Just been there while attending college tennis tournament, last week.
Stationary at the Vista Point(entrance from Eastbluff Dr. where there's a platform) you can spot
Turkey Vulture, American Kestrel, Northern Harrier, White-tailed Kite, Red-tailed Hawk.
Walk just a bit, about 0.25 mile? then you can spot Osprey.
That's 6 raptors. Harrier flies overhead.
Spotted like 59 species there, great for shorebirds, too, Willets, Marbled Godwits and Greater Yellowleg and ducks foraging right beside you in the flooded field in high tide.
Rare open fields in the area, hence attracting so many raptors I guess.
My crappy pics.
