Dana. 1940. Sparks Lake, Deschutes Co., Oregon. 5). July 13. skinned some birds, & prepared formalin specimens. Sibley & I set out a short trap-line for chickarees and golden-mantled ground squirrels. Saw @ a few lots at dusk. Saturdays and Sundays find Sparks Lake more populous than usual, due to an influx of fishermen from Bend. Weather clear, cool, some wind. July 14. collected 16 DANA aurora aurora, 2 Bufo, 1 Ceromyzus, and 2 hairy Woodpeckers, one of which I gave to Sibley. Set out 22 small traps in the p.m. The car developed engine trouble, the repairing of which took up most of Sibley's time. The DANA were collected between 8:00 a.m. - 9:30 a.m. (7), and 3:05 p.m. - 3:35 p.m. (9). All were taken from the creek outpockets mentioned in notes of July 13. The Bufo were collected, one in the creek in front of camp, the other in camp itself. While collecting in the p.m., flushed either a Lincoln or Savannah sparrow from a nest containing 3 eggs. Nest of fine grasses, on ground, at edge of creek flouring into Sparks Lake. Remained 30' from nest for minutes, but bird did not reappear, so I left. Saw spotted sandpiper and 1 young, unable to fly. Also 1 Thamnophis, which escaped into creek & hid under overhanging bank, and I was unable to locate it. Sibley added the following new birds to our Sparks Lake list: Cassin Vireo, Warbling Vireo, Ruby-crowned Kinglet. Hunted lots at dusk (unsuccessfully). July 15. collected 8 Oregon Junco at camp, & feeding from ledge-polestul near lake, 18 DANA aurora from Satan Creek
