Visitors:Many hikers came and went during my time birding. Maybe it was due to me
having a scope, binoculars, a Rocky Mountain Raptor Program T-shirt, and
wearing my golden eagle hat that nobody asked me questions about my
activities.�
Weather:The winds aloft suggested by
earth.nullschool.net were light from the West,
the same as yesterday when I had no migrant raptors, so I thought I'd give
my muscles a rest as my peroneal and sartorius muscles have been cramping
at night because of the unaccustomed exercise of climbing 294 ft to the
watch daily carrying around 25 lb. of equipment, food and drink.
I got a pleasant surprise email in the evening from Zak Hepler who had
joined us last winter for one of our DFO winter raptor ID trips, and who
had gone up to the watch. This is his report:
The beginning of the shift started with winds blowing slightly South, but
turned to winds blowing to the West by 9 AM DST. Sky conditions were still
hazy from the wildfire smoke. The city of Denver was mostly lost in the
haze, but the North and South Table Mountains could be seen.�
Raptor Observations:Within the first 30 mins, I had seen 2 RTHAs use the same woody ridge that
is found just South of Mount Zion. One soared and landed in a pine, but the
other gained altitude and went around the eastern edge of the hills;
keeping the ridges on its right. Later, 2 AMKE flew by both heading South
in frantic falcon fashion. Were the AMKE migrating? Hard to say. Later, one
juv RTHA was able to gain altitude right above the Watch! I watched the
bird circle, and soar, starting only 30m above my head. The banded tail (no
red) helped determine the age. This bird, once proper altitude was reached,
headed North. The Western winds did not help the raptor sightings.�
Non-raptor Observations:In total, 5 different paragliders were seen this morning. The
raptor-adverse winds moving from the West helped the brave gliders take off
and enjoy the hazy morning. With my binoculars I could see that the people
were having a great time and their experiences were being recorded with a
'selfie stick'. These gliders started taking off around 10 AM near the
windsock to the NE of the Watch. Before I left, somebody started playing
tribal music around 10:40 AM. Native American drumming and chants sung and
played very loudly. Sounded like a ceremony. The music was played live.
Pretty neat. My hawk mentor/friend, Ajit, was not present today. Much to my
dismay.
BTHU 3, WOSJ 2, AMCR 2, BARS 2, PISI 2, LEGO 2, SPTO 3.
Predictions:Earth.nullschool.net predicts light WNW which which may result in the same
lack of migration as today, but Tuesday has winds streaming down from the
north, blowing from the NE at the location of this watch, which could be
favorable.
