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
