All of the mares, are hyper-vigilant with their new foals, this is certainly true for the first several weeks. Horses, being a flight response animal, are ever watchful for reasons to flee. Even suspect sounds or the slightest movements in the distance warrant consideration for moving away to a safer distance. I constantly find myself scanning the horizon and surrounding brush to identify what has caught the attention of the horses. As the foals grow in strength, size, and independence, the mothers are still available at a moments notice. This same behavior is true of confined, domestic mares with foals because motherhood is a strong, universal experience. However, in a free range environment, nature dictates the serenity of the days and nights, often in very unexpected ways.
