The Eastside Audubon Society (EAS) had its 2010 CBC on Saturday, Dec. 18. It was cloudy and windy from about 8 a.m. to 10:30 a.m., wind quit & some clearing until 2 p.m. when wind with rain came back, temperatures of 42-48 F. Many of the fields were flooded in the Snoqualmie Valley due to the recent heavy rains. Some roads had only opened the day before.


We had a 50 people covering eight areas (the CBC circle is centered just south of Beaver Lake in Sammamish). We had one backyard bird count report and ended up with 93 species which includes 3 seen during count week. This is our third highest total, compares to a high of 95 in 2008 CBC. The total of 13,035 birds compares to a 10 year average (10YA) of 14,757.



Highlights and major changes in the bird counts over the past 10-15 years include:
