A free-ranging Gray Wolf (Canis lupus), habituated to human presence (the author) on Ellesmere Island, Canada, learned to anticipate experimental feeding by a human, became impatient, persistent, and bold and exhibited stalking behaviour toward the food source. Only after the author offered the wolf about 90 clumps of dry soil over a period of 45 minutes in three bouts, did the wolf give up this behaviour. To my knowledge, this is the first example of extinguishing a learned response in a free-ranging wolf and provides new insight into the learning behaviour of such animals.

Dominance is one of the most pervasive and important behaviors among wolves in a pack, yet its significance in free-ranging packs has been little studied. Insights into a behavior can often be gained by examining unusual examples of it. In the High Arctic near Eureka, Nunavut, Canada, we videotaped and described an unusually prolonged and intensive behavioral bout between an adult male Gray Wolf (Canis lupus) and a male member of his pack, thought to be a maturing son. With tail raised, the adult approached a male pack mate about 50 m from us and pinned and straddled this packmate repeatedly over 6.5 minutes, longer than we had ever seen in over 50 years of studying wolves. We interpreted this behavior as an extreme example of an adult wolf harassing a maturing offspring, perhaps in prelude to the offspring's dispersal.

A two-year-old sibling Gray Wolf (Canis lupus) carefully captured an Arctic Hare (Lepus arcticus) leveret alive on Ellesmere Island, Nunavut, Canada, and delivered it alive to a pup 28–33 days old. This appears to be the first observation of a Gray Wolf delivering live prey to a pup.

A free-ranging canid killed near Caraquet, New Brunswick, Canada, in 2012 exhibited a mitochondrial DNA sequence of Gray Wolf (Canis lupus) origin and a Y-chromosome haplotype of Eastern Wolf (C. lycaon) origin. The animal, which is the first wolf recorded in New Brunswick since 1862, was identified as a Gray–Eastern Wolf hybrid (C. lupus x C. lycaon) based on analysis of its autosomal microsatellite genotype. Stable carbon isotope values (δ13C) suggest that the Caraquet wolf was of wild origin. Likewise, δ13C analysis suggests that a wolf–coyote hybrid killed in Quebec south of the St. Lawrence River in 2002 was also of wild origin. However, δ13C values for a wolf from the same region in 2006 suggest that this animal spent most of its life feeding predominantly on non-wild-source food items. Recent occurrences of wild-origin animals south of the St. Lawrence River demonstrate that wolves are capable of dispersal to formerly occupied areas in southeastern Canada and the United States. However, limited natural dispersal alone will likely not be sufficient to re-establish wolves in northeastern North America.

Urine-marking and ground-scratching were observed in an Arctic Wolf (Canis lupus) pack on Ellesmere Island, Nunavut, Canada, during 16 summers between 1986 and 2005. All previously known urination postures and ground-scratching by breeding males and females were seen, and incidence of marking and scratching was greatest when non-pack wolves were present. Observations of urine-marking of food remains supported the conclusion from a captive Wolf study that such marking signals lack of edible food.
