Photograph taken on 02 Sep 2019 at 6:17pm.

There was 1 roost, but about 12 adult monarchs visible (to me) in the cluster, and another two monarchs nectaring on the milkweed below. There was one smaller cluster elsewhere in the same tree, and smaller clusters in neighboring trees.

There were nectaring opportunities in the patch of milkweed directly below the tree -- two adult monarchs are visible feeding on the flowers in the lower left quadrant of the photo.

The hi/lo temperature on 02 Sep 2019 in Chicago was 83F/62F, but I regret I do not know the temperature at the time the photo was taken, nor the wind direction. This location is not really well-protected from the wind. In general, these branches wave quite a bit - I marvel that the monarchs would find these branches restful places to stop.
