Observations from Citizen Scientists: Week Ending Sept. 18, 2008

What Were the Monarchs Avoiding?
The people quoted below saw monarchs that seemed to be avoiding something. The butterflies were traveling in places where the local geography is dangerous for them. In each example, there was something large that the monarchs did not want to fly across.

  • What is the name of the large geographic feature that the monarchs were avoiding?

For Your Journal: Each week, choose your favorite monarch sighting and record your thoughts in your journal. >>

September 17: Leamington, Ontario (42 N, -83 W)
Here at Point Pelee National Park, we found around 600 monarchs roosting near the Tip this morning. A strong south wind will keep the monarchs here until the wind direction changes. (Note: The "Tip" is the tip of the Point Pelee Peninsula, the southernmost point of Canada.)

September 15: Port Stanley, Ontario (43 N, -81 W)
I counted approximately 350 monarchs flying west along cliffs on the north shore of Lake Erie today from 2-3 pm. I also sighted an afternoon roost of about 100 monarchs. They were roosting on old Queen Anne's Lace. Not nectaring, just resting. The area is known as Hawks Cliff, right along the north shore of Lake Erie, just east of Port Stanley.

September 15: Whitby, Ontario (44 N, -79 W)
Hundreds of monarchs sighted flying west, hugging Lake Ontario's northern shoreline. Hundreds were also resting in trees. There was a strong westerly wind, the aftermath of Ike, which blew through yesterday.

September 15: Freeport, Maine (44 N, -70 W)
We live on 10 acres of farmland on Casco Bay and we have for 7 years watched the monarchs migrate across our property. Today, 15th of September, 2008, my 7 year old daughters and I sighted hundreds of monarchs in our 7 acre field of mostly clover and fallwild aster. The field is on Casco Bay. We did not attempt to count the butterflies, but it was many hundreds. When the sun set, they went into the top of the tall oak trees on the side of our field.
