Metzger 25-Apr-2003 - I started at 9:00 A.M. Skies were sunny, and temps were in the 40's. Along the road near the corner of the parking lot, I saw a Louisiana Waterthrush. It sang several times. I watched him for 10-15 minutes. When he slowed down and walked away from me, I could see the slower, exaggerated, side-to-side, and up-and-down tail bobbing motion of the Louisiana, which is different from the quicker, choppier, shorter, straight up-and-down tail bobbing motion of the Northern Waterthrush. Also at Metzger: Ruby-crowned Kinglet, White-throated Sparrow, Yellow-rumped Warbler, Blue-gray Gnatcatcher, Hermit Thrush. In the water near the rock wall was ~230 Ruddy Ducks, 25 Scaup, and 4 Gadwalls.
