Million Monarchs Fill the Sky
We walked around for a little while, still looking for roosts, not seeing too many migrants. Seeing some migrants but not too many. But by 11 o’clock--between 11 and 12 o’clock--they were passing overhead by the millions.
Millions of butterflies were up there kettling. You would focus your binoculars on near ones, on those in a kettle, and you’d keep changing the focus toward infinity and more butterflies would appear, higher and higher in the sky. It was just absolutely phenomenal. They continued just pouring over until about 1 o’clock and then they began to thin noticeably. And then we left that area, the Cienegas de Gonzales.
I’ve been along the route of the migration maybe 15 times, and I’ve seen some pretty spectacular stuff, but I think this is the most butterflies I’ve ever seen in migration over a particular area. I mean, this compares in density to what you see in early Nov at the butterfly colonies when they’re just arriving. The densities were just stupendous, they were just absolutely astounding. Seeing a million butterflies passing over is kind of magical.
