Dullion 1947 Buteo ridens virescens - 1 Aug 17 Big Lagoon, Humboldt Co. Calif. - I seen standing on sand bar along Maple Creek near "Mink Channel" (see journal p. 124). At flew further downstream, again settling on a sandy area along the U loop of Maple creek N of Mink Channel. As it flew from this position & collected IT (7:05 a.m.). Summary - This species was encountered & only in the coastal area around Big Lagoon. I believe that we should have found it at Willow Creek along the Trinity River but we failed to do so. In the Big Lagoon area it was a bird of gravel bars along Maple Creeks, seemingly independent of a brushy stream margin. A single bird was seen daily along the portion of the stream flowing by camp.
