I took a trip early this morning to Hidden Valley Lake. All the birds listed were observed in a 200 yard stretch of road. It was almost unbelievable at the amount of birds in this area. It is exactly 0.5 mile from the message board at the top of the hill. This area has the lake shore on the right side and a swampy area on the left side as you drive in.
