In a word, no. There
is no relationship between the type of call an Olympic marmot utters and the
type of predator that elicited that call. Additionally, a detailed examination
of alarm call structure revealed no association between call structure and
predator type. Aerial and terrestrial predators elicit the full range of alarm
call types. However, when Olympic marmots alarm call in response to a terrestrial
predator like a coyote, they tend to utter more calls than when they call
in response to an aerial predator like an eagle. When Olympic marmots heard
multiple alarm calls, they became more vigilant than when they heard a single
alarm call and long bouts of alarm calling keep marmots looking around for
the potentially threatening stimulus.
