Abstract

A study was conducted in 1975 on mountain goats (Oreamnos americanus) crossing a highway to visit a natural mineral lick. Eighty-seven successful crossings of the highway involving 692 mountain goats were observed, and an estimated 812 crossings occurred during the 1975 lick season. Crossing success was associated (P < 0.05) with the size of groups, all groups (2-55 goats) being more successful than individuals. Crossing success was also associated (P < 0.05) with sex and age of the group leader, the most successful groups being led by an adult nanny with kid at side. Successful highway crossings after July 1 were significantly crepuscular (P < 0.005). Collision hazards and high disturbance during crossings suggested that a goat crossing should be constructed and visitors should be restricted from the crossing area.
