Pearson-Arastradero Preserve is located in Palo Alto and is a great place to go birding if you live in Mountain View, Los Altos, Palo Alto, or San Mateo. The park features a range of habitats from grasslands to oak woodland, and a small lake, all of which are home to a wide variety of birds throughout the year. In the spring, many birds arrive from the tropics and make this their home for a few months when they build their nests and raise their young before heading back south in the fall.
