I know there are several frog and toad species at the Mason Pastures, and see and hear a different one at the ephemeral dirt tank at the north end today, but telling apart this impressive variety of frogs, toads, treefrogs and spadefoots of these Sonoran Desert lands is mostly beyond me or at least is beyond my study time.

All the flycatchers seem to have young ones chasing them around and pestering them for ever more insects. The adults look like exhausted parents do everywhere.The Stockpond Gray Hawk, that most Mexican of our Border birds of prey, comes bombing with great agility through the low branches of the mesquite woods, and the small birds panic and chatter or else they go silent–but I do not read that this hawk eats much other than lizards. The passerine reaction must be born of those birds’ experience of living in this same woods with the Cooper’s Hawk, who comes through terrorizing and picking off its lunch in much the same hunting mode.
