The Monarch roosts have gone down quite a bit (On Sept 8 - saw about 50, On Sept 9 there were over 1000). The roosts I found were on Maple, White and Red Oak trees. They were viewed between 6-7:15pm, temp was 18C and very slight wind gusts. A low lying roost (10-15 ft off the ground) on a Maple tree had 50 Monarchs with more flying in. A big oak had between 80-100 with multiple branches of 10-25 Monarchs. Most trees with roosts were located on the east side of the Veterans Memorial.
