This particular Mockingbird was watching me work in the front yard, singing his heart out from the top of a shrub in true Mockingbird style. These birds are anything but shy; they often choose prominent perches from which to sing, and flash bright white wing spots as they fly. They're also tenacious little birds, not afraid to confront other birds, even mammals like house cats, in defense of their territory. They don't hesitate to chase away other Mockingbirds (especially when a female is defending her nest) and readily give chase to larger birds as well. Yesterday, I watched a Mockingbird noisily chase away a larger Yellow-billed Magpie.
