There was a major Monarch migration push today here in NE Kansas...With the favorable NE winds, they were on the move SW...
This big fall roost was located at my supervisor's home in Lancaster, KS early evening...He & I are employed by KS Dept. of Wildlife, Parks & Tourism...I tagged 9 Monarchs today on my Mexican Sunflowers here in Atchison, KS...

I was back out to the Lancaster, KS Monarch roost mid-morning (9/21) & there were still around 500 Monarchs warming themselves in the morning sun on the east sides of the mulberry trees...I tagged 10 very quickly then headed back home here to Atchison where I've tagged 4 so far on our zinnias & Mexican sunflowers!...NC

This Monarch roost in Lancaster first showed up on Sunday evening, September 19th
The vast majority of the Monarchs were in a “Mulberry” tree...
We count them kind of like we count thousands of waterfowl at once, visually sectioning off 10 then 100 of them at a time going one direction, then we reverse direction & count again, taking the average of the two counts. As you said, it’s not an exact science!...

The weather was clear with variable east to northeast winds @ around 10mph...

This backyard roost has a thick shelter belt consisting of cedars & deciduous trees, giving the Monarchs shelter from the wind from any direction...

Nearby nectar sources are mainly maximilian sunflowers growing in road ditches or field waterways. They are in full bloom right now!
