Black Lives Matter demonstrators halted traffic Monday afternoon on the five-lane westbound span of San Francisco’s Bay Bridge, the Guardian reports, chaining themselves to their cars.

The osprey, Pandion haliaetus, is a bird of character. The ancient poets knew this, and the Maryland Transportation Authority is discovering it the hard way. Last week, a pair of ospreys decided to build their nest on a platform overlooking the approach to the Chesapeake Bay Bridge, where the MDTA keeps a traffic camera.

The container ship Cosco Busan struck a tower of the Bay Bridge in San Francisco in heavy fog. Traffic was not affected and the bridge seems to be fine, though the cargo ship was leaking oil and had a 100-foot gash visible on the side. (Photo by San Francisco Chronicle/Michael Macor)
