Crested Caracara is a falcon relative. Unlike the falcon it prefers carrion to capturing prey. Interestingly, the Caracara will land and walk to capture a prey rather than swooping in on it.
Sort of a cross between a bird of prey and vulture. Some sources suggest this may be the bird on the Mexican flag and not the Golden Eagle. Central Texas is the northern edge of their range which extends all the way south to Patagonia and Tierra del Fuego. Not typically seen in the US outside Texas, Arizona, and Florida.
