Mothers with Babies (or sometimes dads): Bison

Going through my photos I realized I have a number of Mothers and/or Fathers with their youngsters. So, why not a couple of posts about Animal Families, starting with the American Bison.

Bison mate in August and September; gestation is 285 days. A single reddish-brown calf nurses until the next calf is born. If the cow is not pregnant, a calf will nurse for 18 months. Bison cows are mature enough to produce a calf at 3 years of age. Bison bulls may try to mate with cows at 3 years of age, but if more mature bulls are present, they may not be able to compete until they reach 5 years of age.

  1. Given that we've long associated Azure Gate with fertility (was our granddaughter in fact conceived there?) these posts are apt. Hope all babies moms, dads, grandparents and others are handling the heat etc well.
