Golden, Greater Denver, Colorado, USA
This is a new raptor migration site identified and designated in mid-September 2024. This is Colorado's 1st fall hawk watch site and the state's second spring watch site. Many raptors seen c. 1.5 miles to the West from Dinosaur Ridge, may be directly overhead at this site, we are hoping. To get to the site which is along Lookout Mountain Rd. in Golden, enter either Windy Saddle Park or Mount Zion into Google Maps on your favorite navigation app, or enter the coordinates 39.7368,-105.2454. From the parking lot ascend the stone steps to the watch site. Anyone is welcome to join us if they want to see the spectacle of spring raptor migration, whether they know nothing or know a lot regarding identifying raptor species.

Visitors:
A woman was curious as to what we were looking at and when I explained, she thanked us. Two young women with little babies hiked up and chatted with each other for about an hour. They asked what we were looking at and I explained, and she asked with my almost 40 years of raptor watching, could I see the effects of global warming. I explained that there are too many variables such as there could be reduced migrants as a result of unfavorable winds, and perhaps the only way anyone could tell, was if a researcher looked at multiple hawk watches in the same area over a long period of time. A young woman after taking video selfies of herself looking coquettish, wanted to know what we were doing. I explained. She said she saw some magpies, and I said they were common here and that there were Mountain Chickadees. She was not familiar with the species and I showed it to her on Merlin comparing it with the Black-capped. She was quite interested. After she left an older man came up and asked me what I was showing her. He said his wife was a birder and had bird books. I told him about the Merlin app. His wife said that she did not know much, so she did not need the app. I showed the man all the various features of the app, and he immediately added it to his phone - imagine, he was the non-birder the family!
Weather:
Today's forecast for light winds from the SSW, then to the SSE, and the winds on the ridge were fairly close - from the ESE. Good transparent cirrus cloud cover from South to East to North, and to some extent overhead. Initial visibility 19 km increasing to 39 km to DIA after the first 2 hours due to a thin line of fog along the ground, east of Denver going from north to south. Mount Blue Sky to the SW was again clear at 39 km all day. Surprising we did not see more raptors with the cloud cover and favorable winds that we had, in addition there was good lift according to the Soaring Forecast at 4.2 meters/second, with thermals predicted going up to 10,447 ft AGL - above ground level by 11:45 a.m. MDT. The Southern component of the SE winds should have pushed raptors northward, while the Eastern component of the SE winds should have pushed any migrants flying East of Denver toward the watch. The atmosphere was somewhat grainy - distant local birds were difficult to see for a while, presumably when they turned.
Raptor Observations:
At 12:42 p.m. MDT I was watching 2 RT far to the East using my scope, and one of them flew toward Lookout Mountain, a Prairie Falcon entered the view of my scope, flew Westward, and I willing it to fly North, at one point directly South it came close enough that I felt I could find it with binoculars, and I did, it kept rising, circling, eventually going more NW, extremely high at the limit of binoculars, we watched it for about 5 minutes until we decided was a migrant, the Bird of the Day. The first raptor of the day, and only other migrant was a distant RT far to the east at 10:44 a.m. MDT. Non-migrant raptors: GE adult at 1:49 p.m. flying just above the Eastern end of Lookout Mountain, dropped below and was lost among the pines. The usual 3-4 RT flying over and landing on Lookout Mountain, generally moving East or West, occasionally South or SW. One RT came up from the south directly overhead, soared, constantly rising until it reached far to the NE, and then turned Eastward - not counted.
Non-raptor Observations:
There was a solar corona with only two rainbow rings. 1 paraglider a little before we left. Black-billed Magpie 2, Common Raven 5.
Predictions:
Light West winds, changing to SW. I'd be curious to see what we'd get.
