Sometimes, the spots will persist throughout a horse's lifetime.Ĭhubari spots are similar, but are usually larger, often egg-shaped and egg-sized. In many cases, the spots appear and grow in number for a period of years, and then gradually fade away. Seeing Spots:A variety of non-Appaloosa spots do occur in many breeds:īirdcatcher spots, named for the Thoroughbred stallion who exhibited them, are small, round, white spots scattered throughout a horse's coat. I gather he has sired some foals, but as of November 2011, I'm not aware of any brindled or roan offspring. He was at stud Stoneybrooke Farm in KY as of 2009. Pictured at right is Natal Classi, a Brazilian Warmblood imported to the USA. (More about this remarkable family on my TB color page.) Given that most horse colors are thousands of years old, new mutations like this are exceedingly rare. To the best of my knowledge, CAB's foals have never been genetically tested, but his roan daughter Slip Catch has produced two roan daughters herself. That is significant because true roan was not present in the TB population until that point. Simply put, that means that the white brindled color is unlikely to be passed on to a horse's offspring, but in at least one case, the mutation has resulted in unique offspring. The well-known Thoroughbred stallion Catch A Bird (pictured below left) sired four phenotypically roan foals. While it is possible that white brindles are chimeric (and certainly some may be), the current thought is that the color is either the result of a one-time mutation or may be the result of pigment cells not migrating from the topline during development in utero (a somatic mutation). Reverse or White Brindle:Most brindle horses have dark stripes on a lighter body color, but a rare few have white stripes on a dark body color.
