single flight over the course of many days.
