R-E-Johnson 1969 Journal March 20 Boulder & Nederland & vicinity to Denver, Colorado, to Glacier Lake & back, then up the Cariboo Rd until drifted snow prevented passage; then checked the 3 sites in Nederland again (no birds) and stopped at the Washateria at 9AM to bring these notes up to date. I talked to the lady that runs the Washateria & while I was in her house (9:20 AM) a flock of 40 flew up & landed on the wires. They flew down to the ground, then back to the wires, then cast to the wires above the next house, then to the ground in front of that house & back to the wires again. They continued in this manner back & forth between wires & ground in front of the 2 houses for 15 minutes & then flew off to the west. They were mostly L.tephrocotis, but there were a few littoralis & at least one australis. Probably: 85% tephrocotis, 10% littoralis, 5% australis. The lady said they hadn't seen many for about a week & the larger flock that we just saw was the largest they'd seen this week. She said they hadn't put out any new feed (there was still some old seed visible on the ground & bird feeder) in several days since it appeared the birds were largely gone now. She usually get large flocks of blackbirds next. So far only a few have shown up this year. She said the rosy finches usually come very early in the morning & again late in the day just before dark. She said they get fewer now than several years ago, perhaps because a number of other people in the area feed them too, thus
