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.

Visitors:
Many hikers were interested. When I got there a young man said it was a great view, and I said that's why we chose this spot for the hawk watch with unobstructed views in all directions. A young couple were interested in what I was doing and we discussed counting migrant raptors, which they thought was Awesome. We discussed the particulate matter in the air and ozone levels. He asked if I were a geographer, and I said hawk watchers need to know meteorology as well as local air quality to know when to wear masks. He said he worked with children and some days they wouldn't allow them to play outside. I showed them two distant TVs which I could see with binoculars, and suggested they could probably see them naked-eye because of their youth, and sure enough they could. That's so cool, they said. An older hiker asked me what I was taking pictures of, and I explained that this was a 'scope, and what I was doing. Two women with him asked numerous questions about raptor migration and why they do so, flocking rehavior of raptors, use of thermals by raptors, and the 14 species of raptors we could see here, and that wherever possible I tried to separate them as to adult/immature and male/female. Two young men I could see were listening intently, and after the 3 hikers went off, the young men said that they found what I had said was fascinating, and we discussed it further. A young man who had just moved from Texas 3 days ago, doing postgraduate work in geology at the School of Mines, the engineering school in Golden, Colorado, asked me if this was a trail going NE down from the top of Mount Zion. I said it probably led to the windsock and the spot where paragliders take off from. On his way back we chatted for a long time about my interest in geology and paleontology- I told him about the importance of South Table Mountain being the first place in the world that the K-T (now called K-Pg) boundary was described, which marks when the asteroid hit the earth that ended the reign of the dinosaurs, where the first T.Rex tooth was found 40 years before the first T.Rex fossil was identified, so they had no idea what it was. I realized that my function at the watch when there are not many migrant raptors is to be an educator and get people to open their minds to hawks and their migration.

Weather:
The high was expected to be 100�F, which I took to mean that there was going to be less smoke from wildfires in the air, and there was minimally less smoke, though there was a layer of smoke covering Denver downtown which I could barely see. PM <10 and PM <2.5 were both in the moderate range, and ground level ozone was high. Because of the higher cloud cover of altocumulus floccus stratiformis and altostratus it was intermittently cooler when their shadows came over the watch. By 10:00 a.m. MST the local winds from the ENE overpowered the winds from the West, which I could still feel on the west side of the top of Mount Zion, showing it was still there.

Raptor Observations:
I counted no migrants today though I scanned with binoculars assiduously and systematically. However there was a lot of local raptor activity and sightings: adult GE 1, CH 2, RT 8 including 4 together, TV 10, the 1st of which was aloft at 10:08 a.m. DST.

Non-raptor Observations:
Common Nighthawk migrants 3, Rock Wren 1, WBNU 1, AMCR 3, CORA 1.

Predictions:
A 30 percent chance of showers and thunderstorms, mainly after 3pm. Areas of smoke. Partly sunny, with a high near 96. West wind 5 to 8 mph becoming northeast in the morning.

Visitors:
A couple from DC visiting theeir son in Denver were curious about what I was doing with my binoculars in scope, which I explained.

Weather:
Earth.nullschool.net showed sinuous streams of wind coming down from Canada through the area of this watch, which would be good, if raptors were migrating, creating a good channel Southward. At the watch the winds were from the ENE caused by local factors which usually result in winds every afternoon from the East, viz. Plains Heating: Intense daytime sun rapidly bakes the Denver metro area and the lower Golden-area terrain, making the air warm, light, and buoyant. Anabatic Upslope Flow: As that warm air rises over the lower landscape, it creates a localized vacuum effect, drawing air from the east (Denver/plains) upslope toward the mountain crests. Ridge Lift Interaction: The steep topography of Mount Zion and Lookout Mountain acts as a ramp, enhancing this upslope pull by afternoon and overpowering lighter synoptic morning wind patterns. The smoke from wildfires was minimally less than 2 days ago but high enough that there was a 10� layer of white smoke above the ground almost blotting out Denver downtown. Address relatively cool in the'80s and '90s because of the microscopic particular pattern the smoke dissipating the Rays of the sun from hitting the ground.

Raptor Observations:
Migrant Raptors: 2 Redtails, a CH and an AK (the AK took a swipe at the CH in flight) today that I could find. Non-migrant raptors sightings: a Prairie Falcon missing its central retrices, seen to the NW at the level of the ridges flew south, dropped into the trees on the North face of Lookout Mountain. RT 3. TV 4. I wondered whether there was any information available weather raptors or other birds would migrate through smoke. I looked it up and found that they may sit it out, fly through the foothills where there may be less smoke which they were not doing here, or fly above the smoke up to 12,000 ft. Looking at the Soaring Forecast of the NWS https://forecast.weather.gov/product.php?site=NWS&product=SRG&issuedby=BOU, since the trigger temperature of 89.1 F/31.7 C was reached by 12:00 p.m. MST, the Thermal Soaring Index was Excellent, the Maximum rate of Lift would be 1484 ft/min (7.5 m/s), and the Maximum height of thermals would be 20479 ft MSL (15114 ft AGL). Smoke would increase raptors' oxygen requirements in flight and damage their delicate lung sacs preventing long distance flying. GPS-tracked migrating flocks deviate hundreds of miles off course or circle back to steer clear of thick particulate matter. https://pmc.ncbi.nlm.nih.gov/articles/PMC9286671/; https://naturecanada.ca/news/blog/when-the-sky-turns-gray-what-smoke-means-for-birds/; https://www.audubon.org/news/new-study-first-explore-how-wildfire-smoke-derails-bird-migration.

Non-raptor Observations:
As we drove towards the watch at 10:00 a.m. DST we saw two paragliders at ridge top level, we could see the same two at 11:19 a.m. 200 ft above the mountains to the north and by 12:20 p.m.they were back around the watch. Other paragliders initially had difficulty getting any lift. I could see one going in a circle within a thermal but not gaining much height, eventually managed to go up a few hundred feet above the watch level. CORA 4, WTSW 1, VGSW 1, WBNU 1.

Predictions:
Mostly sunny and hot, with a high near 100, which could mean less smoke. West wind 7 to 9 mph becoming northeast in the afternoon. Winds could gust as high as 15 mph.

Re: [cobirds] Common Nighthawk, Louisville, Boulder County

I've seen a pair in our Louisville neighborhood as well as above Walden Reservoir in North Park. 
I get pretty excited to see them because the Common Nighthawk isn't so common anymore, but maybe they're recovering a little?
Here's a pic I took in Walden.

There must have been at least 20 plus a Barn Swallow or two. It reminded me of the late 1990’s and the 5:00 PM hour when the nighthawks were very regular.
