From Inside Ottawa Valley:
August is one of my favourite months for several reasons. One is that by its end, the biting insects start disappearing. Another is that the nights are deliciously cool and the days clear and bright. And last but not least, Algonquin wolves are howling.
Of course, wolves howl all year long. Howling is how wolves communicate not only to fellow pack members but also to other wolves. Howls are audible “no trespassing” signs that tell other wolves where property limits reside. Wolves howl to tell pack members their location, and to no doubt convey other information. Howling also seems to play a role in social bonding in a pack.
