nubilus- Klinghammer and Laidlaw 1979) reached similar conclusions. baileyi- Servin 2000) and Great Plains wolves ( C. Mech and Boitani (2003), based on Peters and Mech (1975), reported for wolves in the Upper Great Lakes Region of North America that “territorial advertisement and defence tend to peak during the breeding season.” Studies of captive Mexican wolves ( C. The limited literature on seasonality in wolf howling is inconsistent. By relating the seasonality of howling to other seasonal changes in wolf behaviors, we hoped to contribute insights into both the triggers and the consequences of howling. Our objective was to examine seasonal changes in the frequency of occurrence of wolf howls and howling replies to understand better their behavioral and ecological significance. Current understanding of wolf howling is based on “evidence that ranges from speculative through anecdotal to quasi-experimental” ( Harrington and Asa 2003). Detailed studies of their undisturbed behavior are few because they all are somewhat elusive and require large study areas. Most group-living canids (dingoes, Canis lupus dingo coyotes, Canis latrans red wolves, Canis rufus gray wolves, Canis lupus and eastern wolves, Canis lycaon), hyaenids (spotted hyenas, Crocuta crocuta), and felids (African lions, Panthera leo) engage in long-distance vocal communication.

Because our results may reflect a high-density, unexploited wolf population, comparative studies under other conditions would be useful.Ĭanis lupus, communication, howl, vocalization, wolf, Yellowstone We relate these seasonal changes in total howling and interpack answers largely to breeding and spacing behavior in pre-breeding and breeding seasons, and intrapack answers to pack cohesion in other seasons. Although not independent, the frequency of both total howls and interpack howling rose throughout the fall. Single howls stimulated distant pack members to answer with increasing frequency as the summer progressed. Howling frequency remained low all summer, during which time answers switched abruptly and almost exclusively from interpack to intrapack. Following the breeding season, overall howling abruptly decreased through March and April, although howling at den sites was frequent, particularly in April and May. These howling peaks correlated with elevations in estradiol, testosterone, and luteinizing hormone reported elsewhere. Answers during these seasons were predominately interpack howls. Pack howls primarily, but also single howls, were most common during these seasons. Howling was 5-fold most frequent in the pre-breeding and breeding seasons. In Yellowstone National Park, Wyoming, United States, we examined seasonal changes in occurrence of wolf howls and howling replies based on more than 11,000 unsolicited howls given over a 10-year period. Understanding its behavioral and ecological significance suffers from few quantitative studies in undisturbed, wild populations.
