Encouraged by Marcy's reports, I finally got to Oxbow Lake 
(first visit this year).  Started pretty late (4:30 pm), but 
gradually some good variety started to appear.  Ducks 
included AMERICAN WIGEON, NORTHERN SHOVELER, GREEN-WINGED 
TEAL, and HOODED MERGANSER.  Other highlights included an 
EASTERN PHOEBE and a singing PINE WARBLER (also seen) close 
together at the southwestern tip of the lake.  A HERMIT 
THRUSH was difficult to see in the thorny bushes nearby.

Full eBird report follows:

Observation date:    3/16/10
Notes:    Short walk at the lake (distance is one way on

distracted by the swallows.  Telescope needed for most of 
the ducks.
