Birding at Harbor Park is an all-year activity. The historic park list exceeds 300 species and since its restoration & reopening in July of 2016 the count is over 160. The large open lake is attractive to ducks, gulls, terns, rails, occasional pelicans and cormorants, and more. Nesting boxes near the ranger station at the southwest corner of the lake attract Bluebirds in the spring and summer. Marsh wrens can often be heard singing in the reeds on either side of the dam at the south end of the lake. This is one of the best areas in the South Bay to see this secretive bird.

In summer, many birds use the park for nesting. Both Hooded and Bullock's Orioles are found here, along with Cassin's Kingbirds, Tree and Barn swallows, Marsh wrens, Common Yellowthroats, Pied-billed Grebes and more nesting species. Check the area to the south of the dam for possible nesting Black-necked Stilts, Killdeer & Sora.
