Pack (canine)
Animals which typically predominate over others are associated with the term "alpha". Among pack-living wolves, alpha wolves are the genetic parents of most cubs in the pack. Such access to mating females creates strong selective pressure for intra-sex competition.
OR-7
By 2014, OR-7 had settled in the Rogue River watershed in the southern Cascade Range east of Medford, Oregon, with a mate. It is not known when the two wolves met, but DNA tests of fecal samples showed that she is related to wolves in two of the eight packs in northeastern Oregon. In early 2015, officials designated the two adult wolves and their offspring as the "Rogue Pack", the first wolf pack in western Oregon and the state's ninth overall since wolves returned to Oregon from Idaho in the 1990s. The batteries in OR-7's tracking collar expired in October 2015, and monitoring the pack since then has depended on trail cameras and live sightings. Meanwhile, other wolves have migrated into the mountainous cross-border region, and relatives of OR–7 have formed two packs in northern California.
