Visitors:
2 hikers asked whether we had seen any eagles, and I replied - 2. Overheard conversation between 2 hikers. Man - I don't know any of the native birds. I heard chirping. Woman ( confidently) - It was probably a sparrow. There are mud sparrows which are protected. Since they didn't ask me, I didn't intervene.
Weather:
Denver very hazy, also a white cloud at the horizon between north and east with a gray band exactly in between it horizontally, which we hadn't seen before, and we realized there appeared to be smoke coming from the area of the Rocky Mountain Arsenal NWR, so it looked likely a controlled burn. At 12:00 noon MDT the smoke increased tremendously with the smoke rising and sweeping North, and very curiously a white cumulus cloud on top of it, probably because of humidity from burning of the grasses being released rising until it reached the dew point when it formed a cumulus cloud, termed pyrocumulus. By 10:00 a.m. MDT they were already small puffy clouds to the South moving to the SE, typically capping thermals, with moderate cumulus beginning to form in the West by 10:30 a.m. The 'seeing' was hazy to the South and we had difficulty keeping hawks in view in our binoculars.
Raptor Observations:
The first migrant hawk was an RT at 10:17 a.m. at level 4 height of flight. GE 2 adult migrants at 12:44 p.m. and 1:15 p.m. and unusually late migrant TV. Curiously we saw no accipiters. After 1:00 p.m. there were only 2 migrants counted, and I wondered whether the hawks were catching thermals instead. We had excellent cloud cover in all directions especially in the last hour when it started at 55% and ended at 85%, we scanned low and high in every direction and did not pick up any other than over Lookout Mountain, though we did see 92 RBGU in many different groups up to 28 extremely high in the sky, flying SE. So either the hawks were not flying or more likely they were flying beyond binocular range, as the height of thermals was almost 7,000 ft above the watch. This was another day like yesterday where the only migrant hawks found were over Lookout Mountain, probably as the thermals were not very strong earlier in the morning, and hawks preferred the ridge lift. The advantage of having two watchers is that while Liza was looking for hawks all over, I concentrated mainly on the top of Lookout Mountain scanning with binoculars more frequently than I normally do when alone, thus finding more hawks then I did yesterday with similar weather conditions.
Non-raptor Observations:
3 paragliders at noon had no lift and could not even reach the level of the watch, this being expected with the Soaring Forecast from the NWS expecting lift at 12 feet/second and thermal height at 9580 feet AGL by 11:45 a.m.
Predictions:
A 30 percent chance of showers, mainly after noon. Mostly cloudy, with a high near 75, winds from the W>SW>SSW. The winds aloft are going to be similar, light from the SW>SSW.J
