10/4/07
St. Paul, AR (36 N, -94W)
Mrs. Lawrence's Sixth Grade Class counted 38 migrating monarchs during
thirty minutes.
10/4/07
Wichita, KS (38 N, -97W)
In a 15 minute period 2 monarchs were sighted in our outdoor classroom
area. We observed starting at 10:29 am. It is a warm sunny day here in
Wichita, Kansas. Lastweek we spotted 8 at this same time of day, but in
only a 7 minute period.
10/3/07
Kingfisher, OK ( N, W)
Hundreds of Monarchs moved across central Oklahoma today. I saw at least
10 per minute from about 9 a.m. to 12 noon. The numbers dropped off after
that. Some flew lower, and stopped to nectar in the yard for a while,
and were gone. But, there was still a steady trickle of them coming until
6:00 p.m.
10/1/07
Ponca City, OK (36 N, -97
W)
I got a call this morning from a good friend who said they counted just
over a thousand monarchs in just 30 minutes. They were 5-7 miles south
of Ponca City driving around on country roads. They were driving in the
wide open spaces. The butterflies were low to the ground, mid-level, and
many were quite elevated as well!
09/30/107
Canton Lake, OK (36 N, -99
W)
I just received an ecstatic phone call from my in-laws who are at Canton
Lake in Oklahoma. They said it had been quiet with no Monarch sightings
Friday, Saturday and Sunday morning but now..... at 2:15 pm Sunday afternoon,
an explosion of Monarchs are flying over the lake. A cool front has come
through and with it, more Monarchs than they've seen so far. A steady
stream flying directly over the lake, hundreds at a time, coming through
in waves.
09/29/107
Chincoteague National Wildlife Refuge, VA (37 N, -75 W)
Spectacular migration day! Approximately 4,500 Monarchs were flying southwest
along ocean shore from 10AM to Noon. Most were flying low < 10 feet
off the ground and fighting the wind to avoid being blown
out over the ocean. At over wash areas - where there is no dune or vegetation
to provide any protection from the wind - about one out of three were
being swept out over the ocean. Some were able to make it back to shore
with great effort.
09/28/107 New Madrid, MO (37 N, -90
W)
Noticed lots, probably a hundred in an hour, of Monarchs moving across
the school property yesterday (9/28). All of them moving in the same direction,
south.
09/30/107
Asheville, NC (36 N, -82
W)
Counted 210 Monarch's in 1 hour on the Blue Ridge Parkway near Asheville,
NC. Once over the tree line from the north, they floated lazily down the
valley traveling south toward South Carolina. A few stopped to nectar
on Milkweek and Golden Rod.
09/30/107
Brevard, NC (35 N, -83W)
We saw 39 Monarchs in Cherry Cove Gap. We got there at 4:15 p.m.
and stayed there for around 40 minutes.
09/27/107 Augusta, MO (39 N, -91
W)
We saw over 10 monarchs in a 2 minute period flying near a farm field
and road. It was about 80 degrees and calm winds.
