Article body
From the first paragraph of the "Behavior" section:

Columbian ground squirrels in Alberta hibernate around 250 days a year, with only 69–94 days of activity observed. The amount of time active varies depending on local climate as well as variations in behavior of animals of different sexes and ages. [10] Each sex and age group hibernate at different soil depths and begin hibernation when the temperature of their soil is at its warmest. During hibernation, the squirrels are positioned vertically in a tight ball. The temperature drops significantly, the heart rate slows and respirations are scarcely perceptible. [11] The first group to emerge are the adult males, followed by adult females, yearlings, then juveniles. Animals at higher elevations and latitudes emerge later. [10] They emerge from hibernation and start breeding earlier at low elevations. [11]

Thinking of adding this as its own small paragraph after the second paragraph in the "Behavior" section, as there are no discussions of lactation mentioned in the article:

Before their first hibernation, newborn Columbian ground squirrels only have a period of a few weeks to wean off their mother's milk. Because of this, the 27 day lactation period of the mother squirrel is the young's primary opportunity to get the nutrition necessary for surviving hibernation. The concentrations of most components making up the mother's milk vary throughout the lactation period, most dramatically seen in calcium, which typically experiences a 134% increase in concentration from the beginning of lactation to its peak (~17 days postpartum).
