After three days of strong southwest winds, we were hoping that the Monarchs would be able to make some good headway in today's lighter, cooler, northerly breezes, and apparently, they did. While the numbers were not the biggest, they were unmistakably migrators as they fluttered in between 6:30 p.m. and 7:30 p.m. local time. Sunset was at 7:02 p.m.
There were many individuals roosting alone, with the largest 'group' that I found being three.
Weather was clear with a breeze from the NE at around 5-10 mph and a temperature of 73F. The high for the day was near 80F, with NNE breezes, and heading for a low tonight of 55F.
Roosts were almost all on west and south faces, and ranged from 8' to 15' off the ground. Trees of choice (in order of most to least) were Silver Maple, American Arborvitae, Bald Cypress and a few on the Norway Spruces. Noticed a good number nectaring in the yard this afternoon, with Tithonia, Aster and Sedum being the primary targets. Not sure if they were part of the overnighters or not.
Hoping the trend continues tomorrow evening.
