Monarchs have been roosting in my yard every night since September 1.

Tuesday, September 24, sunny and windy. High temps low 80s. Wind SW approximately 10-20 with higher gusts to 30 in afternoon. Showers and storms possible overnight.

Surprisingly, still not much nectaring going on Tuesday although did notice a few periodically. Still predominantly nectaring on zinnias, tithonia, etc. This is noteworthy considering the amount of monarchs still in the trees today. Seems with the high SW winds, that they only changed roosting locations to the NE side of trees rather than nectaring or migrating. At 2 pm located many large and small roosts throughout maples and walnuts in lowest points of yard. Very easily startled at this time of day. Later in evening also noticed many roosting low in bushes and tall weeds to avoid the strong winds.

When I checked roosts at 7:30 am Wednesday I located approximately 1000. Roosts set up on north and east sides of walnuts, maples and ash in lowest point of yard. One walnut has approximately 400 and one maple approximately 300. Many singles and many smaller roosts of 5-50 scattered about other trees. Temperature low 60s, sunny and foggy. Wednesday is to be low 70s and partly sunny with W winds 5-15.
