We watched a roadrunner stalk and kill a mourning dove. See subsequent photos. The roadrunner repeatedly thrashed the bird against the ground. The roadrunner walked off some distance after killing the dove. Great-tailed grackles kept a respectful distance and the roadrunner rushed at one or more when they approached the expired dove. We returned hours later and the carcass was still in place. If I hadn't seen this myself, I would have thought for sure a Cooper's Hawk was responsible and perhaps got scared off the carcass. @karakaxa @noahgaines @featherenthusiast

Very distinctive little "bottle pore" liverwort, or balloonwort, growing in large quantities on the flat bare compact soil along the trail that leads off of the main trail and up into an adjacent neighborhood. The larger green plants are females but if you look closely you can see the diminutive males growing amongst them with tiny dark reddish purple "balloons."
