Number: 50

A number of monarchs feeding in a 10-acre field of flowering field radishes. I am conservatively estimating 50 individuals, but it could have been a multiple of this number.

Sept 25 Many hundreds, possibly thousands (my roost report)
Sept 26-28 Still hundreds, but less than on the 25th
Sept 29-Oct 16 Several to dozens of monarchs each day, except for some cold rainy days. We should have been more observant.
Oct 17-Oct 20 50+ each day

A friend who is tagging monarchs for Monarch Watch stopped today (Oct 20) and we tagged 14 monarchs. That was all the tags she had left. There were many more that we didn't tag (it's a big field), so I'm estimating that there were well over 50 out there today.

I've lived here almost 40 years, but I can't say for sure whether or not I've ever seen monarchs this late in the season. Certainly not in these numbers.
