Observers: Ajit Antony, Jared Loftis, Jason Walker, Liza Antony

Visitors:
Today's was a DFO trip to Mount Zion Hawk Watch. Ajit, Liza, and I have 5
visitors as part of the trip. Two attendees ended up leaving early due to
illness. We had great help from both Jason and Jared who had keen eyes and
great focus at the watch. This was Jared's second week of birding and he
proved to have the makings of a great hawk watcher (and general birder).
Thank you for everyone who attended the DFO trip today and we hope to see
you at the next Mount Zion trip sometime next month.

Trip attendees aside, we had a steady stream of visitors, but most people
noticed that we were instructing others and left us mostly alone.


Weather:
Beautiful morning to start the watch today. Low 70s and all blue sky.
Hardly any wind at all for the entirety of the watch. Cloud cover started
to slowly increase as the morning progressed. Near the end of the day, the
clouds became darker as more stormy weather hung around the mountains.

Raptor Observations:
First migrant of the day was a SH at 9:24 AM. 13 minutes after that, we had
a beautiful rufous intermediate morph RT migrant that gave good looks to
everyone. Compared to a true dark morph, rufous morphs will have a very
dark belly band, but the upper chest and lower belly will be a dark rusty
color (rufous). It is important to note that these polymorphic RTs belong
to the Western ssp. (calurus).
Most migrants were initially found near the Mesas and Green Mountain. Our
first OS' were all seen within 20 minutes of each other starting at 9:51
AM. A small group of 3 SW migrated together (as they are known to do) at
10:27 AM. It was a very good day for migrants and the birds were steady
throughout the day.

Non-raptor Observations:
First paraglider took off at 9:51 AM. At 10:00 AM we had great views of a
22.5 degree sun halo.

Predictions:
Tomorrow should show similar weather as today with afternoon clouds. We can
expect more Eastern winds and migrants!
