What drives the rut here

Pennsylvania's rut is the most studied in the country thanks to a decade-long Game Commission fetal-rate study spanning 6,000+ does collected from 2000–2007. Peak conception clusters tightly between November 13 and 15 across nearly every Wildlife Management Unit. Year-to-year variation is small — photoperiod, not weather, dictates timing. The PGC's published median conception dates remain the gold standard for predicting Pennsylvania rut activity.
