Monarch PEAK Migration

Date: 09/07/2021

Number: 800

After stopping to observe a roost of Monarchs adjacent to Leamington District Secondary School at 8:30 AM, I noticed Monarchs in flight headed to a field of wildflowers. I walked over to the field and observed hundreds of monarchs nectaring on the predominantly red clover in full bloom. I took this photo from the edge of the field but as I scanned the field and looked closely I could see monarchs on every square centimetre of the field. A 'for sale' sign indicates that the parcel of land is 8.7 acres. Not being good at estimating large spaces but owning an acre myself, it might be safe to say that there was a hectare of Monarchs. More were trickling in as I left to beg forgiveness for parking in the driveway of a nearby business. Sunny, warm 21C with a steady moderate south west wind. Please see separate report under roosts for the roost near the high school. Thanks should be given to the land owner for allowing this parcel to be left wild for Mother Nature.
If you 'build it' or in this case 'leave it' . . . they will come.

[Additional information contributed by observer, added by Journey North, 09/13/21]:
For the monarchs in the field I paced off a quadrant in one corner and then multiplied that section by the number of other sections I paced off by walking east-west and north-south along the perimeter of the field in order not to disturb the monarchs. I also paced off the section of the field where there were no monarchs and subtracted that from the original total. Picture in your head if you will a grid pattern as used in mathematics. Observation over the course of roughly an hour.
