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! This is a different approach, perhaps the same or perhaps different from previous swallows, labeled swallow D. Near the lonely valley oak on Road F, 7:52:45 am: D. 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." So I am providing Phil and you all, these many views, of the same and possibly different swallows.
