So many monarchs on a tree on the golf course of the island. Way too many to count!

[Additional information contributed by observer, added by Journey North, 09/18/21]:
We were on vacation on an island in Lake Ontario about ten miles off Henderson Harbor when we spotted a tree full of butterflies. There were more butterflies than we could count just covering the tree. We became interested in why the butterflies were so far north this time of year since we all thought that they wintered in Mexico. We imagined that they’d be further south by now and got curious enough to google “Monarch migration” and came across your site. Just being a visitor to the island, I really don’t know about the wind, tree type, etc. The one thing I know is that there is a lot of milkweed on the island. As to the number of butterflies we saw, I wanted to report “too many to count” on the input form, but instead I entered 1000 as the estimate based on the overwhelming number we saw on the tree. I suppose the number could have been 2000, or perhaps only 200, as we didn’t do a scientific count, we just took a guess.
