Arrowhead Marsh- Martin Luther King, Jr. Regional Shoreline
We went to Arrowhead Marsh which is next to the Oakland Airport. The sky was clear with very little cloud cover and the temperature was in the low 60's to mid 60's. The tide was high so most of the Spartina was submerged. This meant that we saw a lot of rails. I was in Jim and Coleen's group this week.
Cool Stuff:
TONS of rails. A dozen Clapper Rails, 3 Virginia Rails and about 10
sora. Amazing!The ring billed gulls will drop mussels and clams onto the walkway to
crack them open.
Stuff that we missed
- Normally there are Peregrine Falcons
A few years ago they saw a Loggerhead Shrike (a passerine bird that
impales it's prey on thorns or barbed wire)Burrowing owls are known to live here but they haven't been seen for
at least a year

Didn't see many raptors today. This pair was circling a building off in the distance later in the day. Maybe it was cold so there were fewer thermals to ride.

TONS! of these guys were out. It was high tide so the water flushed them out of the Spartina and reeds. We saw about a dozen of them. They are roughly the size of chickens.
