Thanks all for the comments. Peter, I have not seen any shorebird chicks yet. Unfortunately I won't be visiting this particular beach (Alameda south shore) any time soon so those that hatch there will probably have flown before I visit again.
Stuart, I'll be visiting the mountains in northeastern California for the next two weeks, and I hope to come back with many more photos.
Andy, the DMR has made the 560 my most-used lens. In particular the image quality above ISO 200 has made a huge difference. The rubber thumb dot on my 560 was new in 2002 and because of the DMR I've almost worn through it
