Plectrophenax nivalis
June 13 Pintzeger - 1 pair on Ridge II - west of camp,
June 14 (At least 3 pairs on far ridge (also called
Ridge III & Beer ridge)
June 17 Several 8" bunting were fluttering about
the cliff just below bar on which tent
is situated. This would be a good nest site
probably they nest here.
June 20 8" singing from bluff downstream from
camp during afternoon. Seen them again
at 7 this evening.
June 23 Nest with 5 young - dark grey down
no pin feathers, 2-3 days old. Under
rock slab on Ridge II - west side.
Nest reached by a small opening perhaps
3 meters square + passage 16-18 miles
long to tiny chamber just nest size.
8" Bunting chased a female Longspur who
was foraging within 50 feet of nest. Saw
her later chase a 8" Longspur & later
still the female again. The Longspurs
were foraging along the ridge all day.
Fifty feet radius seemed to be the female's
territorial range because beyond this she
paid them no heed. Did not see male chase
them at all.
June 24 At nest on Ridge II. Noted several other cheers
of Longspurs by Snow Buntings. When I
put up camera tripod, 8" landed 20 feet from nest
