My reporting this autumn from Cranberry Marsh Raptor Watch is very limited. As I am no longer driving I get there only when someone picks me up. I have agreed to keep the data records, sending weekly reports to Doug Woods.
It appears that the Broad-winged flight is over. Indeed the flight path for 90% of them was very much inland, taking many thousands of them between Lake Simcoe and Georgian Bay down along the north shore of Lake Erie. Over the past week we had several days of NW wind, rising barometric pressure and thermal updraft velocity over 300'/min., ideal for raptor migration. On Sep. 15 and 16 exactly 5000 Broad-wingeds were counted flying over CMRW. The aforementioned conditions were not met on Sep. 17 and 18--only 44 hawks were noted.
