3	Santa Barbara	500

So close yet so far!

Pt. Loma area(down to Cabrillo) really is exceptional. Maybe because it's along migratory path.

The reason why SD boasts the most bird species seen, trumping Los Angeles!

However hard LA county experts like the Garretts(not related), Feenstra, Dowell, Tiller etc. try, SD experts like McCaskie, Lehman, Bruin, Nunn, Sadowski, Christensen, etc. will invariably discover yet more species! Even a novice like me found an alternate plumage adult male Cape May Warbler at Famosa slough.


Kern county seems quite exceptional as well: should explore the area!
