It's migration season. The Peninsula Watershed can be a good place to see a few or more colorful birds that aren't usually around the rest of the year.
September through early October is peak migration season here in the Bay Area for multiple species of birds passing through on their way south from their northern breeding ranges to the warmer wintering grounds.
Flying long distances in a single day or
night, many will stop for a few days at various woodsy Bay Area spots to refuel
for the next leg of the journey. Some species glean insects from tree leaves or bark, while others dart out from a perch to catch flying prey in the air.
The abundance
of insect life, native trees and other greenery makes the watershed an attractive rest
area for birds on the move. If you're out on the trail, here are some typical western migrants that you might spot before they move on.
