Coastal Bird Count--The results are in for the Christmas bird count done in the coastal areas of the county. The local effort was sponsored by the Sea & Sage chapter of the National Audubon Society.

A total of 171 species and 51,356 individual birds were sighted. Here are the five most sighted species and the region in which the most sightings were recorded:

* Western sandpipers, 5,854 individuals counted. They were seen most often on the west side of Upper Newport Bay and the Costa Mesa area.

* Ring-billed gulls, 4,634. Most common site for these birds was Mile Square Park in Fountain Valley.

* European starlings, 3,642. The birds were seen the most in Huntington Central Park and its surrounding area.

* California gulls, 2,426. The east side of Upper Newport Bay was where these birds were found the most.

* American coot, 2,136. Hundreds of these birds were spotted in almost every section of the coastal count, but Mile Square Park had an edge over the other areas.

Wetlands Tours--Guided public tours of the Bolsa Chica wetlands will be held Saturday. The tours, sponsored by the Amigos de Bolsa Chica environmental group, will depart from the Bolsa Chica Ecological Reserve every 20 minutes beginning at 9 a.m. The last tour will depart at 10:30 a.m.

Participants are asked to meet at the ecological reserve on Pacific Coast Highway, about half a mile south of Warner Avenue, across from Bolsa Chica State Beach.
