Horses Making Choices Using Symbols

Mr Ed was a TV show featuring a talking horse (a scheming talking horse, to boot) and his hapless owner, Wilbur. My late Mum first saw Mr Ed on a visit here from Scotland, and she was smitten from the get go.

If you spend time around animals like dogs, cats and horses, you tend to begin to realize they are smarter that you may have originally supposed. We also see evidence of this from scientists (those who take the time to bother). The latest case in point is a study that suggests that horses can comprehend symbols.
Scientists taught 23 riding horses of various breeds to look at a display board with three icons, representing wearing or not wearing a blanket. Horses could choose between a "no change" symbol or symbols for "blanket on" or "blanket off."
