Whisper was born in a wild herd in Nevada. When she was a young adult, she was rounded up with other herd mates by the Bureau of Land Management (BLM). While in the BLM round-up pens, Whisper gave birth to a bay filly. Six months later, Whisper and her filly, Shadow, were adopted by a man from Northern California. Her new owner kept the two horses for the mandatory year, received legal title to the mustangs, and then took them to auction.

Whisper and her filly were rescued from the auction and brought to the Sanctuary, where they would spend the rest of their lives.

When the two horses arrived at Redwings, they were very fearful of people. After much loving care and handling, Shadow became very comfortable with people, but Whisper remains very shy to this day.

When you look at Shadow and Whisper, it is very difficult to tell them apart. We have discovered that Shadow has a few white hairs at the base of her tail and also has a tiny snip in addition to the star on her forehead.

Not long after Whisper arrived at Redwings, she gave birth to another foal, a beautiful roan colt who we named Mirage. After Mirage was weaned, Whisper was reunited with Shadow, and they were turned out into a pasture with another BLM mustang named Reveille.
