On a beautiful sunny morning, we explored the recently publicized Thurston Hills Natural Area from the Straub Parkway side. We parked at the Quartz playground near Mt Vernon St, walked along the old Weyerhauser road, then followed the graveled trail to the top. The habitat is generally open, with open pastures to the south east and thick blackberries along the trail, getting into mixed oak and conifer habitat up higher. The birds were generally scarce. We were entertained by vociferous Wrentits at the start. We had good looks at Hutton's Vireo near the top. At the end, we were treated to a male Anna's Hummingbird doing an aerial display with a fast descent from up high ending with a pronounced click as it pulled out of the dive.
I am including Jim Regali's ebird submission, with a few of my own additions.
