If you have never been to Hansen Ranch, you are in for a treat. A leisurely walk on the levee above the pond shows the preserve's many unique qualities. In addition to heron and egret rookeries in the spring, year-round grassland species, and a variety of waterfowl and hawks in the winter, this is excellent habitat for rails which can be heard regularly as you walk along the marsh.

Wolf Ranch has seen a significant increase in bird species and diversity over the years, increasing from 58 species recorded in 2001 to 139 species reported in eBird as of April 2024. The creek is host to egrets, heron, and other wading birds and shorebirds. The restored wetlands in the winter host a variety of waterfowl. Throughout hawks, kestrel and shrike have been known to dot the telephone poles and fence posts.

Tanzanite Park is a good place for a leisurely walk where a wide variety of grassland species are possible. In winter, several species of raptors, including falcons, may also be observed along with herons, egrets, waterfowl, and shorebirds.
