The greater and lesser Sandhill Cranes are flying into the Sacramento and San Joaquin Valleys for the winter. To kick off the birdwatching season for cranes, the Sandhill Crane Festival is November 7-9 in Lodi. There are numerous birdwatching excursions as part of the conference.
The Sandhill Cranes are going to be in NorCal through February and you can plan your own independent birdwatching trip.
Here are a couple of opportunities in the Delta you may want to pursue:
Cal Fish and Wildlife Sandhill Crane Wetland Tours of Woodbridge Ecological Preserve
Cosumnes River Preserve viewing sites (map) includes Staten Island
These birds are really cool and you can see them from the road with just your eyes or a regular pair of binoculars. The best time is at sunset when they fly back to their nesting areas.
