Entered the Bob Jones hiking, biking trail near Avila Sewer Plant. I was hoping for Hooded Merganser. From the bridge that crosses the creek saw 4 female and 2 male Hooded Merganser. They were in diving mode. Every time they went under they came up with a small fish.
About half a mile up the creek were 3 Common Goldeneye. The golf course is between the trail and the creek, but once past the golf course, the creek is easy to view. In many areas along the creek the reeds and brush overhanging the creek provide habitat for the Green Heron. I was watching a Goldeneye dive when I saw movement across the creek - a Green Heron was darting around a pile of rocks. Nearby, watching the action, was a female Kingfisher perched on a half submerged tire.
Other birds of note Steller's Jay, Oak Titmouse, and Black-crowned Night-Heron. The Night Heron was perched at the very top of a tall Sycamore (photo). I think she wanted to get away from the busy trail. 2012 is going to be a great year for birding.
