First Stop - Estero Bluffs - Blooming female Coyote Brush lined the slightly damp trail. After a few minutes of walking the brush opened giving us a grand view of Estero Bay.
Our first sighting was a female Northern Harrier silently flying, more like gliding, over the brush. She had a wide search pattern but eventually flew out of sight. Northern Harriers can be fairly easy to identify. The female is larger than the male. She is a darkish brown, while he is grey with black wingtips. They both have an obvious white rump.
Sanderlings breed in High Arctic tundra and fly down to the Central Coast for the winter. A group of Sanderlings are known as a "grain." Other birds were Black Turnstones, Black Phoebe, and two Yellow-rumped Warbler. Next stop Cambria.
Santa Rosa Creek Lagoon - Cambria - We were in birding paradise. Pied-billed Grebe, Eared Grebe aka, Fluffy Butt, Ruddy Duck, Bufflehead, Mallard, Black Turnstone, Yellow-rumped Warbler, Great Egret, a flock of Ring-billed Gull, and a ""whirligig" of Red-necked Phalarope. What a treat! photo by Mike Baird
It is impossible for me to bird the rocky coast without noticing the rocks. The impressive Cambria Slab Greywacke Sandstone is prevalent from Cambria to San Simeon. The Tafoni, the holes, in the sandstone are from physical and chemical weathering.
Our last stop was the Sea Pines Golf Course located near Shark Inlet (yes there are sharks in Morro Bay). If you are not a golfer, the only view of the pond is through wire fencing. 
Our last bird of the day was a doozy. Cathy had just gotten her binoculars focused through the wire fence when she spotted this adorable female Hooded Merganser. I've heard that many ducks are envious of the female Hooded's stylish hairdo. There are three species of Merganser in North America. Hooded is the smallest, about the size of a coot. Seeing this little beauty was a gift, as only a few winter on the Central Coast. Needless to say Cathy and I had a fabulous day of birding.
Perched on the ancient sandstone - Double-crested Cormorant, Pelagic Cormorant, Brandt's Cormorant, plus juvenile Brandt's and juvenile Double-crested. (below photo) I am quite certain the Cormorants are not into geology and had no idea the rocks they were perched on are well over 100 million years old.
On the light colored rock, were four Black Oystercatcher and one juvenile (below photo). It was a thrill to see the juvenile, as the Black Oystercatcher's reproductive rate along the Central Coast was tragically poor this year.
Feeding on the grass was a gaggle of Canada Goose and a small gaggle of Greater White-fronted Goose. (The photo was taken through the wire fence.) The White-fronted Goose has one of the largest ranges of any species of goose in the world. Now, in comparison, the Canada Goose just travels from golf course to golf course.
