Heide,

This may best be answered by somebody involved with the Puget Sound Seabird
Project. I think all of us birding around the sound, have noticed a decline
of most species. I most often bird from Dash Point Dock and for example did
not see a single Common Murre this winter. Loons, Grebes, Cormorants,
Buffleheads seem to be in normal numbers, however Scoters, Goldeneyes and
Rhinoceros Auklet numbers appear to be way down. There seems to be a
shortage of food supply preferred by certain species.
