DUH!!! So do I feel the dummy not looking under Knot!!!
I was in Tierra del Fuego in Feb. and birding with young Chilean couple who
were helping USFW band Red Knots on the Pacific coast there. They had
recaptures with bands from both Del Bay and Brazil where they were tagged
on way S. BUT, there has been a significant decrease in the birds showing
up in 'wintering' grounds in TdeF.
Scott Weidensaul in his great book Living on the Wind has a chapter about
the rise and fall of the shorebird/horseshoe crab populations that use the
Deleware Bay. Historically (late 1800's and early 1900's ) there were not
reports of this great feeding frenzy that we see today. Of course, it is
not as simple as here today, gone tomorrow but the chapter (and the book)
are great reading.
