On March 20 1992, Peter Sherrington and Des Allen were conducting a general bird survey in the Kananaskis Valley near Mount Lorette. Late in the morning Peter observed an adult Golden Eagle soaring high above the valley to the east of Mount Lorette. A short time after they saw two adults soaring over the mountain. These two birds were quickly joined by a third. All three moved off to the northwest, to be replaced a few minutes later by more birds moving from the southeast. By the end of the day Peter and Des had counted over 100 Golden Eagles migrating to the northwest. Two days later Peter led a group of amateur naturalists to the area to look for eagles and they were rewarded by seeing nearly 250 Golden Eagles flying from southeast to northwest in a single afternoon.
