Peak August migration along Lake Huron shoreline today! I and a friend (Larry) counted 409 monarchs in 7 hours. I also netted and tagged 4 (AAEL-934 to AAEL-937). Here is the hour by hour count:

The temperature at the start and finish of the count was 64F. High was 70F. There were some high clouds all day coming out of the west. No monarchs were counted the last twenty minutes of the count. Some monarchs were coming straight east off the lake. There were many other people on the beach enjoying the monarch migration; especially the monarchs flying close to the shoreline.
