THE HORSESHOE POSTURE IN MOOSE - A REACTION TO PERCEIVED THREATS
A behaviour pattern of bull moose was noted when confronted with aircraft during surveys and occasionally on the ground when threatened. The pattern is called the horseshoe posture and involves shifting of the back hooves toward the front hooves with the legs now forming a triangle with the abdomen. The pattern was noted in yearling, teen, prime, and senior bulls, but not cows. No head tilting was noted as described for caribou during the rut, but there was rubbing together of the tarsal glands. Bulls did not exhibit the horseshoe posture when confronted with an artificial head and antlers.
