The morning insect hunt, from perches in the lonely valley oak near Road F and Trail 15. Apologies if these are not in sharp focus: I was lucky to even get the bird in the frame! To see the whole sequence of swallows in flight, see the nearby collection. I originally identified this as a Violet-green Swallow (Tachycineta thalassina). Phil Leighton writes: "You might check Northern Rough Wing Swallow for your flying swallow. The Violet Green Swallow should have bright white, with a clear edge extending above the eye as can be seen on your perched swallow."
