Cogswell 1950 Hirundo rustica 2 Aug.6 Carson City & Reno areas, Nevada - several noted at various points along US Route 395. Aug.7 E. side Boca Res., 5580 ft., Nevada Co., Calif. - 2 still present near nesting area (see July 10-11). Aug.9 W & S of Reno, 4500+ ft., Washoe Co., Nevada - about 8 seen while driving highways in -> out of Reno. Aug.18 Bear Valley, 4575 ft., Placer-Nevada Co. line, Calif. - a NEST placed on the quite smooth concrete wall of a new culvert over the Bear River held 4 large young. One adult came in and alighted on the edge of the nest; then, as I walked under the 8-ft. high culvert, all of them flew out -> up over nearby meadow. The flight of the young birds was weak in comparison to the adults, but they continued on around the meadow for at least a minute or two. Whether it was their first flight or not it is in- posible to say. A second adult bird (?) showed up when the commotion of calls from those disturbed began. The culvert, built within the last ? year or 14 mos, is much smoother than the usual nest sites selected by this species. Aug.23 W & S of Reno, 4500-4600 ft., Washoe Co., Nevada - several seen along highway in farmland areas (as usual) and over the now nearly dry Little Washoe Lake, 5020 ft. - the first there this season on any of our trips.
