Further drop in Temp at Staten Island migration observation location by coastal hills/milkweed fields on South Shore of Staten Island. Three of my college students that agreed to
spot for me, only saw in the 2-3 hrs. they were at site:
7, 14, 10 Mon. Bfs. I went out this mornng for two hrs., &
only saw 12. It appears that our core concentrations (which
were smaller when spotted than last year) have mostly moved
on. Thanks.
