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

Wednesday, September 25, sun and clouds off and on. High temps low 70s. Wind W approximately 5-15 with a slight northerly feel as well.

Some nectaring going on Wednesday did notice a few monarchs periodically. Still predominantly nectaring on zinnias, tithonia, etc. I also have some tropical milkweed blooming that seems to be hot as well. At 2 pm located a few large and small roosts on E sides of maples and walnuts in lowest points of yard. Very easily startled at this time of day. At around 4 pm noticed 20-30 flying in, some well above tree tops.

When I checked roosts at 6 pm Wednesday evening I located approximately 600 which could be shy of actual numbers. Roosts set up on east sides of walnuts, maples and ash in lowest point of yard. I located four large clusters of 100-200. Many singles and smaller roosts scattered about other trees. Temperatures mid 60s and overcast. Overnight temps to be around 50 with Thursday forecast 72 and sunny with SW winds 5-10.
