Update, 02 April 2008:
Well, start shopping for cigars, folks. Anna is sitting on two eggs - small, oval and off-white, about the size of champagne grapes. I couldn't get the camera above the nest to photograph the eggs owing to the parasol rain shield, and she wasn't all that thrilled with my trying, so I resorted to a hand-held mirror to reflect the confirmed egg sighting to me below the nest. I will not attempt direct shots of the eggs, but I may enlist the help of a friend this weekend to hold the mirror while I snap the desired image (I will be following guidelines set by the University of Washington Burke Museum of Natural History, which has reqested that I track the developments for their ongoing files and archives).
As the hatchlings appear, with heads above the nest rim, I'll be certain to post new images, taken from a comfortable distance of course.
All is well on this snow-free, sunny and warm Spring day in Seattle.
Cheers,
Robert
