Tree by DuSable Harbor

This picture was taken the afternoon of 9/12 by two of my neighbors.

It had rained for about 3 days with little breaks up to that point so it seems as though they were taking cover there during the weather. The next morning 9/13 they were not all gathered together but flying around the trees and area. I have been talking with my neighbors and over the past week 9/9 - 9/13 we had all noticed seeing many flying around our neighborhood past our windows. We live in downtown Chicago so we were all noting that we were surprised to be seeing so many out our windows and balconies being in high rises.

The number was just an estimate because they were in more than one tree and have been flying around our neighborhood so much so I really have no idea how to arrive at a good estimate of how many there were. It might be more in the hundreds? I’m not sure.

his is a tree next to DuSable Harbor in Chicago, IL. There are trees and plants along the lakefront but then inside our neighborhood square there is a park with lots of flowers. The park I am referencing is Lakeshore East Park in the middle of the block.

Overnight Lows were about 60 F

I don’t recall the wind situation but the trees they were in are somewhat sheltered from the wind, and the park is somewhat sheltered from the wind because it is surrounded by high rise buildings.
