A tiny unhatched hummingbird is getting in the way of -- but not stopping -- a project on the Richmond-San Rafael Bridge.
The discovery of a nest and egg in a tree is stalling the start of upgrades on the bridge, officials said Tuesday.
The species, Anna's hummingbird, is protected under the federal Migratory Bird Treaty Act that forbids the removal of the egg and offers other protections to birds.
The nest — about half the size of a fist — was discovered about a week ago when work was set to begin.
It was found on the Richmond side of the $70 million bridge project, in one of about two dozen trees that were to be removed to widen Interstate 580, officials said.
