In this hot, dry weather, set your lawn mower to cut on High (3 to 5 inches). It's much better for the grass and reduces the need for watering. Your lawn will stay greener longer too.
The reason? Those millions of grass blades will be tall enough to provide some shade for the adjoining grass plant's roots; and so on and so on (the roots are where most of the water is stored). Therefor, cutting High lowers the need for water and prevents grasses from drying out rapidly and dieing.
Birds of prey have talons; long razor-sharp claws which they drive deep into the prey, probably killing it instantly. Such birds are eagles, falcons, owls, hawks, kites and kestrels.
The Great-horned Owl or Barred Owl (both seen in north Texas) exert a phenomenal 250 pounds per square inch (psi) with its talons. Compare that with the pressure I can squeeze with (an ordinary male) - around 80 psi. Maybe 85 if I've had a good breakfast.
