9/25/07
Kingfisher, OK (35.91 N, -98.02 W)
1st
wave of Monarchs waltzing across Kingfisher, Okla. Today, about 4:45 p.m.
I counted about 65 Monarchs in 1 minute, high in the sky, heading SW,
definitely on a mission. No stopping to nectar today, no slowing down
to roost tonight. Front came thru. Temps in the upper 60's, cloudy, with
a light NE wind. Woo! Hoo! Come on Monarchs! Be ready Texas!
9/25/07
Ponca City, OK (36.67 N, -97.05 W)
I'd think
that today could also be considered a Peak Monarch Migration sighting
for this area. I counted 213 of the beauties just today. From 2-4:30 PM,
I counted 208! They were heading south at a height ranging from 8-35 apx.
They were riding the northerly breeze brought by the passing of a cold
front which dropped temps by over 15 degrees during the day. I delighted
in seeing one group of 4, one group of 3, and several groups of 2 during
the peak time this afternoon. The remainder of them were flying solo.
9/24/07
Kittery Point, ME (43.10, -70.69)
My daughter
and I saw more than 20 Monarchs this afternoon around 2 pm on our 45 minute
walk. Almost all were feeding on the wild Aster blooms, not many were
in flight. It was a very breezy day.
9/23/07
Kansas City, MO (39.10, -94.60)
In one hour I observed 13 Monarchs. Late afternoon 3:45 to 4:45 pm.
9/23/07
Fire Island, NY (40.62, -73.26)
While walking along the shoreline at Robert Moses State Park we saw 20
to 30 Monarchs per minute traveling northwest.
9/23/07
Grandfather Mountain, NC (36.11 N, -81.81 W)
My friend
and I tagged 125 monarchs in four hours before we ran out of tags. Our
friends, Carolyn and John were able to count 1033 monarchs during that
time. John looked out from the ridge through his binoculars and could
see lots more flying. So we know there were many monarchs passing by that
were not counted.
