Shorebirds also abound in winter, along with White-faced Ibis and Great, Snowy, and occasionally Cattle Egrets. Rarities have included Blue-winged Teal and Eastern Phoebe.
Nearby Sandy Mush Rd. is known for raptors; more than 15 species of eagle, hawk, falcon, and owl have been seen in the open fields and groves of oak and willow along the road.
The federal government and the state of California have established a chain of wildlife refuges from Redding to Bakersfield for the millions of birds that winter in the Central Valley every year. Merced is by far the best and most accessible; it’s a jewel that attracts birders from all over the West and adds to the joy of living in the valley.
