Narrative:

We left for Corte Madera around 8:20 AM and got to the Shorebird Marsh Overlook around 8:45 AM. It was a pretty chilly day but we got to see many shorebirds. After an hour, we went to Marta’s Marsh which was pretty closeby. The first thing I saw were the European doves just chilling. As we continued to walk, it started drizzling, it felt super nice. We saw more shorebirds like the Buffleheads while walking there. Before we were about to leave, we saw a Peregrine Falcon flying behind European starlings. We were all super excited on this whole trip for our In-n-Out trip after!
