Red-necked Stint, adult, Arroyo Laguna lagoon, San Luis Obispo County, California, 3 Jul 2017, Tom M. Edell

Observation details

Adult found by Roger Zachary this morning. In the field the most notable feature on the bird was the rust colored throat bordered below by dark streaks that were less extensive than on the WESA and densest toward the shoulder. The rust color extended on to the side of the nape and lower face and did not extend into the dark eyeline that was most distinct between the eye and the bill, but weaker behind the black eye. It was similar in size to WESA, but had a shorter all black bill. Like the WESA, it was otherwise white below through the undertail coverts. It appeared to have a slightly wider supercilium than the WESA and darker crown and back. There were rust colored feathers in the scapulars. Otherwise at rest the flight feathers appear dark with pale fringes. The feet and legs looked black. Looking at my photos, I can see that the primaries extend slightly beyond the tip of the tail and there are thin sparse dark streaks on the side of the vent area and a few visible on the flanks. Some of the breast streaks appear triangular in shape and point down the breast. The chin pales from the rusty breast and appears white at the base of the bill. The crown is largely composed of dark brown streaks that are broad over most of the crown, densest in the forecrown, but thinner and more noticeable above the white supercilium. There are scattered rusty feathers visible on the back but no discernible pattern to them. There is also some pale rusty color on the sides of the crown of the supercilium. The bill is somewhat thick at the base, somewhat blunt at the tip, and droops slightly at the tip. There was no webbing between the toes. After viewing and photographing the bird for about an hour, two killdeers flew calling over the creek mouth flushing the peeps. The birds had flushed a few times earlier without departing, but this time they gained altitude and flew off over in a general southern direction. One and then three WESA came back and quickly departed. I’m told, the RNST never returned. Photos and video (https://www.flickr.com/photos/tedell/35533454092/) taken.
