I had never heard of birdcatcher spots until recently. I worked for a woman with a solid bay mare who one day, suddenly had spots. Several would appear at a time. They weren't bumps, bites, or wounds.. They literally were perfectly round spots about the size of a quarter of pure white hair. She had them all over her neck and even had one on the tip of her ear. It was the most bizarre thing I had ever seen! The vet said it isn't anything to worry about and she is perfectly healthy.. Just a little odd looking. Beautiful if I do say so myself.
