Narrative:

We left campus for Mt. Tam around 8:20 AM and reached around 9:05 AM. It was a nice day, a little breezy but got warm later. We walked around Mount Tam seeing and hearing our smaller birds, our Dark-eyed Juncos and California Scrub Jays were the popular ones for that day. We went to a nice area with a beautiful view of the mountains and waited for bird action, and got to see a Merlin fly over us. We also got to see a cute yellowish Western Meadowlark sitting on the line. After 2 hours, we headed over to The Pole which was literally another part of Mount Tam. We chilled for about a good 15-20 minutes on the rocky cliff with a beautiful panoramic view. We then headed over to Mt. Tamalpais State Park – Stinson Beach with a beautiful view of the Pacific Ocean. Before heading to the trail, we got beautiful views of many Acorn Woodpeckers. We could literally hear them drumming the trees. After that we went on the trail and chilled, saw a lot of Band-tailed Pigeons, Turkey Vultures, and Red-tailed Hawks. We then took class photos before heading back. We then headed back and on the ride back Paavani and Tammy fell asleep on my shoulders on the way back, literally dislocated my shoulders LOL!
