Find more than 300 species at a restored estuary just 20 miles north of San Diego.

One of my favorite birding spots in San Diego County, the San Elijo Lagoon Ecological Reserve is a stopover for masses of migrating shorebirds in fall, a wintering refuge for all kinds of waterfowl, and a nesting area for several endangered species.
Birding here is like stepping back to an earlier time when freshwater creeks still met the ocean in peaceful estuaries, and Snowy Plovers and Least Terns gathered and laid their eggs undisturbed.
Eventually, urbanization took a toll. By 1887, dikes and levees had been built to make roads, duck-hunting ponds, and sewage settling ponds. The mouth of the lagoon backed up, and water quality suffered; the daily tidal cleansing of ocean waters could not breach the sand bar that formed at the inlet to the estuary.
Recent periodic dredging of the lagoon mouth by county, state, and U.S. Fish and Wildlife Service officials has restored the estuary to its naturally healthy condition and made it a prime example of how habitat restoration can bring an estuary back to life. The extraordinary number and variety of birds that can be observed now, compared to 20 years ago, makes the place extra special. — Joan Easton Lentz
