Shorebirds have have all sorts of adaptations that allow them to exploit the fertile border between land and sea. They often have long, probing bills so that they can harvest the small critters that live in the wet sand and mud at the water's edge.
So how does one explain this lot? We were out biking with a ranger from the East Bay Regional Parks, and I spotted these doves, picking their way along the shore between Alameda and Bay Farm Islands. There were four stark white doves, doing nothing I've ever seen a dove do.*
Clearly, there's a magician somewhere in the Bay Area who is looking for his doves.
And then there's the little matter of bay side crows. We see a fair amount of crows on rocky shorelines. They look so comical, but are probably doing very well for themselves. Crows, after all, are highly intelligent omnivores, ready to explore any possible food source.
*We won't talk about the less romantic relative of the dove, the urban pigeon, who seems to have a cannibalistic streak, and can often be seen eating discarded fried chicken.
