The average pack size in North America is eight wolves and 5.5 in Europe. [44] The average pack across Eurasia consists of a family of eight wolves (two adults, juveniles, and yearlings), [37] or sometimes two or three such families, [41] with examples of exceptionally large packs consisting of up to 42 wolves being known.

As of 2018, the global gray wolf population is estimated to be 200,000–250,000. [1] Once abundant over much of North America and Eurasia, the gray wolf inhabits a smaller portion of its former range because of widespread human encroachment and destruction of its habitat, and the resulting human-wolf encounters that sparked broad extirpation.
[citation needed] Wolf populations only began declining in the Iberian Peninsula in the early 19th century, and was reduced by a half of its original size by 1900. Wolf bounties were regularly paid in Italy as late as 1950. Wolves were extirpated in the Alps by 1800, and numbered only 100 by 1973, inhabiting only 3–5% of their former Italian ...

[ 60 ] : 676 Fathers make visits to their offspring until they are weaned at 10 weeks of age; also, once the young are about six months old, some reconnect with their fathers and travel together ...

The eastern wolf has two proposals over its origin. One is that the eastern wolf is a distinct species (C. lycaon) that evolved in North America, as opposed to the gray wolf that evolved in the Old World, and is related to the red wolf. The other is that it is derived from admixture between gray wolves, which inhabited the Great Lakes area and ...
