In previous years we would find early migrators at this site and tag 25 to 125 depending on the year. This year we returned 3 days in a row and found at most 4 monarchs and all but one were worn and breeders. Record high heat and drought (1/4 the normal monsoon rainfall) appears to be affecting the monarch population despite abundant fields of milkweed and nectar available. First time since we began monitoring in 2006 to see so few monarchs at this location.
