Very magical day today. Witnessed the fall mass migration of Monarchs and Gulf Fritillaries. We didn’t have to move. For more than 5 hours the Monarchs and Fritillaries moved down along the beach over the wild grasses, plants and sand dunes. Conservative estimate by two of us was 5-10 per minute sustained for the whole time. Easily saw a thousand of each species. I saw more of these two species today than the accumulation of all the other days of my life. There were so many butterflies we were laughing trying to count them.
