Precarious Oystercatcher nest at Ballena Bay, Alameda

A pair of Black Oystercatchers has nested for years on an section of boat decking moored as a bird refuge next to a seawall. The Ballena Bay Marina was purchased by a new company and they have removed the deck. The pair resorted to making a precarious nest on the seawall.
As of this photo they had laid two eggs (one has a shadow crossing it) and a day later there were three.
I think their chances of a successful brood are minimal.
