We have lots of rodents! I was reminded that they come and go in winter. Many of our critters become dormant, if they don't migrate.
The question is which ones hibernate?
Properly speaking, however, use of the term [hibernate] should be confined solely to homoiotherms—i.e., birds and whose feathers or fur serve as insulation to reduce heat radiating from the body and aid in the maintenance of constant body temperatures, which normally are independent of those of the environment.I found an interesting reading comprehension passage, with questions, that explains hibernate and estivate, as the critters manage in our harsh climate in Canada. Our critters have choices: hibernate (sleep in winter), estivate (sleep in the heat), migrate. I think we need another word, as the tree rats are waking from hibernation on an irregular basis.
Yet, the red squirrels, the black and gray squirrels, have been quite active. I haven't seen the chipmunks for a month, or so.
