Coyotes Nipping At Our Heels: A New Suburban Dilemma, Robert M. Timm
11th Triennial National Wildlife and Fisheries Extension Specialists Conference (2006)
In the 1970s, coyote attacks on humans in urban and suburban environments began to occur, primarily in Southern California. Such attacks have increased in number, and since the late 1980s coyote attacks on people have been reported from at least 16 additional states and 4 Canadian provinces. Attack incidents are typically preceded by a sequence of increasingly bold coyote behaviors, including attacks on pets during daylight hours. In suburban areas, coyotes can habituate to humans as a result of plentiful food resources, including increased numbers of rabbits and rodents, household refuse, pet food, water from ponds and landscape irrigation run-off, …

The information content of coyote (Canis latrans) vocalizations is poorly understood, but has important implications for understanding coyote behavior. Coyotes probably use information present in barks or howls to recognize individuals, but the presence of individually-specific information has not bean demonstrated. We found that coyote barks and howls contained individually specific characteristics: discriminant analysis correctly classified barks of five coyotes 69% of the time and howls of six coyotes 83% of the time. We also investigated the stability of vocalization characteristics at multiple distances from the source. Recordings were played back and re-recorded at 10 m, 600m, and …
