Date: 09/28/2019

Number: 925

Goose Pond Sanctuary 7:15 - 7:35 a.m. The night before it was cloudy with a temperature of 64 at 6:00 p.m. and winds north at 4 mph (Madison), mostly calm at Goose Pond.

W7503 Kampen Road
- 20 on the south side of the one white pine, 160 on the north side of the spruce trees east of the power line; 545 on the north side of the 3-4 trees on the west side of the power line.

Cottonwoods - 200 on the 11- years old cottonwoods on the south side of Jill's (north) Prairie and north of the flat (wetland this year).

Saw 7 tagged monarchs in the spruce trees. J D Arnston also saw 7 tagged monarchs on September 27.

At 6:00 a.m. it was cloudy, 55 degrees, with north northeast winds at 12 mph (Madison);

At noon it mostly sunny, 64 degrees, with northeast winds at 11 mph.

The monarchs were still in the roost at 9:00 a.m.

We had 50 tags to use and six of us began tagging at 1:10 p.m. We stopped about 2:00 p.m. and only tagged 5 monarchs. One team of 3 drove in a Kubota 1 mile and saw and caught one monarch on New England Aster. The other team of 3 walked .5 mile and caught 4 monarchs (3 on New England Aster and 1 on Showy Goldenrod). They saw or missed about 4. Some monarchs were high and were seen coming from the north. They came down and began nectaring in the former pasture to the west of the buildings that contained a nice area with a lot of New England Aster and Showy Goldenrod that was almost done flower.

The first roost count was on September 4 and this will probably be the last count.
