Subject: [COBOL] Hart Mountain CBC on December 20, 2017
The Hart Mountain CBC took place on Hart Mountain National Antelope
Refuge and adjoining parts of the Warner Valley on Wednesday, December

Refuge manager Laurel Kullerud organized the count and got us set up in
the bunkhouse on Tuesday evening, despite an incoming storm with high
winds that made walking difficult. The wind tore a sheet of 3/4-inch
plywood off of the winter housing for the air conditioning unit. It went
cartwheeling out into the sagebrush, but we chased it down and secured
it back where it belonged, adding a few boulders and a log to weigh it

Snowfall overnight produced drifts that were up to 18 inches deep in one
spot that Clay Crofton managed to step into while hiking down Rock Creek,
but generally less than a few inches on the main roads. Teams that worked
down in the Warner enjoyed mostly calm conditions and temperatures that
climbed up to 36 F by noon, but teams up on the plateau above the
escarpment reported breezy to windy conditions, with snow flurries in
the afternoon.

Down in the Warner Valley, several lakes had areas of open water, but
waterfowl were scarce, perhaps due to colder weather earlier in the
month. Due to windy conditions we didn't make any serious owling effort.

Despite this we found 37 species on count-day, plus at least four count-
week (cw) species as noted in the list below. Species that were new for
the checklist are indicated by (*).

A few LESSER GOLDFINCHES have also been visiting a feeder in the Warner
Valley recently, and might yet make it into the count-week list. A
probable PINK-SIDED JUNCO has also been seen; in addition to pinkish
flanks it appears larger than Oregon Juncos in the same flock, and has
dark lores. We're still hoping for photos to confirm this one.

Volunteers included Clay Crofton, Pat Grediagin, Jeff Picton, Jöelle
Fournier, Zachary McCoy, and Martha Geier. Thanks to all who made the
trek despite conditions that raised whitecaps on Lake Abert. Special
thanks to Laurel and Zack for helping us all get set up in the
bunkhouse on Tuesday evening, and to Jöelle and Zack for sharing their
feeder birds.

Happy winter birding,

Joel Geier
