Residents of interest include Golden Eagle, Prairie Falcon, Burrowing Owl, Greater Roadrunner, Say's Phoebe, Rock Wren (in rocky ravines), Loggerhead Shrike, and a chance for California Condor. In winter, look for Ferruginous Hawk, Long-billed Curlew, and a few Vesper Sparrow among many Savannah Sparrow.

This road is a key part of the King City Grasslands Important Bird Area. For about the first 9 miles from King City, it is in Monterey County, but thereafter crosses the San Lorenzo River (the river can go dry in summer) into San Benito County for about 7 miles before crossing back into Monterey County just before the little town of Lonoak.

Lonoak Road is a two-lane paved road from King City, winding through grazed grasslands and around barren hills, to the tiny hamlet of Lonoak at the north end of Peachtree Valley. It is typically not too busy but one must use pullouts and wide spots to stop to bird. The short-grass grasslands may be green after winter or early spring rains, and have wildflowers in March-April some years, but will be barren brown in summer. All the land on either side of the road is private ranch-land. Still, it sometimes feels like you are driving through South Dakota in the 1950s. Drivers need to use caution, though, for some fast cars or motorcycle clubs, or for large trucks with cattle or feed.
