Yes thanks for the great post and pics. I was an ADC Trapper for the SD GF&P from 1977-92. I will always remember some comments made from one of the former state/fed. program trappers who worked for 25 years in Western SD. He commented that a majority of the coyote pups were born by the 10th of April and the female coyotes would start start to bring the pups up out of their dens by the 10th of of May. The pups were 30 days old at this time.
