Visitors:
Aaron Lefland from Connecticut who lives near Lighthouse Point Hawk Watch and has visited there, was in Denver for a conference on Land Management, looked up eBird hotspots and found the Mount Zion Hawk Watch (which Zak Hepler had recently requested hotspot designation), so we found him at the watch when we got there, he helped us find a number of raptors, we in turn helped him learn to identify raptors in flight. He had a number of passerine lifers today.
Weather:
Less hazy over Denver then the day before, again caused by an inversion layer we could see as a brown haze to the Northeast which gradually moved South. Cool, breezy and pleasant all day, winds from the ESE changing to ENE, cloud cover 30% increasing to 85% mainly cirrus in the morning with cumulus coming in from the West as usual by the afternoon, clear visibility initially only 5 km and increasing only to 19 km.
Raptor Observations:
The first two migrants were AK along the Kestrel Channel way below us at 9:39 a.m. MDT. In addition to AK, RT (mainly local) were seen along the channel, as did all the Steller's Jay seen. At 10:46 a.m. a migrant juvenile dark morph RT promptly IDed by Liza. Non-migrant raptors: AK 2, CH 1, RT 4, TV 6.
Non-raptor Observations:
Two paragliders at 10:00 a.m. had no lift, 8 after 11:00 a.m. had none to moderate left while by 11:45 a.m. some of them were really high, barely visible to the eye. CAWR 1 calling, STJA 12, VGSW 4, WTSW 6, NOFL 1, SPTO 1, AMRO 1, AMCR 1, CORA an unkindness or conspiracy of 26, HAWO 1, BLJA 1. Because of the inversion layer, lift was very poor at 2 ft per second with the predicted maximum height of thermal 5,114 ft AGL, though the migrants were flying much much higher. As we say, they hadn't read the prediction.
Predictions:
A chance of showers, with thunderstorms also possible after noon. Mostly cloudy, with a high near 78. Calm wind becoming east northeast around 6 mph in the afternoon. Chance of precipitation is 50%.
