Bill Maynard, a botanist and former high school biology teacher, has worked for various government agencies from Alaska to South Florida and for The American Birding Association. He discovered the 87,000 acre Chico Basin Ranch to be the perfect natural laboratory to study and photograph birds, dragonflies, grasshoppers and other insects.

In September, a walk in the cholla cactus will often result in seeing two thrasher species.  The migrant Sage Thrasher is is dark gray with a shortish straight bill and the resident Curve-billed Thrasher (photo) is easy to find except when it is nesting.  The curve of its bill and larger size than Sage Thrasher make the two species fairly easy to separate, plus a Curve-billed Thrasher has large breast spots than Sage Thrasher breast spots.
